Furthermore, the scanning apparatus 30 reads, based on the control by the controller 31, the necessary status message to be reported among the various status messages STsp stored in the printer status message group memory region 34a2 depending on a status of the printing apparatus 20 retrieved from the printing apparatus 20 through the local interface 36 and displays the read status message on a printer status message display region 32b2 formed at the display unit 32b on the operation panel 32. It is to be noted that FIG. 5 shows a case where three status messages are displayable at maximum with respect to the status of the scanning apparatus 30 whereas two status messages are displayable at maximum with respect to the status of the printing apparatus 20.
With the image forming system 10 as described above, the printing apparatus 20 proceeds the sequence of operational steps such as shown in FIG. 6 to execute a process for displaying the status on the display unit 22b in the operation panel 22. It is to be noted that this process is stored in the NVRAM 24 as a program to be read and executed by the main controller 21 and to be executed in a case of change in the status of the printing unit 23.
As shown in FIG. 6, the main controller 21 first retrieves at step S1 the status message STp corresponding to a status having the highest priority PRp among the statuses occurred in the printing unit 23 in reference to the status messages STp having the priorities PRp from “one” to “m”, stored in the printer status message group memory region 24a1. The main controller 21 makes a judgment at step S2 as to whether the corresponding status message STp is retrieved or not.
Where making a judgment that the corresponding status message STp is retrieved, the main controller 21 displays the retrieved status message STp in the second line of the printer status message display region 22b1 formed at the display unit 22b in the operation panel 22 at step S3 and makes a judgment as to whether the priority PRp corresponding to the retrieved status message STp is equal to “m” at step S4.
The main controller 21 retrieves the status message STp corresponding to a status having the second highest priority PRp at step S5 where making a judgment that the priority PRp corresponding to the retrieved status message STp is not equal to “m”. The main controller 21 furthermore makes a judgment at step S6 as to whether the corresponding status message STp is retrieved.
The main controller 21 displays the retrieved status message STp in the third line of the printer status message display region 22b1 at step S7 where making a judgment that the corresponding status message STp is retrieved. The main controller 21 then makes a judgment at step S8 as to whether the warning level WLp subject to the status message STp retrieved at step S1 and/or the step S5 is equal to “one”, or namely as to existence of the status message STp having the attribute meaning the unprintable status.
Where making a judgment of nonexistence of the status message STp having the attribute meaning the “unprintable” status, the main controller 21 displays in the first line of the printer status message display region 22b1 the status message STp having the priority PRp of “m+1”, or namely the status message STp indicating the “printable” status and completes at step S9 this sequence of operational steps. On the other hand, where making a judgment of existence of the status massage STp having the attribute meaning the “unprintable” status, the main controller 21 displays in the first line of the printer status message display region 22b1 the status message STp having the priority PRp of “m+2”, or namely the status message STp indicating the “unprintable” status and completes at step S110 this sequence of operational steps.
Furthermore, where making a judgment that the corresponding status message STp is not retrieved at step S2, the controller 21 clears both the second and third lines of the printer status message display region 22b1 at step S11 and subsequently shifts this process to step S9 to display in the first line of the printer status message display region 22b1 the status message STp having the priority PRp of “m+1”, or namely the status message STp indicating the “printable” status and to complete this sequence of operational steps.
Where making a judgment that the priority PRp corresponding to the status message STp retrieved at step S4 is equal to “m”, or that the corresponding status message STp is not retrieved at step S6, the main controller 21 shifts this operation to step S12 to clear the third line of the printer status message display region 22b1 and then shifts this operation to the operational steps subsequent to step S8.
In the event of change in the status of the printing unit 23, the printing apparatus 20 selects, based on the operable level information, the status message to be displayed on the display unit 22b among the plurality of status messages STp stored in the NVRAM 24 upon processing this sequence of operational steps. That is, the printing apparatus 20 displays in the printer status message display region 22b1 the status message having the warning level WLp equal to “one” meaning the “unprintable” status in priority to the other status messages upon processing this sequence of operational steps. In a case of nonexistence of the status message as described above, the printing apparatus 20 can display in the printer status message display region 22b1 the status messages sequentially in the order of priority from highest to lowest. It is to be noted that the above mentioned display example of the printer status message display region 22b1 shown in FIG. 3 shows a display example in which the message for indicating the “unprintable” status is displayed in the first line, and in which the message having the priority PRp equal to “three” and the warning level WLp equal to “one”, for indicating the status that “the recording sheets run out” is displayed in the second line, and in which the message having the priority PRp of “m” and the warning level WLp equal to “zero”, for indicating the status that “the toner is running out” is displayed in the third line.
On the other hand, the scanning apparatus 30 proceeds this sequence of operational steps such as shown in FIG. 7 and FIG. 8 to implement the operational steps for displaying the status on the display unit 32b at the operation panel 32. Those operational steps are stored in the NVRAM 34, as a program to be read and executed by the controller 31. Among those, the operational steps shown in FIG. 7 are to be executed in the event of change in a status of the scanning unit 33 whereas the operational steps shown in FIG. 8 are to be executed in the event of change in a content displayed on the printer status message display region 22b1 formed at the display unit 22b of the printing apparatus 20.
The operational steps to be executed in the event of change in the status of scanning unit 33 are explained in reference to FIG. 7.
As shown in FIG. 7, the main controller 31 retrieves at step S21 the status message STs corresponding to a status having the most high priority PRs among statuses generated at the scanning unit 33 in reference to the status messages STs having the priorities PRs from “one” to “n”, stored in the scanner status message group memory region 34a1. The main controller 31 makes a judgment at step S22 as to whether the corresponding status message STs is retrieved or not.
Where making a judgment that the corresponding status message STs is retrieved, the main controller 31 displays the retrieved status message STs in the second line of the scanner status message display region 32b1 formed at the display unit 32b in the operation panel 32 at step S23 and makes a judgment as to whether the priority PRs corresponding to the retrieved status message STs is equal to “n” at step S24.
The main controller 31 retrieves the status message STs corresponding to a status having the second highest priority PRs at step S25 where making a judgment that the priority PRs corresponding to the retrieved status message STs is not equal to “n”. The main controller 31 furthermore makes a judgment at step S26 as to whether the corresponding status message STs is retrieved or not.
The main controller 31 displays the retrieved status message STs in the third line of the scanner status message display region 32b1 at step S27 where making a judgment that the corresponding status message STs is retrieved. The main controller 31 then makes a judgment at step S28 as to whether the warning level WLs assigned to the status message STs retrieved at step S21 and/or the step S25 is equal to “one”, or namely as to existence of the status message STs having the attribute meaning the “original document unreadable” status.
Where making a judgment of nonexistence of the status message STs having the attribute meaning the “original document unreadable” status, the main controller 31 displays in the first line of the scanner status message display region 32b1 the status message STs having the priority PRs of “n+1”, or namely the status message STs indicating the “original document readable” status and completes at step S29 this sequence of operational steps. On the other hand, where making a judgment of existence of the status massage STs having the attribute meaning the “original document unreadable” status, the main controller 31 displays in the first line of the scanner status message display region 32b1 the status message STs having the priority PRs of “n+2”, or namely the status message STs indicating the “original document unreadable” status and completes at step S30 this sequence of operational steps.
Furthermore, where making a judgment that the corresponding status message STs is not retrieved at step S22, the main controller 31 clears both the second and third lines of the scanner status message display region 32b1 at step 31 and subsequently shifts this operation to step S29 to display in the first line of the scanner status message display region 32b1 the status message STs having the priority PRs of “n+1”, or namely the status message STs indicating the “original document readable” status and then completes this sequence of operational steps.
Where making a judgment that the priority PRs corresponding to the status message STs retrieved at step S24 is equal to “n”, or that the corresponding status message STs is not retrieved at step S26, the main controller 31 shifts this operation to step S32 to clear the third line of the scanner status message display region 32b, and then shifts this operation to the operational steps subsequent to step S28.
In the event of change in the status of the scanning unit 33, the scanning apparatus 30 selects, based on the operable level information, the status message to be displayed on the display unit 32b among the plurality of status messages STs stored in the NVRAM 34. That is, the scanning apparatus 30 displays in the scanner status message display region 32b1 the status message having the warning level WLs equal to “one” meaning the “original document unreadable” status in priority to the other status messages upon processing this sequence of operational steps. In a case of nonexistence of the status message as described above, the scanning apparatus 30 can display in the scanner status message display region 32b1 the status messages sequentially in the order of priority from highest to lowest. It is to be noted that the above mentioned display example of the scanner status message display region 32b1 shown in FIG. 5 shows a display example in which the message for indicating the “original document unreadable” status is displayed in the first line, and in which the message having the priority PRs of “n” and the warning level WLs equal to “zero”, for indicating the status that “the original document is stacked on the original document board” is displayed in the second line.
Next, the operational steps to be executed in the event of change in the content displayed on the printer state message display region 22b1 formed at the display unit 22b of the printing apparatus 20 are described in reference to FIG. 8.
To execute the above mentioned operational steps, the main controller 31 needs to make a confirmation as to whether the content displayed on the printer state message display region 22b1 formed at the display unit 22b of the printing apparatus 20 changes or not. Such forms is assumed as a method for the above confirmation, that the main controller 31 periodically makes an inquiry to the main controller 21 of the printing apparatus 20 through the local interfaces 36, 27 at predetermined time interval, or that the main controller 21 of the printing apparatus 20 notifies the main controller 31 through the local interfaces 27, 36 in the event of change in the content displayed on the printer status message display region 22b1 formed at the display unit 22b of the printing apparatus 20. With the image forming system 10, either of those above described forms can be used as a method for making a confirmation as to whether the content displayed on the printer state message display region 22b1 formed at the display unit 22b of the printing apparatus 20 changes or not. In the below described description in reference to FIG. 8, such a confirmation is to be made using either of those above forms, that the content displayed on the printer state message display region 22b1 formed at the display unit 22b of the printing apparatus 20 has changed.
First, the main controller 31 operates as an operable level information retrieving section to retrieve the operable level information of the printing apparatus 20 where making a confirmation that the content displayed on the printer state message display region 22b1 formed at the display unit 22b of the printing apparatus 20 has changed. That is, the main controller 31 makes an inquiry at step S41 as shown in FIG. 8 to the main controller 21 through the local interfaces 36, 27, as to whether the status message STp having the warning level WLp equal to “one”, or namely the status message STp having the attribute meaning the “unprintable” status, exists among the status messages STp displayed on the display unit 22b. 
Where making a judgment, as a result of the above inquiry, that the status message STp having the warning level WLp equal to “one” exists among the status messages STp displayed on the display unit 22b, the main controller 31 shifts the operation to step S43 to display in the first line of the printer status message display region 32b2 the status message STsp having the status message number equal to “two” stored in the printer status message group memory region 34a2, or namely the status message STsp indicating the “unprintable” status. The main controller 31 subsequently displays in the second line of the printer status message display region 32b2 the status message STsp having the status message number equal to “three” stored in the printer status message group memory region 34a2, or namely the status message STsp indicating the status that “a confirmation as to the status of the printing apparatus 20 is required” and completes this sequence of operational steps at step S44.
On the other hand, where making a judgment that the status message STp having the warning level WLp equal to “one” does not exist among the status messages STp displayed on the display unit 22b, the main controller 31 shifts the operation to step S45 to display in the first line of the printer status message display region 32b2 the status message STsp having the status message number equal to “one” stored in the printer status message group memory region 34a2, or namely the status message STsp indicating the “printable” status. The main controller 31 subsequently clears the second line of the printer status message display region 32b2 and completes this sequence of operational steps at step S46.
In a case where a status displayed on the printer status message display region 22b1, formed at the display unit 22b of the printing apparatus 20 changes, the scanning apparatus 30 selects, based on such operable level information of the printing apparatus 20 as retrieved from the printing apparatus, the status message to be displayed on the display unit 32b among the plurality of status messages STsp stored in the NVRAM 34 upon processing this sequence of operational steps, thereby being able to display on the printer status message display region 32b2 the status message corresponding the content displayed on the printer status message display region 22b1. It is to be noted that the above mentioned display example of the printer status message display region 32b2 shown in FIG. 5 shows a display example in which both of the status message corresponding to the status message having the warning level WLp equal to “one” in the display example of the printer status message display region 22b1, shown in FIG. 3 as described above, or namely the status message for indicating the “unprintable” status and the status message for indicating the status that “a confirmation as to the status of the printing apparatus 20 is required”.
As described above, the image forming system 10 described as the first embodiment is focused on operating characteristics of the user in using the copying function resulted from connection of the printing apparatus 20 and the scanning apparatus 30 which are both operated independently, and thus displays based on the operable level information the status message for indicating whether the printing function at the printing apparatus 20 is available or not in addition to the status message of the scanning apparatus 30 on the display unit 32b at the operation panel 32 formed at the scanning apparatus 30. Consequently, with the image forming system 10, the user having intention of using the copying function can make a judgment so easily as to whether the copying function is presently available or not. Furthermore, it is only necessary to display the status message for indicating whether the printing function at the printing apparatus 20 is available or not as the status message of the printing apparatus 20 to be displayed on the display unit 32b on the operation panel 32 formed to the scanning apparatus 30, so that it is unnecessary to form to the scanning apparatus 30 the display region for displaying the status message for indicating whether the printing function at the printing apparatus 20 is available or not, to store all the status messages to be displayed on the display unit 22b of the printing apparatus 20 in the scanning apparatus 30, nor to complicate the structure to display the pictorial symbols such as, e.g., icons or the like, corresponding to the statuses respectively, and thus the cost reduction can be intended. Therefore, the image forming system 10 can meet flexibly the specification change of each of those printing apparatus 20 and scanning apparatus 30 without limited by combination of those.
The image forming system as the third embodiment is described next.
The image forming system as the second embodiment does not operate both of the printing apparatus 20 and the scanning apparatus 30, not likewise the image forming system 10 as the first embodiment, but is structured upon connecting the independently inoperable scanning apparatus as an option unit to the independently operable printing apparatus. In the description for the second embodiment, therefore, substantially the same structures as those in the first embodiment are assigned with the same reference numbers as in the first embodiment, and for the sake of simplicity, those duplicated descriptions are omitted.
The image forming system described as the second embodiment is structured as shown in FIG. 9. That is, with this image forming system 50, a independently inoperable scanning apparatus 60 is connected as the option unit in a detachable and attachable manner to the independently operable printing apparatus 20.
The scanning apparatus 60 has such a structure that all of the main controller 31, the NVRAM 34, and the memory 35 are removed from the scanning apparatus 30 as shown in FIG. 1. That is, the scanning apparatus 60 has an operation panel 62 serving as a user interface for implementing various types of input operation and display, a scanning unit 63 serving as an image reading section for reading optically the image on the original document, and a local interface 66 serving as an interface section for connecting the scanning apparatus 60 to the printing apparatus 20. Among those, the operation panel 62 has both an operation input unit 62a composed of operating elements such as, e.g., various buttons, switches, or the like, for executing the scanning function at the scanning apparatus 60 or the copying function upon combination of the scanning apparatus 60 and the printing apparatus 20 and a display unit 62b serving as a display section for displaying the status of the scanning function or the printing function, the operational status, or the other various information to be indicated.
The scanning apparatus 60 as described above is connected to the printing apparatus 20 through the local interface 66 and structured to read optically such the image on the original document as printed on the predetermined recording medium such as, e.g., the recording paper or the like, based on the control by the main controller 21 of the printing apparatus 20. That is, the printing apparatus 20 stores in the NVRAM 24 various programs for controlling the operation of the scanning function at the scanning apparatus 60 or the copying function upon combination of the scanning apparatus 60 with the printing apparatus 20, and thus is provided with the scanning function at the scanning apparatus 60 or the copying function upon combination of the scanning apparatus 60 with the printing apparatus 20 in addition to the printing function by execution of those programs by the main controller 21.
With the image forming system 50 as described above, the printing apparatus 20 is constituted upon forming in the NVRAM 24 the status message memory 24a for storing the status message to be displayed on the display units 22b, 62b for reporting the statuses of the printing apparatus 20 and the scanning apparatus 30, as shown in FIG. 10. This status message memory 24a is formed with a scanner status message group memory region 24a2 substantially the same as the above described scanner status message group memory region 24a1 for storing the group of messages for indicating the statuses generated at the scanning unit 63 of the scanning apparatus 60 and a second printer status message group memory region 24a3 substantially the same as the above described printer status message group memory region 34a2 for storing the group of messages for indicating the statuses generated at the printing unit 23, other than the first printer status message group memory region 24a1 for storing the group of messages for indicating the statuses generated at the printing unit 23.
That is, the printing apparatus 20 utilizes as the content displayed on the display unit 22b the status message STp stored in the first printer status message group memory region 24a1 whereas utilizing as the content displayed on the display unit 62b both the status message STs stored in the scanner status message group memory region 24a2 and the status message STsp stored in the second printer status message group memory region 24a3.
With the image forming system 50, in the event of change in the status of the printing unit 23, the status display operation is implemented to the display unit 22b on the operation panel 22 upon implementation of the sequence of operational steps such as shown in FIG. 6 as described above based on the control by the main controller 21, thereby displaying the status such as shown in FIG. 3 as described above. With the image forming system 50, in the event of change in the status of the scanning unit 63, the status display operation is implemented to the display unit 62b on the operation panel 62 upon making the sequence of operational steps such as shown in FIG. 7 as described above based on the control by the main controller 21, thereby displaying the status such as shown in FIG. 5 as described above. Furthermore, with the image forming system 50, in the event of change in the content displayed on the printer status message display region 22b1 formed at the display unit 22b of the printing apparatus 20, the status display operation is implemented to the display unit 62b on the operation panel 62 upon implementation of substantially the same sequent operational steps as those such as shown in FIG. 8 as described above, thereby displaying the status such as shown in FIG. 5 as described above. With the image forming system 50, it is to be noted that it is unnecessary to make an inquiry to the other main controllers to implement the operational steps such as shown in FIG. 8, nor to implement the operation at step S41 since the image forming system 50 has the single main controller.
As described above, the image forming system 50 described as the second embodiment of the invention displays based on the operable level information the status message indicating whether the printing function at the printing apparatus 20 is available or not in addition to the status message of the scanning apparatus 60 on the display unit 62b on the operation panel 62 formed to the scanning apparatus 60 to be connected as the option unit in a detachable and attachable manner to the independently operable printing apparatus 20. Consequently, with the image forming system 50, the user having intention of using the copying function can make a judgment so easily as to whether the copying function is presently available or not. Furthermore, it is only necessary to display the status message for indicating whether the printing function at the printing apparatus 20 is available or not as the status message of the printing apparatus 20 to be displayed on the display unit 62b on the operation panel 62 formed to the scanning apparatus 60, so that it is unnecessary to form to the scanning apparatus 60 the display region for displaying the status message for indicating whether the printing function at the printing apparatus 20 is available or not, to store all the status messages to be displayed on the display unit 22b of the printing apparatus 20 in the scanning apparatus 60, nor to complicate the structure to display the pictorial symbols such as, e.g., icons or the like, corresponding to the statuses respectively, and thus the cost reduction can be intended. Therefore, the image forming system 50 can meet flexibly the specification change for each of those printing apparatus 20 and scanning apparatus 60 without limited by combination of therebetween.
The image forming apparatus as the third embodiment is described next.
The image forming apparatus as the third embodiment is not structured upon connecting the printer apparatus structured as a separated apparatus and the scanning apparatus, not likewise the image forming system 10 described as the first embodiment nor the image forming system 50 described as the second embodiment, but structured as a united apparatus for realizing combined functions of the printing function and the scanning function. In the description for the third embodiment, therefore, substantially the same structures as those in the first and second embodiments are assigned with the same reference numbers as in the first and second embodiments, and for the sake of simplicity, those duplicated descriptions are omitted.
The image forming apparatus described as the third embodiment is composed as shown in FIG. 11. That is, a image forming apparatus 100 has a main controller 101 serving as a controlling section for controlling the printing apparatus 100 comprehensively, an operation panel 102 serving as a user interface for implementing various types of input operation and display, a scanning unit 103 serving as an image reading section for reading optically the image on the original record, a printing unit 104 serving as an image forming section for forming the image, an NVRAM 105 serving as a storing section for storing various programs for controlling the operation of the scanning function, the printing function, and the copying function at the image forming apparatus 100, a memory 106 for storing various information, and a network interface 107 for connecting the image forming apparatus 100 to the network 40 connected to an external apparatus such as, e.g., a host computer, or the like. The operation panel 102 among those has both an operation input unit 102a composed of operating elements such as, e.g., various buttons, switches, or the like, for executing the scanning function, the printing function, and the copying function at the image forming apparatus 100 and a display unit 102b for displaying various information to be indicated such as, e.g., conditions or operational statuses of those functions, or the like.
The image forming apparatus 100 as described above operates the scanning unit 103 based on the control by the main controller 101 to the read optically the original document image printed on the predetermined recording medium such as, e.g., the recording paper or the like whereas operating the printing unit 104 to form the image on the predetermined recording medium such as, e.g., the recording paper or the like. Furthermore, the printing unit 104 forms on the recording medium such the image data of the image on the original document as read from the predetermined recording sheet so that the image forming apparatus 100 realizes the copying function.
The image forming apparatus 100 as described above is constituted upon forming in the NVRAM 105 a status message memory 105a for storing the status message to be indicated on the display unit 102b for reporting the status of the image forming apparatus 100. The status message memory 105a is formed with both of a scanner status message group memory region 105a1, substantially the same as the above described scanner status message group memory regions 34a1, 24a2 for storing the group of messages for indicating the statuses generated at the scanning unit 103 and a printer status message group memory region 105a2 substantially the same as the above described printer status message group memory region 24a1 for storing the group of messages for indicating the statuses generated at the printing unit 104. The image forming apparatus 100 reads based on the control by the main controller 101, the status message to be reported from the various status messages STs stored in the scanner status message group memory unit 105a1, thereby displaying the read status message on the scanner status message display region 102b1 formed at the display unit 102b on the operation panel 102, as shown in FIG. 13. Furthermore, the image forming apparatus 100 reads based on the control by the main controller 101, the status message to be reported from the various status messages STp stored in the printer status message group memory unit 105a2, thereby displaying the read status message on the printer status message display region 102b2 formed at the display unit 102b on the operation panel 102. It is to be noted that FIG. 13 shows a display example in which three status messages are displayable at a maximum with respect to each of the statuses of the scanning unit 103 and the printing unit 104.
With the image forming apparatus 100, in the event of change in the status of the printing unit 104, the status display operation is implemented to the display unit 102b on the operation panel 102 upon implementation of the sequence of operational steps such as shown in FIG. 6 as described above based on the control by the main controller 101, thereby displaying the status message STp on the printer status message display region 102b2 as shown in FIG. 13. Furthermore, with the image forming apparatus 100, in the event of change in the status of the scanning unit 103, the status display operation is implemented to the display unit 102b on the operation panel 102 upon implementation of the sequence of operational steps such as shown in FIG. 7 as described above based on the control by the main controller 101, thereby displaying the status message STs on the scanner status message display region 102b1 as shown in FIG. 13. It is to be noted that FIG. 13 shows a display example on the scanner status message display region 102b1, in which the message for indicating “the original document readable status” is displayed on the first line, and in which the message having the priority PSs equal to “two” and the warning level WLs equal to “one” for indicating the status that “the original document gets jammed” is displayed in the second line, and in which the message having the priority PRs equal to “three” and the warning level WLs equal to “one” for indicating the status that “the original document board stacked with the original document is open” is displayed in the third line. FIG. 13 furthermore shows a display example on the printer status message display region 102b2, in which the message for indicating the “printable” status is displayed in the first line, and in which the message having the priority PRp of “m” and the warning level WLp equal to “zero” for indicating the status that “the toners are running out” is displayed in the second line.
As described above, the image forming apparatus 100 as the third embodiment divides the status information into groups by function and displays by function the status in one or plural number on the display unit 102b according to the order of priority. With image forming apparatus 100, therefore, such a case is never occurred that displayed is undesirably only the contents partial to a specific function but the status indication for the other functions. With the image forming apparatus 100, the user can make a judgment so easily as to availability for each function based on the warning level corresponding to the status message displayed on the display unit 102b. 
Finally, the image forming apparatus as the fourth embodiment is described.
In the description for the fourth embodiment, substantially the same structures as those in the first, second, and third embodiments are assigned with the same reference numbers as in those embodiments, and for the sake of and for the sake of simplicity, those duplicated descriptions are omitted.
The image forming apparatus described as the firth embodiment is composed as shown in FIG. 14. One part different from the structure of the first embodiment is that the operation panel is further formed with a priority updating mode selecting unit for selecting a mode for updating the priority of the status message. The priority updating mode selecting unit is composed of a printer message priority updating mode selecting unit 22c and a scanner message priority updating mode selecting unit 32c. The other different part is that the printing unit is formed with a buzzer 28 whereas the scanning unit is formed with a buzzer 38. The buzzers 28, 38 notify audibly the user about the unavailable status whereas the display unit displays the unavailable status in a case where a judgment is made that each of the printing unit and the scanning unit cannot operate normally.
The operational flow is substantially the same as that in the first embodiment, but different parts are that the user selects both the status message updating modes of the printing unit and the scanning unit before operation and that the buzzers notify audibly the user about the unavailable status whereas the display unit displays the unavailable status in a case where a judgment is made that each of the printing unit and the scanning unit cannot operate normally.
Herein, the status message updating mode of the printing unit is explained as an example of this embodiment. When the user presses an updating button on the printer status message updating mode selecting unit 22c, a screen as shown in FIG. 15 is displayed. At this time, the mode for updating the priority of the printer status message is selected between an immediate interruption mode #1 and an interruption with a predetermined waiting time mode #2. Where the user selects the immediate interruption mode #1 in the event of “no toner” status where the printer status message is such as shown in FIG. 17 at some point, for example, the main controller 21 updates the priority of each status message stored in the printer status message group memory region as shown in FIG. 2 to display the message indicating “no toner” status. On the other hand, where the user selects the interruption with a predetermined waiting time mode #2, the main controller 21 updates the priority of each status message in reference to an updating time corresponding to each printer status message previously set, such as shown in FIG. 17. For example, where the printer status massage is such as shown in FIG. 17 at some point, since the updating time interval for “no toner” message shown in FIG. 18 is set to 2s, the main controller 21 does not update immediately the priority of each message stored in the printer status message group memory region but updates for the first time each of the priorities of messages stored in the printer status message group memory region to the priorities as shown in FIG. 2 after the interval of 2s passes.
In FIG. 18, an updating time period 10s corresponding to the message indicating the status that “the toners is running out soon” is set longer than the updating time period 2s corresponding to “no toner” message. This is because the printing operation can be implemented normally even where the waiting time is prolonged not to implement the updating operation in the event of the message indicating the status that “the toner is running out soon”. In FIG. 18, the updating time interval corresponding to the fuser error is set to 0s. Therefore, the updating operation is implemented immediately even where the priority updating mode is in the interruption with a predetermined waiting time mode #2 when the error is occurred during the operation of the fuser. The updating time interval corresponding to the scanner status message is shown in FIG. 19. In FIG. 19, the updating time interval corresponding to a lamp error is set to 0s. Thus, the updating operation can be implemented immediately even in the interruption with a predetermined waiting time mode #2 where the error is caused during the operation of the lamp. FIG. 19 shows a priority updating time interval corresponding to the scanner status message. In FIG. 19, the updating time interval corresponding to the fuser error is set to 0s. That is, the updating operation is immediately implemented even where the priority updating mode is in the interruption with a predetermined waiting time mode #2 in the event of the lamp error.
The priority updating mode of the scanner status message is set as described above in the scanning unit. Substantially the same operational flow as in the first embodiment is implemented subsequently. However, where the printing unit enters in the “unprintable” mode as shown in FIG. 3 during the operation, the display unit displays the unprintable status to the user visually while the buzzer unit 28 notifies the user about the unprintable status audibly. Where the scanning unit enters in the “unreadable” mode, the display unit also displays the unreadable status to the user visually while the buzzer unit 38 notifies the user about the unreadable status audibly.
In addition to the effects of the first embodiment, this embodiment has the effect that usability of this system can be improved for the user upon setting with the priority updating selecting mode the status message priority of each of the printing unit and the scanning unit depending on the use environment. Furthermore, the usage can be further improved upon displaying the unavailable status on the display unit to the user visually and upon notifying the unavailable status to the user audibly using the buzzer unit 38 audibly in a case of both the printing unit and the scanning unit in the unavailable mode.
In this embodiment, both the status message priority updating mode selecting units of the printing unit and the scanning unit and the buzzer unit are added to the structure of the first embodiment but can be added to that of the second embodiment for carrying out this invention.
It is to be noted that this invention is not limited to the above described embodiments. In description for those embodiments, for example, two values, i.e., “zero” and “one” are used as the warning level corresponding to the status message of the printing apparatus to display at the scanning apparatus the status indicating whether the printing apparatus is available or not, but the third level warning level may be set to indicate such the status of the printing apparatus as possibly resulting in quality deterioration in the formed image, for example, the status that “the toners are running out”, or that “a life of a photosensitive drum is expiring”, and the information of those statuses may be reported to the scanning apparatus to display the status such as, e.g., “printable status (warning-image quality) as the status having the third warning level of the printing apparatus on the display unit of the scanning apparatus.
Furthermore, in the description for those embodiments, each display unit is formed with the display region in the plurality of lines, but this invention is not limited to the above display forms and the display region in an arbitrary form.
As described above, it is obvious that this invention can be arbitrarily modified without departing from the scope of this invention.
The foregoing description of preferred embodiments of the invention has been presented for purposes of illustration and description, and is not intended to be exhaustive or to limit the invention to the precise form disclosed. The description was selected to best explain the principles of the invention and their practical application to enable others skilled in the art to best utilize the invention in various embodiments and various modifications as are suited to the particular use contemplated. It is intended that the scope of the invention should not be limited by the specification, but be defined by the claims set forth below.
