Abstract
A checking apparatus for a copier includes check drive circuits having functions indentical to that of load driving circuits normally operated by a controller. The load driving circuits are bypassed in the check mode so that the loads are selectively operated by the check drive circuits, to test the output of a microprocessor or like device serving as a controller.
