PROBABLE CAUSES:

1. Failing exposure lamp. If the lamp has become discolored, change the lamp.

2. Failure of Image Processing Board or CCD Board. If "NG" is displayed when "Scanning check" of "Function (IR)" is run, check the optical path or change

the Image Processing Board or the CCD Board.

3. Problem with operation of power supply board. Check to see if the voltage across PJ9C-4 on Power Supply board and GND is DC24V after the malfunction

has been reset. If so, check or change the flat cable, the Inverter Board, or the Image Processing Board.

For additional details, please see the Field Service Manual (approx. 4 MB).

Description

There is low density image after an F8 Operation.

Solution

CAUSE: The PH Control lasts approx. 60 sec. after turning on the main switch (or open/close the front door.) If the F8 operation is implemented during the

PH Control operation, the LD stays light out. Because the PC drum attracts toner due to the LD light, the T/C target level of the starter is reduced by 1%

against its correct value. As a consequence of that, the ATDC adjustment does not work properly, and may lead to "Low density image" or "carrier adhesion at

high light density area".

SOLUTION: Wait for the print head control to finish before running an F8 operation.
