Abstract
An image forming apparatus which is capable of feeding paper from a paper feeding unit when paper types set in selected paper feeding units are all the same type even if the selected paper feeding units do not include a paper feeding unit in which a predetermined paper type is set. At least one of paper feeding portions stacking a paper with the designated paper size is selected based on an attribute set to each of a plurality of paper feeding portions. in a case where a selected plurality of paper feeding portions do not include a paper feeding portion set with the predetermined attribute when the attributes set to the selected plurality of paper feeding portions are the same, a paper is fed to the image forming unit from any one of the selected plurality of paper feeding portions.
Claims16
An image forming apparatus comprising:
- an input unit adapted to input image data;
- an image forming unit adapted to form an image on a paper based on the image data inputted by said input unit;
- a paper feeding unit adapted to feed a paper to said image forming unit, said paper feeding unit including a plurality of paper feeding portions;
- a setting unit adapted to set an attribute of a paper stacked on each of the plurality of paper feeding portions;
- a designating unit adapted to designate a paper size for said image forming unit to form an image from image data inputted by said input unit;
- a selecting unit adapted to select at least one of paper feeding portions stacking a paper with the paper size designated by said designating unit based on the setting by said setting unit;
- and
- a controlling unit adapted to control to feed a paper to said image forming unit from a paper feeding portion set with a predetermined attribute when the paper feeding portions selected by said selecting unit include the paper feeding portion set with the predetermined attribute related to the paper,
- wherein said controlling unit controls, in a case where a plurality of paper feeding portions selected by said selecting unit do not include a paper feeding portion set with the predetermined attribute when the attributes set to the selected plurality of paper feeding portions are the same, to feed a paper to said image forming unit from any one of the selected plurality of paper feeding portions.
A control method of an image forming apparatus, comprising:
- an input step of inputting image data;
- an image forming step of forming an image on a paper based on image data inputted in said input step using an image forming unit;
- a paper feeding step of feeding a paper on which an image is to be formed in said image forming step from any one of a plurality of paper feeding portions;
- a setting step of setting an attribute of a paper stacked on each of the plurality of paper feeding portions;
- a designating step of designating a paper size to form an image in said image forming step from image data inputted in said input step;
- a selecting step of selecting at least one of paper feeding portions stacking a paper with the paper size designated in said designating step based on the setting in said setting step;
- and
- a controlling step of controlling to feed a paper to said image forming unit from a paper feeding portion set with a predetermined attribute when the paper feeding portions selected in said selecting step include a paper feeding portion set with the predetermined attribute related to the paper,
- wherein said controlling step controls, in the case where a plurality of paper feeding portions selected in said selecting step do not include a paper feeding portion set with the predetermined attribute when the attributes set to the selected plurality of paper feeding portions are the same, to feed a paper to said image forming unit from any one of the selected plurality of paper feeding portions.
