Description

  The present invention relates to a technique for feeding a sheet in an image forming apparatus that forms an image on a sheet.

  An image forming apparatus such as a printer generally includes a plurality of sheet feeding trays, and selects one of the plurality of sheet feeding trays to form an image on a sheet stored in the selected sheet feeding tray. It is. In such an image forming apparatus, the paper feed tray is selected by sending data representing an output image described in a page description language (hereinafter referred to as “output request data”) from another device such as a personal computer via a communication network. This is performed by determining information (hereinafter, “tray designation information”) for selecting a paper feed tray included in the received output request data.

  By the way, the tray designation information included in the output request data may designate a paper feed tray that does not actually exist in the image forming apparatus. This can occur, for example, when a user purchases a new printer and uses a different printer, when the user's system (environment) is changed, or when the specification of the image forming apparatus is changed. As described above, when a paper feed tray that does not physically exist is selected, there is a problem that the image forming process does not operate normally.

Even when a tray that does not physically exist is selected, as a method for normally performing image forming processing, for example, Patent Document 1 discloses a case where a paper discharge tray that does not physically exist is designated. Has proposed a method of associating with a paper discharge tray that actually exists.
Patent Document 2 proposes a method for setting an emulation that can be used for each paper feed tray. According to this method, it is possible to reliably select a paper feed unit suitable for emulation and use it. User convenience can be improved.

<B: Operation>
A specific operation executed by the image forming apparatus 1 based on the above configuration will be described below.
First, a user of the image forming apparatus 1 operates an apparatus such as the personal computer apparatus 3 to transmit output request data indicating an image output request to the image forming apparatus 1 via the communication network 4. When detecting that the output request data has been received, the control unit 40 of the image forming apparatus 1 records a record of a combination of “owner ID”, “PDL version”, and “service ID” included in the received output request data. A search is performed from the user setting table TBL1, and the “user ID” of the searched record is read from the storage unit 60.

  Subsequently, the control unit 40 of the image forming apparatus 1 retrieves the read user ID from the tray setting management table TBL2 stored in the storage unit 60, and selects the tray setting table corresponding to the user ID. Then, the control unit 40 searches the selected tray setting table for tray designation information included in the received output request data, and reads the tray ID corresponding to the tray designation information. The paper feed tray 21 is selected by the above processing.

  The control unit 40 of the image forming apparatus 1 causes the image forming unit 10 to perform image formation based on the received output request data and the read “tray ID”. That is, the control unit 40 converts the data representing the image included in the output request data to generate YMCK data, supplies the generated YMCK data to the image forming unit 10, and controls the sheet supply unit 20, The sheets are conveyed one by one from the sheet feeding tray 21 indicated by the identified tray ID and conveyed to the image forming unit 10. The image forming unit 10 forms Y, M, C, and K toner images on the sheet conveyed from the sheet supply unit 20 based on the supplied YMCK data, and forms an image on the sheet.

  For example, in the case of the computer apparatus 3 in which a driver that generates output request data corresponding to the image forming apparatus 2 is installed, the tray designation information included in the output request data transmitted from the computer apparatus 3 is the image forming apparatus 1. May not correspond to the paper feed tray 21 that actually exists. Even in such a case, in the present embodiment, since the tray setting table corresponding to the type of PDL is selected, it is possible to select the paper feed tray 21 included in the image forming apparatus 1.

As described above, in this embodiment, a user ID is assigned for each user, service, and PDL version, and the tray setting table used for selecting a tray is switched according to the assigned user ID. Even when the included tray designation information designates a paper feed tray that does not actually exist, it is possible to select a paper feed tray that actually exists. Furthermore, it is possible to use different paper feed trays for each user and service.
In this way, it is possible to perform paper feed control on the image forming apparatus side without changing the system used by the user. Further, since the table can be set by the user, customization according to the user's system becomes possible.
