Section
Operation/Procedure
1) Select a target of the operation check with the touch panel key.
When [ALL ] key is pressed, all the items are selected.
2) Press [EXECUTE] key.
The selected load operation is performed for 10 sec.
When [EXECUTE] key is pressed, the operation is terminated.
NOTE: 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 developing
unit, resulting in overtoner.
If this simulation is erroneously executed with the toner car-
tridges installed, overtoner state may be deleted by making
a few black background copy in the single color copy mode
of the target color.
