Fault

Description

The printed image is light, with no ghost.

Light image (2)

Model ML-6100

Check

Engine board

Cause

1. Charge voltage (=MHV) on the engine board exceeds 1520V. (Perform DCU diagnostic mode 01 to

measure the voltage).

2. No power to the supply roller.

Solution

Check the following parts and replace if defective :
U201(KA324), Q211(C1008), T202(Transformer),
resistors, and diodes in the output and feedback area.

Remark

Check the charge voltage (MHV) at :
U201; while operating, #10/#9 2.5~2.9V, #8 5.5~8.5V

while idling, #9 2.7V, #10/#8 0V

Q201 operating voltage; Base 2~2.5V, Emitter 0~1V, Collector 30~60V
U203; #1 0V input, #2 0V output
