Operation test/check

Function (Purpose) Used to check the operations of the sen-

sors and detectors in the paper reverse
section (duplex section) and its control cir-
cuit.

Duplex

Operation/Procedure
The operating conditions of the sensors and detectors are dis-
played.
The code names of the sensors and the detectors which are active
are highlighted.

Operation test/check

Function (Purpose) Used to check the operations of the load in

the switchback section (duplex section) and
its control circuit.

Duplex

Operation/Procedure
1)

Select the item to be operation checked with the touch panel
key.

2)

Press [EXECUTE] key.
The selected load performs the operation.
When [EXECUTE] key is pressed, the operation is terminated.

 

 

10-1

Operation test/check

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

supply mechanism (toner motor) and the
related circuit.

Process (Developing)

Operation/Procedure
1)

Select a target of the operation check.

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 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.

Cancel (Trouble etc.)

Function (Purpose) Used to cancel the self-diag "U1" trouble.
Section

Operation/Procedure
1)

Press [EXECUTE] key.

2)
