4. Life end conditions
A. Toner cartridge
After detecting near end, when the toner density is lowered to the
specified level or lower and the toner sensor detects toner LOW
continuously for a certain time, it is judged as toner end.
B. Developer/Drum cartridge
• When the developer/drum counter exceeds the specified number
of sheets.
• When the rpm of the developer/drum cartridge exceeds the specified number.
In an actual use, in the correction operation and the warm-up operation as well as the output operation, the developer and the drum
rotate idly.
If the correction operation and the warm-up operation are made frequently, idle rotations of the developer and the drum are increased
accordingly.
Because of these factors, the consumption degree of the developer
and the drum cartridge cannot be determined only with the print
quantity. When, therefore, the number of rotations of the cartridge
exceeds the specified level, it is judged as life end.

Service Manual
1. General
Each adjustment item in the adjustment item list is associated with
a specific Job number. Perform the adjustment procedures in the
sequence of Job numbers from the smallest to the greatest.
However, there is no need to perform all the adjustment items. Perform only the necessary adjustments according to the need.
Unnecessary adjustments can be omitted. Even in this case, however, the sequence from the smallest to the greatest Job number
must be observed.
If the above precaution should be neglected, the adjustment would
not complete normally or trouble may occur.

ADJ 1 Adjusting high voltage values
1-A Adjust the main charger grid voltage
This adjustment is needed in the following situations:
* When the MC high voltage power PWB is replaced.
* U2 trouble has occurred.
* The PCU PWB has been replaced.
* The EEPROM of the PCU PWB has been replaced.
1) Enter the SIM 8-2 mode.
2) Select an output mode and an item to be adjusted.
3) Enter the adjustment value (specified value) in the middle
speed mode, and press [OK] key.
When [EXECUTE] key is pressed, the voltage entered in the
procedure 3 is outputted for 30sec and the set value is saved.
When [EXECUTE] key is pressed, the output is stopped.
Enter the adjustment value of each mode which is specified on the label attached on the MC high voltage power
PWB.
When the adjustment value (specified value) of the middle speed
mode is set, the adjustment values of the other modes are automatically set according to the middle speed mode setting in a certain relationship.
NOTE: Since the high voltage output cannot be checked with a
digital multi meter in this model, a judgment of the output
must be made by checking the print image quality.
1-B Adjust the developing bias voltage
This adjustment is needed in the following situations:
* When the MC high voltage power PWB is replaced.
* U2 trouble has occurred.
* The PCU PWB has been replaced.
* The EEPROM of the PCU PWB has been replaced.
1) Go through the modes specified in Simulation 8-1.
2) Select an output mode and an item to be adjusted.
3) Enter the adjustment value (specified value) in the middle
speed mode, and press [OK] key.

Enter the adjustment value of each mode which is specified on
the label attached on the MC high voltage power PWB.
NOTE: Note that the adjustment value may differ depending on the
MC high voltage power PWB.
Since the adjustment value label is attached on the MC
high voltage PWB, the PWB must be removed in order to
check the adjustment value.
This is a troublesome procedure. Therefore, it is advisable
to put down the adjustment value in advance.
