1. Change Toner cartridge
2. Replace LSU
1. Clean LSU window
2. If not LSU, change Toner cartridge
1. Removing seal tipe
2. 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
3.Adjust LSU or replace it
4. Normal Dev bias = -300V
5. Shake toner cartridge and print.If a liitke
good, toner is empty
6. Test engine test pattern with DCU,
replace Video board
1. Check and remove tape
2. LSU light power check is difficult.
Compare with new one and check.
3. Check toner and developer counter
4~5. Measure all high voltage output
6. Leakage toner cause bad contact and
increase contact resistance. Clean
contaminated area.
1. Check the rated level and replace
2. Set to power rating
3. Replace defected board
1. Adjust to the rated status
2. Replace Toner cartridge
1. Check every high voltage
2. Check the turn-on PTL, LED crash
3. Clean the inside machine or replace
toner cartridge
1. Bad blade of Toner cartridge
2. LSU
1. LSU window contamination
2. Toner cartridge
1. Seal tape is removed?
2. GND OPC is well grounded?
3. LSU running well?
4. Biss voltage is normal?
5. Lower toner?
6. Is there video data from controller?
1. Check seal tape removing
2. LSU light power normal?
3. Enough toner?
4. High charger voltage?
5. Lower bias voltage
6. Contamination of high voltage
contact
7. Transfer volatge and roller
1. LSU light power normal?
2. Bias voltage output is high?
3. Video data is always supplied?
1. High voltage output is normal?
2. C/R of Toner cartridge is
contaminated?
1. High voltage output
2. Pre-Transfer Lamp
3. Bad high voltage contact
