Fault

Description

The printed image is light, with no ghost.

Light image (3)

Model ML-xxxx

Check

1. Engine board

2. Main body

Cause

1. Engine board bias (350-485V) and supply voltage (570-630V) may be low (Perform DCU diagnostic

mode 04 to measure the voltage).

2. Direct strong light may be entered into the manual feed slot.

Solution

1. Check the following parts :

U201(KA324), Q204(D526-Y), T204(Transformer), U203(SN7407N), resistors, diodes in the output
and feedback area.

2. Check if contrast mode is set to ‘Light’. If not, change the install position of the printer or attach

OPC cover sheet (P/No: JC72-49093A).

Remark

Bias and supply voltage check point:
U203; #9 pulse input, #8 pulse output
