4-2-3 Horizontal Black Band
• Description
1. Dark or blurry horizontal stripes occur in the printing periodically.
(They may not occur periodically.)

Check and Cause
Solution
1. Bad contacts of the voltage terminals to
developer.
2. The rollers of developer may be stained.
Charge roller = 37 mm
Supply roller = 27 mm
Develop roller = 32 mm
Transfer roller = 47 mm
1. Clean each voltage terminal of the Charge,
Supply, Develop and Transfer roller.
(remove the toner particles and paper par-
ticles)
2. Clean the right Gear that has relatively
small gap of the teeth in the OPC.
3. If the malfunction persists, replace the
developer.
4-2-4 Black/White Spot
• Description
1. Dark or blurry black spots occur periodically in the printing.
2. White spots occur periodically in the printing.

Check and Cause
Solution
1. If dark or blurry black spots occur periodi-
cally, the rollers in the Developer may be
contaminated with foreign matte or paper
particles.
( Charge roller : 37 mm interval
OPC drum : 75mm interval)
2. If faded areas or voids occur in a black
image at intervals of 75 mm, or black
spots occur elsewhere, the OPC drum
surface is damaged.
3. If a black image is partially broken, the
transfer voltage is abnormal or the trans-
fer roller's life has expired.
1. Run OPC cleaning Mode Print and run the
Self-test 2 or 3 times.
2. In case of 75mm interval unremovable in 1,
cleanly remove foreign substances stuck on
the OPC location equivalent to black spots
and white spots with a dry duster.
3.
The transfer roller guarantees 50,000
sheets printing. If the roller's life is expired,
replace it.
4. In case of 37mm interval unremovable in 1,
take measures as to replace the developer
cartridge and try to print out.
5. Clean the inside of the set against the paper
particles and foreign matter in order not to
cause the trouble.
