ABSTRACT:
An image forming apparatus has a rotatable member, a plurality of processing devices for forming an image on the rotatable member and transferring the image to transfer material, a device for fixing the transferred image, circuitry for controlling the operation of the rotating member and processing devices so that when the power switch is turned on at least the fixing device is turned on and when the power switch is turned off the fixing device is turned off while the rotation of the rotatable member is continued. The apparatus also includes a signal generating device associated with one of the processing devices, a first detector for detecting transfer material and a second detector for detecting the position of an original carriage, and circuitry for checking for a paper jam by counting signals from the time of the second detector signal. The apparatus also includes a detector for detecting the home position of the original carriage, setting structure for setting the carriage to the home position and resetting structure for preventing the start of processing immediately upon operation of a manual start switch.
