Patent Description:
Embodiments described herein relate generally to an image forming device and a control method.

In the related art, in an image forming device, an abnormality may occur in image quality of an image printed on a sheet, such as an image being printed with a shift. When such an image quality abnormality occurs, appropriate processing such as cleaning and part replacement is required according to the type of the image quality abnormality.

In general, since a user may not be familiar with the various types of image quality abnormalities, the user may not know how to properly address the abnormality. Therefore, the user makes an inquiry to a serviceman, but the user cannot appropriately notify the serviceman of the image quality abnormality when the user does not know the type of the image quality abnormality. When the serviceman cannot specify the type of the image quality abnormality, the serviceman cannot visit the user with a part necessary for processing the image quality abnormality in some cases. In this case, since the serviceman needs to visit again, service cost of the serviceman increases. In addition, the user experiences an extended delay before the image forming device can be used.

Therefore, the user is conceived to transmit an image with the image quality abnormality to the serviceman. In this case, although the serviceman can specify the type of the image quality abnormality, a security problem may occur in the transmission of the image.

Based on such a background, several techniques of specifying the type of an image quality abnormality without transmitting an image with the image quality abnormality to a serviceman are proposed. Examples of such a technique include an image forming device that displays a plurality of images of an example of occurrence of an image quality abnormality and allows a user to select one of the images. In addition, an image forming device that allows a user to input the type of an image quality abnormality and position information of occurrence of the image quality abnormality is known.

However, in the above technique, an input operation of the user may become complicated depending on the type of the image quality abnormality.

In addition, <CIT> (<NUM>-<NUM>-<NUM>), deals with determining the number of image inspection charts to be output by using image feature information of an output product determined to have an abnormal image.

In the image forming device according to an embodiment, a user can easily input information relating to an image quality abnormality. Hereinafter, the image forming device according to the embodiment will be described in detail.

<FIG> is a side view of an image forming device <NUM> according to an embodiment. In <FIG>, the image forming device <NUM> includes an image formation control unit <NUM> (e.g., a controller) and a printer unit <NUM> (e.g., a printer). The image formation control unit <NUM> controls the printer unit <NUM> and the like. The image formation control unit <NUM> controls conveyance of a medium, such as a sheet of paper or plastic film, (hereinafter, referred to as a "sheet") in the printer unit <NUM>. The control of the conveyance of the sheet is to control conveyance timing of the sheet, a stop position of the sheet, a conveyance speed of the sheet, and the like.

A sheet feeding cassette <NUM> stores the sheet. For example, a material such as paper or a plastic film is used for the sheet.

The printer unit <NUM> is an example of the image forming unit. The printer unit <NUM> performs an image forming operation. For example, the printer unit <NUM> forms an image indicated by the image data on the sheet. In the following description, the formation of an image on a sheet is also referred to as printing. The printer unit <NUM> includes an intermediate transfer belt <NUM>. The printer unit <NUM> supports the intermediate transfer belt <NUM> by a driven roller <NUM>, a backup roller <NUM>, and the like. The printer unit <NUM> rotates the intermediate transfer belt <NUM> in a direction of an arrow m.

The printer unit <NUM> includes four sets of image forming stations <NUM>, <NUM>, <NUM>, and <NUM>. The image forming stations <NUM>, <NUM>, <NUM>, and <NUM> are used for forming images of yellow (Y), magenta (M), cyan (C), and black (K), respectively. The image forming stations <NUM>, <NUM>, <NUM>, and <NUM> are arranged below the intermediate transfer belt <NUM> along a rotation direction of the intermediate transfer belt <NUM>.

Hereafter, the image forming station <NUM> for yellow (Y) of the image forming stations <NUM>, <NUM>, <NUM>, and <NUM> will be described as an example. Since the image forming stations <NUM>, <NUM>, and <NUM> have the same configuration as that of the image forming station <NUM>, a detailed description thereof will be omitted.

The image forming station <NUM> includes an electrostatic charger <NUM>, an exposure scanning head <NUM>, a developing device <NUM> (e.g., a developer), and a photoreceptor cleaner <NUM>. The electrostatic charger <NUM>, the exposure scanning head <NUM>, the developing device <NUM>, and the photoreceptor cleaner <NUM> are arranged around a photoreceptor drum <NUM> rotating in a direction of an arrow n.

The image forming station <NUM> includes a primary transfer roller <NUM>. The primary transfer roller <NUM> faces the photoreceptor drum <NUM> via the intermediate transfer belt <NUM>.

In the image forming station <NUM>, the photoreceptor drum <NUM> is charged by the electrostatic charger <NUM>, and then exposed by the exposure scanning head <NUM>. The image forming station <NUM> forms an electrostatic latent image on the photoreceptor drum <NUM>. The developing device <NUM> develops the electrostatic latent image on the photoreceptor drum <NUM> using a two-component developer formed of a toner and a carrier.

The primary transfer roller <NUM> primarily transfers a toner image formed on the photoreceptor drum <NUM> onto the intermediate transfer belt <NUM>. The image forming stations <NUM>, <NUM>, <NUM>, and <NUM> form a color toner image on the intermediate transfer belt <NUM> by the primary transfer roller <NUM>. The color toner image is formed by sequentially superimposing toner images of yellow (Y), magenta (M), cyan (C), and black (K). The photoreceptor cleaner <NUM> removes the toner remaining on the photoreceptor drum <NUM> after the primary transfer.

The printer unit <NUM> includes a secondary transfer roller <NUM>. The secondary transfer roller <NUM> faces the backup roller <NUM> via the intermediate transfer belt <NUM>. The secondary transfer roller <NUM> collectively and secondarily transfers the color toner images on the intermediate transfer belt <NUM> to the sheet. In the following description, the term "toner image" may be either the color toner image or a toner image of only one color. The toner image may be a toner image using a decolorable toner.

A conveyance path <NUM> is a conveyance path from a merging portion <NUM> to a branch portion <NUM>. A conveyance path <NUM> is a conveyance path that passes through an inside of a duplex printing device <NUM>, and is a conveyance path from the branch portion <NUM> to the merging portion <NUM>. The conveyance path <NUM> is a conveyance path from the branch portion <NUM> to a sheet discharging tray <NUM>.

A leading end of a sheet, which is picked up from the sheet feeding cassette <NUM> or a manual feeding tray <NUM>, abuts against a portion where two stopped registration rollers <NUM> are in contact with each other. An inclination of the sheet abutting against the registration rollers <NUM> is corrected. The image formation control unit <NUM> starts rotation of the registration rollers <NUM> in accordance with a position of the toner image on the rotating intermediate transfer belt <NUM> to move the sheet to a position of the secondary transfer roller <NUM>. The image formation control unit <NUM> secondarily transfers the toner image formed on the intermediate transfer belt <NUM> onto the sheet by the secondary transfer roller <NUM>. The image formation control unit <NUM> conveys the sheet to the conveyance path <NUM> and fixes the toner image to the sheet (e.g., on a front side of the sheet) by a fixing device <NUM> (e.g., a fixer, a heater, etc.) to form an image. The image formation control unit <NUM> conveys the sheet on which the image is formed to the conveyance path <NUM> to discharge the sheet.

For double-sided printing, the image formation control unit <NUM> conveys a sheet having an image formed on a front surface to the conveyance path <NUM>. After the entire sheet passes through the branch portion <NUM> (e.g., in a forward direction), the image formation control unit <NUM> causes the sheet to switch back (e.g., move in a reverse direction), and conveys the sheet to the conveyance path <NUM>. Thereafter, the image formation control unit <NUM> conveys the sheet to the merging portion <NUM> via the conveyance path in the duplex printing device <NUM>, and conveys the sheet to the conveyance path <NUM> via the registration rollers <NUM>. Then, the image formation control unit <NUM> fixes a toner image by the fixing device <NUM> to form an image on a back surface of the sheet. The image formation control unit <NUM> conveys the sheet having the image formed on a back surface to the conveyance path <NUM> to discharge the sheet.

Before the image formed in the printer unit <NUM> is secondarily transferred by the secondary transfer roller <NUM>, an electrostatic latent image is formed on the photoreceptor drum <NUM> by the exposure scanning head <NUM>. The electrostatic latent image formed on the photoreceptor drum <NUM> is primarily transferred onto the intermediate transfer belt <NUM> as a toner image. Further, the toner image primarily transferred onto the intermediate transfer belt <NUM> is secondarily transferred onto a radio tag sheet conveyed to a position of the registration rollers <NUM>.

Next, a function block diagram of the image forming device according to the embodiment is described with reference to <FIG>.

In <FIG>, the image forming device <NUM> includes the image formation control unit <NUM>, a control panel <NUM>, and the printer unit <NUM>.

The control panel <NUM> (e.g., a user interface) includes input keys (e.g., an input) and a display unit (e.g., a display, an output). For example, the input keys receive an input from the user. For example, the display unit is a touch panel (e.g., a touchscreen). The display unit receives the input from the user, and displays the input to the user. For example, the control panel <NUM> displays an item relating to an operation of the image forming device <NUM> on the display unit in a settable manner. The control panel <NUM> notifies the image formation control unit <NUM> of the item set by the user (e.g., a user input).

The image formation control unit <NUM> includes a calculation device <NUM> (e.g., a processor) and a storage device <NUM> (e.g., a memory). The calculation device <NUM> controls the control panel <NUM> and the printer unit <NUM> in accordance with an image processing program stored in the storage device <NUM>.

The calculation device <NUM> is, for example, a central processing unit (CPU), an application specific integrated circuit (ASIC), and the like. The storage device <NUM> is a read only memory (ROM), a random access memory (RAM), a hard disk drive (HDD), a solid state drive (SSD), and the like.

A communication unit <NUM> (e.g., a network interface, a communication interface, etc.) controls overall communication of the image forming device <NUM>. For example, the communication unit <NUM> performs communication via a local area network (LAN) or the Internet. The communication unit <NUM> receives printing data (for example, data described in a page description language) indicating an image to be printed from a host such as a personal computer (PC), and stores the received printing data in the storage device <NUM>.

An image data loading unit <NUM> determines printing conditions based on the printing data that is received by the communication unit <NUM> and stored in the storage device <NUM> to load the printing data into data (for example, raster data) that can be printed by the printer unit <NUM> and store the data in the storage device <NUM>.

The printer unit <NUM> includes the fixing device <NUM>, the secondary transfer roller <NUM>, the developing device <NUM>, and the like described above. <FIG> shows only a part of a configuration of the printer unit <NUM> shown in <FIG>. The printer unit <NUM> forms an image on a sheet based on the data that is stored in the storage device <NUM> by the image data loading unit <NUM>.

Next, an example of an image quality abnormality will be described. In the following description, an image to be printed on a sheet by the printer unit <NUM> is referred to as a printing image (e.g., a desired image). An image actually printed on a sheet is referred to as a sheet image (e.g., a printed image or a resultant image). Specifically, the printing image is an image indicated by the printing data described above.

<FIG> and <FIG> are diagrams each illustrating an example of a hot offset that is one of image quality abnormalities. The hot offset is an image quality abnormality that an image is stained by a toner moving to rollers constituting the fixing device <NUM>.

<FIG> is a diagram illustrating the printing image. The printing image includes an image <NUM>. The image <NUM> is an image indicating a character string "user print image". <FIG> is a diagram illustrating a sheet image in which the hot offset occurs. The sheet image includes an image <NUM> and an image <NUM>.

The image <NUM> is a hollowed or otherwise faded image obtained by transferring a part of the "user print image" to the rollers constituting the fixing device <NUM>. In addition, the image <NUM> is an image obtained by adhering the toner transferred to the fixing device <NUM> to a latter half of the sheet to pass the fixing device <NUM> after the image <NUM> passes through the fixing device <NUM>. In this way, the hot offset is an image quality abnormality that the toner is adhered to a position shifted in the conveyance direction of the sheet on which the image is printed.

<FIG> and <FIG> are diagrams each illustrating an example of a ghost that is one of image quality abnormalities. The ghost is an image quality abnormality that an electrostatic latent image indicating the printing image remains on the photoreceptor drum <NUM> and unevenness occurs in an image printed thereafter due to the electrostatic latent image. The unevenness is often observed when the image printed thereafter is a halftone image (e.g., thin).

<FIG> is a diagram illustrating a printing image. The printing image includes an image <NUM> and an image <NUM>. The image <NUM> is an image indicating the character string "user print image". The image <NUM> is a solid image.

<FIG> is a diagram illustrating a sheet image in which the ghost occurs. <FIG> includes an image <NUM> and an image <NUM>. The image <NUM> is printed as the image <NUM> without any abnormality. On the other hand, the character string "user print image" is printed as unevenness on an image <NUM>. In this way, the ghost is an image quality abnormality that unevenness occurs at a position shifted in a conveyance direction of a medium on which an image is printed.

Both the hot offset and the ghost are image quality abnormalities that a certain image appears again in the same size. Therefore, input of the image itself by a user is troublesome and difficult as described in the related art. In addition, even if the user simply designates a position, the type of the abnormality cannot be notified to a serviceman.

Next, a user interface used for the user to input information relating to the image quality abnormality will be described. In the description of the user interface, a sheet image in which a ghost occurs is used as an example. <FIG>, and <FIG> are diagrams each illustrating a screen displayed on the display unit of the control panel <NUM>.

<FIG> is a diagram illustrating an example of a selection screen <NUM>. The selection screen <NUM> is a screen for the user to select a printing image corresponding to a sheet image with an image quality abnormality. The image formation control unit <NUM> stores the printing image in the storage device <NUM> every time printing is performed. In addition, the image formation control unit <NUM> stores, together with the printing image, an image forming condition when the printing image is printed in the storage device <NUM> in association with the printing image. The image forming condition will be described below in detail.

A printing image is displayed on the selection screen <NUM> for each job. In <FIG>, printing images of two jobs of a job A and a job B are displayed. The "user print image", "A", "B", and the like in the printing image shown in <FIG> are images to be printed on the sheet, not character strings, codes, and the like for illustration.

As an example, the job A is a job in which four pages are printed. Printing images <NUM>, <NUM>, <NUM>, and <NUM> are printing images in the job A. The printing image <NUM> is a printing image showing page <NUM>, the printing image <NUM> is a printing image showing page <NUM>, the printing image <NUM> is a printing image showing page <NUM>, and the printing image <NUM> is a printing image showing page <NUM>.

As an example, the job B is a job in which one page is printed. A printing image <NUM> is a printing image in the job B. The printing image <NUM> is a printing image showing page <NUM>.

As shown in the job A, a printing image when the number of pages that are not fit in the selection screen <NUM> is printed can be displayed by a horizontal scroll by an operation of the user. In addition, a printing image of a job subsequent to the job B (e.g., a job C) can be displayed by a vertical scroll by an operation of the user. The user selects a printing image corresponding to the sheet image with an image quality abnormality in the selection screen <NUM>.

When the printing image is selected, a region designation screen is displayed. <FIG> is a diagram illustrating an example of a region designation screen <NUM>. The region designation screen <NUM> is a screen for the user to designate a region in the printing image. By way of example, the user may designate both a shape and a location of the region. The region here is a region containing an image in the printing image corresponding to an image with an image quality abnormality in the sheet image. In the following description, the image in the printing image corresponding to the image with an image quality abnormality is referred to as an "abnormal original image".

Examples of a method for designating a region include a method in which the user traces an image including the abnormal original image, on a display device with a finger, a stylus pen, and the like. As described above, since a touch panel is provided on the display device, the image formation control unit <NUM> can acquire a trajectory traced with a finger and the like. The designated designation region is displayed as a region <NUM> as illustrated in <FIG> (e.g., by displaying a boundary of the designated designation region as a dashed line). When the designation of the designation region is completed, the user touches a designation completion button <NUM>. The user preferably designates the designation region by drawing a closed curve, but when the trajectory traced by the user is not a closed curve, the image formation control unit <NUM> interpolates two endpoints at both ends of the trajectory by a straight line to form a closed curve.

When the designation completion button <NUM> is touched, a superimposition position designation screen is displayed. <FIG> is a diagram illustrating an example of a superimposition position designation screen <NUM>. The superimposition position designation screen <NUM> is a screen for the user to designate a superimposition position at which a same-shape region <NUM> (e.g., an abnormality region containing the abnormality) having the same shape as that of the designation region designated on the region designation screen <NUM> is superimposed on the printing image (e.g., the same-shape region and the designation region have a common shape). The superimposition position designation screen <NUM> illustrated in <FIG> shows a superimposition position designation screen after the superimposition position is designated.

Examples of a method for designating a superimposition position include a method in which a user touches a superimposition position or drags the region <NUM> to the superimposition position. The user designates a superimposition position at which a hot offset or a ghost occurs. When the superimposition position is designated, the image formation control unit <NUM> visually represents the abnormality displaying an in-region image (e.g., the abnormality) drawn in the designation region in a same-shape region <NUM> superimposed at the superimposition position. Accordingly, as illustrated in <FIG>, the abnormal original image is displayed on the printing image.

Further, a color and transparency can be designated on the superimposition position designation screen <NUM>. The color is a color of the in-region image that is displayed in the region superimposed at the superimposition position. That is, the color is a color of the in-region image actually printed as the hot offset or the ghost. The user can select or not select a color by a corresponding color selection button <NUM>. The user can select any one of yellow (Y), magenta (M), cyan (C), black (B), and white (W) as the color. When the color is not selected, the user selects "remain". As an example, each color of YMCKW is selectable in <FIG>, but the selectable color may be any color.

The transparency is transparency of the in-region image that is displayed in the region superimposed at the superimposition position. That is, the transparency is transparency of the in-region image actually printed as the hot offset or the ghost. The user can select either "semi-transparent" or "opaque" by a transparency button <NUM>. For example, either "semi-transparent" or "opaque" can be selected in <FIG>, but any selection method or designation method may be used, such as a method in which the transparency can be designated by a ratio (%). The color and the transparency may be optionally selected.

When the user designates the superimposition position, selects the color and the transparency, and touches a transmission button <NUM>, user designation information indicating a region designated on the region designation screen <NUM> and a superimposition position designated on the superimposition position designation screen <NUM> is transmitted to an external device, such as a server (not illustrated). The server is configured to be accessible by a serviceman (e.g., service personnel). The serviceman can view the user designation information by accessing the server.

The user designation information includes a selected color (including "remain") and transparency in addition to the region and the superimposition position. The color and the transparency may be optionally selected. When the color and the transparency are not selected, the user designation information includes information showing no selection.

In addition to the user designation information, condition information indicating the image forming condition is also transmitted. In the present embodiment, examples of the image forming condition include a transfer temperature, a life of a component (e.g., the photoreceptor drum <NUM>), a primary transfer bias voltage, and a printing direction. The transfer temperature is a temperature at which the toner image is fixed to the sheet by the fixing device <NUM>. The "life" indicates an elapsed time from a start of use of the photoreceptor drum <NUM>, the number of rotations, and the like. The primary transfer bias voltage indicates a voltage applied to the electrostatic charger <NUM>. The printing direction indicates a conveyance direction of the sheet when the printer unit <NUM> forms the printing image on the sheet. The above image forming conditions are examples, and the image forming condition is not limited to these examples.

As described above, the serviceman can view the region, the superimposition position, the color, the transparency, and the image forming condition. <FIG> is a diagram illustrating an example of a screen viewed by the serviceman. The screen is, for example, a screen displayed on a technician device, such as a personal computer (PC), smartphone, and the like.

In <FIG>, a serviceman viewing screen <NUM> includes printing direction information <NUM>, region information <NUM>, abnormal image information <NUM>, shift information <NUM>, and a column <NUM> or table of various pieces of information. The printing direction information <NUM> indicates the printing direction of the image forming conditions by an arrow The region information <NUM> indicates a region designated on the region designation screen <NUM>. The region is indicated by a solid line.

The abnormal image information <NUM> indicates the superimposition position designated on the superimposition position designation screen <NUM>. The abnormal image information <NUM> is displayed with the color selected by the color selection button <NUM> and the transparency selected by the transparency button <NUM>. In addition, the region superimposed on the superimposition position is indicated by a broken line. A shift amount indicates a shift amount (mm) of the region and the superimposition position with respect to the printing direction.

The column <NUM> of various pieces of information is a column displaying items of "ID", "user name", "color", "transparency", "transfer temperature", "life", and "primary transfer bias voltage". The "ID" is identification information that uniquely identifies the image forming device <NUM>. The "user name" indicates a name of a user of the image forming device <NUM>. The "color" indicates a color selected by the color selection button <NUM>. The "transparency" indicates transparency selected by the transparency button <NUM>. The "transfer temperature", the "life", and the "primary transfer bias voltage" are described in the image forming conditions described above.

In this way, a serviceman can obtain detailed information on an abnormality. In addition, the region information <NUM> and the abnormal image information <NUM> are displayed to the serviceman as shown in <FIG>, but contents of the image are not displayed at all, so that security can be ensured. The server or the image formation control unit <NUM> may have a function of estimating a component of the printer unit <NUM> that causes the image quality abnormality based on the shift amount, the color, and the transparency, and may display the component on the serviceman viewing screen <NUM>.

<FIG> is a flowchart illustrating a processing flow of the image forming device <NUM>. The processing is triggered by, for example, an operation of a user on the control panel <NUM>. The image formation control unit <NUM> displays a selection screen (see <FIG>) (ACT <NUM>). When the user completes the selection of the printing image (ACT <NUM>: YES), the image formation control unit <NUM> displays the region designation screen (see <FIG>) (ACT <NUM>). When the user completes the designation of the region (ACT <NUM>: YES), the image formation control unit <NUM> displays the superimposition position designation screen (see <FIG>) (ACT <NUM>).

The image formation control unit <NUM> determines whether the selection of the color is completed by the color selection button <NUM>(ACT <NUM>). When the selection of the color is not completed (ACT <NUM>: NO), the image formation control unit <NUM> proceeds to ACT <NUM>. On the other hand, when the selection of the color is completed (ACT <NUM>: YES), the image formation control unit <NUM> temporarily stores information indicating the selected color in the storage device <NUM> (ACT <NUM>).

The image formation control unit <NUM> determines whether the selection of the transparency is completed by the transparency button <NUM>(ACT <NUM>). When the selection of the transparency is not completed (ACT <NUM>: NO), the image formation control unit <NUM> proceeds to ACT <NUM>. On the other hand, when the selection of the transparency is completed (ACT <NUM>: YES), the image formation control unit <NUM> temporarily stores information indicating the selected transparency in the storage device <NUM> (ACT <NUM>).

The image formation control unit <NUM> determines whether the designation of the superimposition position is completed (ACT <NUM>). When the designation of the superimposition position is not completed (ACT <NUM>: NO), the image formation control unit <NUM> proceeds to ACT <NUM>. On the other hand, when the designation of the superimposition position is completed (ACT <NUM>: YES), the image formation control unit <NUM> temporarily stores information indicating the designated superimposition position in the storage device <NUM> (ACT <NUM>).

The image formation control unit <NUM> determines whether the transmission button <NUM> is touched (ACT <NUM>). When the transmission button <NUM> is not touched (ACT <NUM>: NO), the image formation control unit <NUM> proceeds to ACT <NUM>. On the other hand, when the transmission button <NUM> is touched (ACT <NUM>: YES), the image formation control unit <NUM> transmits the user designation information and the image forming conditions (ACT <NUM>) and ends the processing.

The image formation control unit <NUM> refers to the information stored in the storage device <NUM> in ACTs <NUM>, <NUM>, and <NUM>, and transmits the user designation information to the above server. In addition, the image formation control unit <NUM> refers to the image forming conditions stored in the storage device <NUM> in association with the printing image selected in ACT <NUM>, and transmits the image forming conditions.

The image formation control unit <NUM> stores the color in the above ACT <NUM>, and when the display unit can perform color display, a region may be displayed with the selected color. The image formation control unit <NUM> stores the transparency in ACT <NUM>, and a region may be displayed with the selected transparency.

The information indicating the region and the superimposition position, which is transmitted as the user designation information, may be, for example, image data indicating the region and the superimposition position. Alternatively, the information may be vector data of a closed straight line indicating the region and the superimposition position.

According to the embodiment described above, since a user only needs to designate a region or a superimposition position, the user can easily input information relating to the image quality abnormality.

Claim 1:
An image forming device (<NUM>) comprising:
a printer (<NUM>) configured to form a desired image indicated by image data on a sheet;
a display configured to display the desired image; and
a controller (<NUM>) configured to:
receive a first designation, by a user, of a designation region of the desired image displayed on the display;
receive a second designation, by the user, of a superimposition position at which an abnormality region containing an abnormality is superimposed on the desired image; and
transmit user designation information indicating the designation region and the superimposition position to an external device.
