Abstract

A device for controlling a process of stopping a laser printer having a printing unit including a sensitive drum and a fixing unit. The stopping process control device is provided with a detecting unit for detecting errors occurring in the laser printer, a determining unit for determining whether or not an error detected by the detecting unit is very serious, and a control unit for controlling the printing unit and the fixing unit. The control unit stops the printing unit and the fixing unit after completing a printing and a fixing of the page being printed when the determining unit determines that the error is less serious, and conversely, immediately stops the printing unit and the fixing unit when the determining unit determines that the error is very serious.
