No image
1. GND OPC is well grounded?
2. LSU running well?
3. Biss voltage is normal?
4. Lower toner?
5. Is there video data from Main PBA
1. Measure the resistance between frame
ground and the ground spring attached frame.
Confirm stable ground. Unless bad ground,
detach cabinet, check where is bad point
2.Adjust LSU or replace it
3. Normal Dev bias = -450V
4. Shake toner cartridge and print.If a like
good, toner is empty
5. Test engine test pattern , replace Main PBA
Light image
1. LSU light power normal?
2. Enough toner?
3. High charger voltage?
4. Lower bias voltage
5. Contamination of high voltage contact.
6. Transfer volatge and roller.
1. LSU light power check is difficult.
Compare with new one and check.
2. Check toner and the toner cartridge counter
3~4. Measure all high voltage output.
5. Leakage toner cause bad contact and
increase contact resistance. Clean contami-
nated area.
