1.2 Self-Diagnosis Modes
Since this copier is designed to cope with multifunctions such as those of a network printer and DSS, there
are many setting items which are related to each other in the self-diagnosis modes.
Malfunctions such as machine locking can be caused by the internal structural problem of the program
when a normal operation is attempted by pressing [0] and [9] simultaneously or [C/S] on the control panel
subsequently to the adjustment.
Therefore, turn OFF the power after using the self-diagnosis mode for adjustment after unpacking, service
or preventive maintenance, and then leave the machine to the customer.
