MX-M565N  ADJUSTMENTS AND SETTINGS  4 – 5

3)

After completion of the adjustment of the toner density control
reference value, insert the toner cartridge.

4)

Close the front cabinet.

5)

When [EXECUTE] key is pressed, it is highlighted. The devel-
oping roller rotates, and the toner density sensor detects toner
density, and the output value is displayed. The above opera-
tion is executed for 2 minutes, and the average value of the
toner density sensor detection level is set (saved) as the refer-
ence toner density control value. When the reference toner
density control adjustment operation is completed, [EXE-
CUTE] key returns to normal from highlight. This makes known
about whether the adjustment operation is completed or not.

NOTE:
If the operation is interrupted within 2 minutes, the adjustment
result is not reflected. When [EXECUTE] key is pressed during
rotation, the operation is stopped and [EXECUTE] key returns
to the normal display. If [EE-EU], [EE-EL] or [EE-EC] is dis-
played, setting of the reference toner density control value is
not completed normally.

NOTE: When not replacing the developer, do not execute SIM25-

2.

 

 

This adjustment is needed in the following situations:

* When the high voltage 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.

Enter the adjustment value of each mode which is specified on
the label attached on the high voltage power PWB.

GBK: XXX

The default value s specified for each model must be changed
as follows. 46cpm/56cpm machine: +5

Note that the adjustment value may differ depending on the high
voltage power PWB. Since the adjustment value label is attached
on the 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. When the adjustment value (specified value) of the mid-
dle 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.

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.
