related circuit.
Section
Process (Developing)
Operation/Procedure
1)
Select a target of the operation check with the touch panel key.
2)
Press [EXECUTE] key.
The selected load operation is performed for 10 sec.
When [EXECUTE] key is pressed, the operation is terminated.
CAUTION: This simulation must be executed without installing the
toner cartridges.
If this simulation is executed with the toner cartridges
installed, toner will be forcibly supplied to the develop-
ing unit, resulting in overtoner.
If this simulation is erroneously executed with the toner
cartridges installed, overtoner state may be deleted by
making a few black background copy in the copy mode.
