mm, or black spots occur else-
where, the OPC drum surface is
damaged.
2. If dark or blurry black spots occur
periodically, the rollers in the Devel-
oper may be contaminated with for-
eign matter or paper particles.
(Charge roller: 37.7 mm interval,
OPC drum: 75.5 mm interval)
3. If a black image is partially bro-
ken, the transfer voltage is abnor-
mal or the transfer roller's life has
expired.
