tion is terminated.

 

 

10-1

Operation test/check

Function (Purpose) Used to check the operations of the toner

supply mechanism (toner clutch) and the
related circuit.

Toner supply, developing

Operation/Procedure
1)

Press [EXECUTE] key.
The selected load operation is performed for 10 sec.
When [EXECUTE] key is pressed during operation, the opera-
tion 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 over toner.
If this simulation is erroneously executed with the toner car-
tridge installed, the over toner state may be canceled by
making several background copies.
