Print-Quality Troubleshooting
Black/White Spot
Dark or blurry black spots occur periodically in the printing.
White spots occur periodically in the printing.
Light Image
The printed image is light, with no ghost.
Check and Cause Solution
If dark or blurry black spots occur
periodically, the rollers in the Print
Cartridge may be contaminated with
foreign matter or paper particles.
(Charge roller: 37.7 mm interval
OPC drum: 75.5 mm interval)
Run OPC cleaning Mode Print and run
the Self-test 2 or 3 times.
If faded areas or voids occur in
a black image at intervals of 75.5 mm,
or black spots occur elsewhere, the OPC
drum surface is damaged.
In case of 75.5 mm interval
unremovable in 1, cleanly remove
foreign substances stuck on the OPC
location equivalent to black spots and
white spots with a dry duster.
If a black image is partially broken, the
transfer voltage is abnormal or the
transfer roller's life has expired.
The transfer roller guarantees 70.000
sheets printing. If the roller's life is
expired, replace it.
In case of 37.7 mm interval
unremovable in 1, take measures as to
replace the print cartridge and try to
print out.
Clean the inside of the set against the
paper particles and foreign matter in
order not to cause the trouble.
Check and Cause Solution
Check if the Toner Save Mode is off. Set Toner Save Mode to OFF.

print cartridge is near end of life.
Replace the print cartridge and try to
