Abstract
When a menu of “SHEET SIZE SETTING” is chosen, a main CPU scans a non-fixed-sized sheet once, and takes in a scanned image. Based on the taken-in image, the main CPU detects the size of the sheet and sets the sheet size of a selected sheet cassette. The main CPU controls image formation using the non-fixed-sized sheet set in the sheet cassette.
Claims8
An image forming apparatus having a plurality of cassettes for containing paper sheets, and forming an image on a paper sheet fed from one of the cassettes, the apparatus comprising:
- a designating section which designates the cassette in which a paper sheet for image formation by the image forming apparatus is to be set;
- an image read section which reads an image of the paper sheet to be set in the cassette designated by the designating section, when said paper sheet is placed on an original table;
- and
- a control section which executes a control to detect the size of the paper sheet on the basis of the image read by the image read section and causes a display section provided on an operation panel of the image forming apparatus to display the detected size of the paper sheet,
- wherein the control section causes a display section provided on the cassette designated by the designating section to display the detected size of the paper sheet.
An image forming apparatus having a plurality of cassettes for containing paper sheets, and forming an image on a tab sheet fed from one of the cassettes, the apparatus comprising:
- a designating section which designates the cassette in which a tab sheet for image formation by the image forming apparatus is to be set;
- an image read section which reads an image of the tab sheet to be set in the cassette designated by the designating section, when said tab sheet is placed on an original table;
- and
- a control section which causes the display section provided on the operation panel of the image forming apparatus to display the shape of the tab sheet, and detects the size of a tab section of the tab sheet.
An image forming apparatus having a plurality of cassettes for containing paper sheets, and forming an image on a paper sheet fed from one of the cassettes, the apparatus comprising:
- a designating section which designates the cassette in which a paper sheet for image formation by the image forming apparatus is to be set;
- an image read section which reads an image of the paper sheet to be set in the cassette designated by the designating section, when said paper sheet is placed on an original table;
- and
- a control section which executes a control to detect the size of the paper sheet on the basis of the image read by the image read section and causes a display section provided on an operation panel of the image forming apparatus to display the detected size of the paper sheet,
- wherein the control section causes the display section to display the cassette in which the paper sheet for image formation by the image forming apparatus is to be set and a sheet size detected at a display cassette which corresponds to the cassette designated by the designating section.
