Abstract:
A method for improving human interaction with a printer and its hardcopy output. The method comprises printing a print job and placing it into an output bin followed with a pause before printing a banner page for that print job. However, this banner will not be printed if the print job is removed from the output bin before the pause concludes and thereby expedite any subsequent printing output that may follow. This allows the individual to pick up their print job immediately with out accruing the expense or waste of printing a banner sheet.

Description:
BACKGROUND OF THE INVENTION AND MATERIAL DISCLOSURE STATEMENT  
         [0001]    The present invention relates to a methodology for expediting the handling of print job output in the output bin of a printer. In particular, the present invention relates to where a shared printer places banner sheets with the desired printout in the output bin.  
           [0002]    Sharing of resources has become an integral part of the typical day-to-day business operations scenario. In particular, printers of greater cost and which offer such attributes as higher speed, better resolution or color are shared. However, this means that the printed hardcopy output in the shared resource is often provided in a limited number or even a single output bin. Most printers designed for resource sharing accommodate this problem in a few ways. Typically the printer will skew or offset entire print jobs from each other. Often a banner or header page is inserted as a separator sheet between the print jobs. Examples of this are found in U.S. Pat. No. 4,211,483 to Hannigan et al., U.S. Pat. No. 5,316,279 to Corona et al., U.S. Pat. No. 5,547,178 to Costello, and U.S. Pat. No. 5,709,374 to Taylor et al., which are herein incorporated by reference in their entirety for their teaching.  
           [0003]    Banner pages have long been associated with print jobs in shared print environments. A banner page is, typically, a printed sheet that separates one print job output from another. For example, a banner page may include the name or some other uniquely identifying feature of the user that submitted the print job, often in an eye-catching format, so that the user can easily find and separate his/her print job from the other jobs in the printer&#39;s output tray.  
           [0004]    Traditionally, the use of banner pages has been relatively narrow in scope and purpose, reflecting the capabilities and intended use of the shared printers. For example, one banner page has typically been output on top of (or in association with) each print job submitted. If multiple copies of a particular job are requested, then multiple banner pages may also be produced. Essentially, the only option available has been whether to print the banner page with the job, or not, and even that option is not adjustable by the user because it is pre-designed at the shared print server that spools the print job to the printer.  
           [0005]    The problem with banner pages of course is that they create waste. Often as soon as a print job is picked up the banner page is discarded. If only one sheet of paper needed to be printed, the addition of the banner sheet represents 50% waste. Furthermore, it&#39;s not unusual for the banner page to create some delay in the completion of a print job when the printer must receive the banner information from the server. See U.S. Pat. No. 6,075,617 to Fisher et al. which is hereby incorporated by reference in its entirety for its teaching. One example of this delay is a Xerox Document Centre ColorSeries 50 when connected to a LAN. If a user is present to retrieve their print job, they must wait for a banner to print they don&#39;t need. In addition there are consumables such as toner or ink which are also wasted with banner sheet printout.  
           [0006]    Therefore, as discussed above there exists a need for a methodology which will solve the problem of print delays due to banner sheets and the waste they create. Thus, it would be desirable to solve this and other deficiencies and disadvantages with an improved methodology.  
         SUMMARY OF THE INVENTION  
         [0007]    The present invention relates to a method for a shared printer to provide print jobs with banner pages to its output bin, comprising outputting a current print job to the output bin followed by pausing the output of a banner page for a fixed period of time. The printer shall then skip the printout of the banner page if the current print job is removed from the output bin before the fixed period of time has passed.  
           [0008]    More particularly, the present invention relates to a method for a network connected printer to provide print jobs with banner pages to its output bin, comprising outputting a current print job to the output bin followed by pausing the output of a banner page for a fixed period of time. Then sensing the output bin and skipping the printout of the banner page if the current print job is removed from the output bin before the fixed period of time has passed.  
           [0009]    Further, the present invention relates to a method for a shared printer to provide print jobs with a banner page to its output bin, comprising outputting a current print job to the output bin. Then sensing the output bin and skipping the printout of the banner page if the current print job is removed from the output bin.

     DESCRIPTION OF THE INVENTION  
       [0014]    [0014]FIG. 1 provides an ink jet printer  10 . There, it will be observed that a paper input or supply tray  12  is provided in the front, or user-facing portion,  14  of the printer  10 . The paper input tray  12  is configured to handle a substantial quantity of paper  16   a  or other medium for printing thereon. Also in the front  14  of the printer  10  is provided a paper output or collection tray  18 . The paper output tray  18  is also configured to handle a substantial quantity of paper  16   b.    
         [0015]    There are two features to be noticed with regard to the paper output tray  18 . First, an output bin sensor  20  is provided near the rear of the paper output tray  18 . Sensor  20  is provided for indication of whether the user has removed the previous page or output paper  16   b . The operation of sensor  20  may be based for example upon sensing weight, light scattering or light reflectance effects from when paper  16   b  is present or not in collection tray bin  18 . In a preferred embodiment, an inexpensive simple LED detector pair is used that can detect either a reflectance or a scattering signal. Thus both transparencies and paper can be detected. Many other arrangements will be conceivable to those skilled in the art and as such are considered within the gambit of the present invention. It should be noted for instance that there are many arrangements for providing this sensor functionality including its placement location in the output bin. For example, many printer systems already have a sensor provided at the output for the purpose of tracking paper jams. Such arrangements may be utilized with the present invention with little or even no modification as would be evident to one skilled in the art.  
         [0016]    Second, a pair of opposed output rails  22  is provided above the output tray  18 . These output rails  22  along with the platen (not visible in this view) support a sheet of paper  16   c  during the printing operation to permit the ink on the sheet  16   b  underneath to dry. At the end of the printing cycle, when the sheet  16   c  is near the front  14   a  of the paper output tray  18 , the platen pivots down, eliminating the clamping of the sheet between the platen and paper guide  27 . The sheet  16   c  then drops into the paper output tray of its own weight. Up until the completion of the printing cycle, the rear end of the paper is supported by the paper drive roller and the platen.  
         [0017]    The front portion  14  of the printer  10  is also provided with a control panel  28 , which is electrically associated with a microprocessor/controller  200  (FIG. 2) for selection of various options relating to the printing operation. Such control operations, provided by presently-available microprocessors, are well-known in the prior art.  
         [0018]    Also shown in FIG. 1 is a printhead carriage  35 , which travels on a guide rail  34  and paper guide  27 , and printhead  32  which is connected by a flexible electrical flat ribbon  36  to the microprocessor/controller  200 . The microprocessor/controller  200  controls a motor, which provides movement of the printhead carriage  35 . The printhead  32  is specifically designed for this ink-jet printer, and utilizes thermal ink-jet printing technology. However, the printer could operate with other ink-jet printheads if the printhead carriage interfaces are compatible, or with other carriage configurations. Further, reconfiguration of the printhead carriage  32  would permit the use of other ink-jet technologies, such as piezoelectric. Such reconfiguration is within the capabilities of one skilled in the art.  
         [0019]    It should be noted that while the above preferred embodiment printer is an ink jet type, that an alternative equally preferred embodiment includes a laser type printer. Further as will be apparent to those skilled in the art, the techniques taught here in the present invention will be applicable to many types of hardcopy output devices.  
         [0020]    [0020]FIG. 2 provides a concise schematical representation of a preferred embodiment. Controller  200  is coupled with output bin sensor  20 . In a preferred embodiment controller  200  polls for an indicator from sensor  20 . When sensor  20  indicates that the printout has been removed from the output bin the controller  200  executes a decision to end a counter/timer loop (if it was needed) and proceed directly to the printing of the new print job if any. As such the controller  200  may now skip directing the printer to generate a banner page or interrupt the banner sheet print if it has already begun printing.  
         [0021]    In an alternative embodiment, the signal indication of printout removal from output bin by sensor  20  is handled by the controller  200  as an interrupt.  
         [0022]    Those skilled in the art will understand what software changes are necessary for that scenario. Indeed, there are many other hardware and software specifics which will yield the same result, including for example custom logic circuits (ASIC FPGA, etc.) dedicated to implementing the logic flow discussed below.  
         [0023]    In FIG. 3, merely by way of an example, the exemplary shared user electronic printer  10  (a laser type) is shown connected into a conventional prior art inner-office or interoffice system electronic local area network (LAN)  300  with various remote user terminals (workstations)  310 , one of which is shown here in an enlarged view. Some other possible typical network system components are also illustrated and labeled.  
         [0024]    A preferred embodiment is depicted with FIG. 4. In this arrangement the printer  10  is connected to a local area network (LAN)  300  and receives print jobs from there. Printer  10  may be ink jet as above, or any type of printer suitable for connection to a LAN  300  and the handling of multi-page print jobs. At instruction block  400  the last page of a print job issues and so a command indicating that status is passed to the set pause counter block  410 . This sets and starts the increment timer block  420 . While a software timer is used here, it should be noted that in a normal LAN connected printer there is often a small delay as the data for generating the banner page (or header page) is polled from the server or over the network. This delay may be utilized instead in a preferred embodiment. The normal sequence is to proceed next to decision block  430  where a determination is made as to whether the job printout has been removed by monitoring the output bin sensor. If the determination is yes, then printing of the banner page is omitted or skipped over and the next print job if any may proceed. In the alternative if the determination is no then the counter is incremented at block  420 . This sequence loops until either the printout is picked up or the counter times out. If indeed the counter times out, then the banner page is printed as shown with block  440  and the next print job if there is one is queued up and printed.  
         [0025]    In order to facilitate the detection of banner pages, a particular pattern may be printed in a region easily accessible by the output bin sensor. In this manner it is possible to determine if the previous job has been removed while still leaving a stack of prior previously printed jobs in the output tray.  
         [0026]    In many cases it is still possible to reduce waste even after the initiation of banner page printing, by interrupting the printing process. In a laser printer the printing process includes the following steps: 1) charging a photoreceptor then 2) exposing the photoreceptor with a latent, followed by 3) development of that latent, and then 4) transferring of the developed image to paper, and finally 5) cleaning of the photoreceptor. It is simple to abort printing during or after step one and proceed directly to step 5) without printing the banner page. In principle it is possible, although not preferred to interrupt the process during or after stage 3) and at least save a piece of paper even if the supplies placed on the photoreceptor are thereby wasted.  
         [0027]    In a direct marking printer such as an ink jet printer there are no intermediate steps to interrupt. However, it is still possible to abort printing, thus saving on ink, even though this does not reduce the waste associated with the media (paper). There are also hybrid types of direct marking printers. In that situation the ink, typically a solid type ink, is printed onto a drum rather than directly on paper. This printing process can be interrupted during the time the image is being built up on the drum. A piece of paper can potentially be saved if a banner page abort comes prior to completion of the image. Ink from the intermediate image can be cleaned off by the normal cleaning system.  
         [0028]    In summary, practicing the methodology of the present invention reduces the amount of paper, toner, ink or other consumable wasted on banner sheets when human attendance is available to intervene. By providing a sensor at the output bin or making use of one already there, intelligence may be provided with a small amount of additional code in the controller. This allows a less frustrating experience for an end user who, if anxious for printout, is willing to remove the current printout and need not wait for a banner sheet. But perhaps more importantly it reduces the amount of waste created from discarded banner sheets.  
         [0029]    While the embodiment disclosed herein is preferred, it will be appreciated from this teaching that various alternative, modifications, variations or improvements therein may be made by those skilled in the art, which are intended to be encompassed by the following claims:
