Sharp MXM363N

This adjustment is needed in the following situations:

• When developer is replaced.

NOTE:
Be sure to execute this adjustment only when developer is replaced. Never execute it in the other cases.

1. With the front cabinet open, enter SIM 25-2. When setting the toner density control reference value, pull out the toner cartridge in advance.
2. Close the front cabinet and press [EXECUTE] button.
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 developing roller rotates, and the toner density sensor detects toner density, and the output value is displayed.
   The above operation is executed for 3 minutes, and the average value of the toner density sensor detection level is set (saved) as the reference toner density control value.
   When the reference toner density control adjustment operation is completed, [EXECUTE] 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 3 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 displayed, setting of the reference toner density control value is not completed normally.
