*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.

Purpose Adjustment/Operation test/check
Function Used to check and adjust the operation of the main
(Purpose) charger grid voltage (low mode) in each printer mode
and the control circuit.

Cleaning)
Photo conductor
Operation/procedure
After selecting the mode, enter the adjustment value and press the
[OK] key, and output will be made for 30sec.
The input value is in the increment of –25V.

The minimum increment is 2V.
The result of (Set value – 199) / 2 is stored in the EEPROM.
When reading a value from the EEPROM, the value of (EEP value *2)
+ 200 is used as the set value.
Therefore, the set value entered must be an even number. If an odd
number is entered the entered odd number + 1 is displayed after
pressing [OK] key.
