ABSTRACT:
A copying machine including an image forming section, a control unit, and memory means. The control unit has a memory storing data for controlling the image forming section. The memory means stores maintenance data which is generated every time said image forming means is operated and which represents maintenance items to be performed on the image forming section. When the machine is set in maintenance mode, the data is read from the memory. At the same time, at least one of the components of said image forming section, which needs to be replaced by a new one, is selected in accordance with the data stored in the memory means. The selected component is locked at a desired position, thereby to facilitate the replacing of the selected component and to reduce the time and cost required for maintenance work.
