[Problems to be solved by the invention]
However, the conventional self-diagnosis function has the following problems.
That is, the malfunction of the copying machine is not limited to such a malfunction as a component failure, and an unexpected malfunction may occur. That is, there is a case where a failure is rarely detected due to a noise relationship, although the failure is not a failure such as a component failure (see Patent Document 2).
Such a defect does not require any particular repair, and is restored only by simply turning off / on the power supply. Thereafter, the device operates normally, so that only a user action is sufficient. In other words, it can be said that a defect caused by a soft bug or noise can be restored by turning off / on the power supply without performing any repair.
On the other hand, an abnormality due to a hardware failure causes the same abnormal state to occur many times unless the defective part is repaired, and is detected by self-diagnosis.
However, in the related art, an abnormality due to a hardware failure and an abnormality due to noise or the like are handled in the same manner without distinction. For this reason, even in the case of a software bug or a malfunction caused by noise, etc. that requires only turning off / on the power, a message such as "Please contact service" is displayed, and it is not possible to notify the user of an appropriate action. I was
The present invention provides a copying machine and a composite having a copying function capable of notifying a user of an accurate treatment method by separating the content of abnormality information to a user between an abnormality due to a hardware defect and an accidental abnormality due to noise or the like. The purpose is to provide a machine.
