Abstract

The present disclosure provides an image forming apparatus capable of easily performing jam processing. When an occurrence of a jam of a sheet which is conveyed on a conveying path is detected, the image forming apparatus displays a jam processing display screen which guides processing in accordance with a position where the jam has occurred. After the processing in accordance with the jam processing display screen is performed, if a state of the jam remains unchanged, the image forming apparatus performs forced feeding which forcibly conveys the sheet to a predetermined position. The image forming apparatus displays the jam processing display screen urging to perform processing in accordance with the position of the sheet after the sheet is forcibly conveyed.

Dependent claims

An image forming apparatus comprising:

a conveyer configured to convey a sheet on a conveying path;
a jam detector configured to detect a jam of a sheet which is conveyed by the conveyer;
a display configured to display information;
and
a controller configured to perform control for jam processing if a jam is detected by the jam detector,
wherein the controller performs following functions:
a first display function to display first jam processing information on the display, the first jam processing information representing a processing procedure for releasing a jam in accordance with a position where the jam occurs;
a forcibly feeding function to forcibly convey the sheet to a predetermined position by the conveyer if, after processing for releasing a jam in accordance with the first jam processing information is performed, a state of the jam remains unchanged;
and
a second display function to display second jam processing information on the display, the second jam processing information representing a processing procedure for releasing a jam in accordance with the predetermined position after a sheet is conveyed by the forcibly feeding function.

7 more elements

A jam processing method performed by an image forming apparatus comprising a plurality of detectors for detecting a sheet which is conveyed along a conveying path, the method comprising:

detecting an occurrence of a jam of the sheet at detection timing of the sheet at a first detector and a second detector and informing first jam processing information representing a processing procedure for releasing a jam in accordance with a position where the jam occurs;
and
after processing in accordance with the first jam processing information is performed, if a state of the jam remains unchanged, forcibly conveying the sheet to a predetermined position, and informing second jam processing information representing a processing procedure for releasing a jam in accordance with the predetermined position after the sheet is forcibly conveyed.
