Abstract
In addition to a parameter commonly used for all printing jobs, a parameter used for each printing job is also set at the performing of the print job. During the performing of the print job, when no available sheet is left, a switching is effected to another sheet supplying tray on the basis of the commonly used parameter and parameter for each printing job. By doing so it is possible to, during the performing of the print job, prevent a switching to a sheet supply tray in which a sheet not wanted by the user is held.
Claims9
An image forming method applied to an image forming apparatus which has a plurality of supplying trays holding an image forming medium and which performs image formation for each of a plurality of print jobs, said image forming method comprising the steps of:
- causing a managing section to manage said plurality of print jobs;
- causing a first memory to store first attribute information indicating an attribute of each supplying tray used in common in all said print jobs managed by the managing section, and causing a second memory to store second attribute information indicating an attribute relating to each supplying tray for each print job, when each print job is to be executed;
- and,
- when the image forming processing corresponding to the print jobs managed by the managing section is performed, selecting a given supplying tray holding the image forming medium on the basis of the first attribute information and the second attribute information corresponding to the print job to be executed.

- when the image forming processing corresponding to the print jobs managed by the managing section is performed, selecting a given supplying tray holding an image forming medium on the basis of the first attribute information and the second attribute information corresponding to the print job to be executed;
- and,
- when, during execution of the print jobs, no available image forming medium is left in the selected supplying tray, effecting a switching to any other supplying tray on the basis of the first attribute information and the second attribute information corresponding to the print job to be executed, said other supplying tray holding the same image forming medium as that in the selected supplying tray.
An image forming apparatus which has a plurality of supplying trays holding an image forming medium and which performs image formation for each of a plurality of print jobs, said image forming apparatus comprising:
- a managing section that manages said plurality of print jobs;
- a first memory for storing first attribute information indicating an attribute of each supplying tray used in common in all said print jobs managed by the managing section;
- a second memory for storing second attribute information indicating an attribute relating to each supplying tray for each print job, when each print is to be executed;
- and,
- a controller for selecting a supplying tray holding an image forming medium on the basis of the first attribute information and the second attribute information corresponding to the print job to be executed.
