Abstract
A sheet transportation control method and an image forming apparatus are provided with which it is possible to prevent, by changing a set time, frequent detection of abnormal transportation. In an image forming apparatusin which a paper jam (abnormal transportation) is detected based on the timing of detection of a sheet on which an image will be formed by each one of sheet sensors disposed along a transportation path along which said sheet is transported and based on a jam detection time (set time) stored in advance within a flash memory (storage part)and paper transportation and image formation is stopped upon detection of a paper jam, when it is determined to change the jam detection time, a post-change jam detection time is determined and the jam detection time stored in the flash memoryis changed to thus determined jam detection time.
