*1. The negative value of the set value corresponds to the grid high
output voltage.
*2. The set values can be selected from the above 8 patterns only.
*3. The selected pattern determines the grid high voltage and the grid
low voltage.
If, for example, the grid high voltage is set to –480V (pattern 1), the
grid low voltage is –350V.
Operation/procedure
Enter the adjustment value and press the [OK] key, and output opera-
tion is performed for 30sec.

Operation/procedure
Select with the 10-key and operate for 30 seconds.
Operation/procedure
Set the rotation speed of the duplex motor.
Operation/procedure
Set the switch back time of the duplex motor.
Operation/procedure
Press the [OK] key and operate the toner motor for 30 sec.
Pressing the [INTERRUPT] key interrupts the operation, and the dis-
play returns to the main code entry screen.
