ABSTRACT:
An image forming device is disclosed which includes a problem detection unit for detecting problem, and problem alert unit for alerting a user to the detection of a problem. Until an initially detected problem A has been resolved, the problem alert unit will not issue a problem alert based upon a subsequently detected problem B. Consequently, when working to resolve a problem, if a subsequent problem B is detected, the detection of the problem B will be disregarded, and a problem alert will not be issued (by a buzzer or the like), and thus the user can devote themselves to resolving problem A without being disturbed by the buzzer or the like.
