ABSTRACT:
In image forming apparatus pertaining to the present invention, after a malfunction is detected, the control of the image forming apparatus is carried out while isolating the malfunctioning device from said control, so that the image forming operation can be performed. It is determined whether a condition governing continued image forming exists during said isolating control. If said certain condition does not exist, the image forming operation is allowed to continue. Where said certain condition does exist, the image forming operation is suspended and subsequent image forming operations are prohibited, or a maintenance call request is displayed.
