Operation/
Procedure

The transfer charger output voltage in printing the front and the back of paper can be adjusted and checked.

1. Select the print mode with [

↑

] key and [

↓

] key.

2. Enter the adjustment value with the 10-key pad.

3. Press the [EXECUTE] key.

The [EXECUTE] key is highlighted, the adjustment value entered in procedure 2 is set, and the voltage corresponding
to the set value is supplied.

After supplying the voltage for 30 sec, the [EXECUTE] key returns to the normal display.

If the [EXECUTE] key is pressed while the voltage is supplied, the voltage output is stopped and the [EXECUTE] key
returns to the normal display.

Purpose

Operation test/check

Function
(Purpose)

Used to check the operation of the toner motor and its control circuit.
(Note)
Do not execute this simulation with toner in the toner hopper. If executed, excessive toner may enter the
developing section, causing an overtoner trouble. Be sure to remove the toner motor from the toner hopper before
executing this simulation.
