(7) A black line ap-
pear laterally.
Causes
1. Flawed drum.
2. Poor developing bias wire contact.
3. Dirty developing section.
4. No developing bias output.
Flawed drum.
Poor developing bias wire con-
tact.
Dirty developing section.
No developing bias output.
The developing bias wire is
shorted or makes poor con-
tact.
Defective MPCB.
Defective HVTPCB.
Check the drum visually. If it is flawed, replace
(see page 3-3-72).
Check for poor developing bias wire contact.
Check for part contaminated with toner or carrier
in the developing section.
Check the developing bias wire and, if there is a
problem, replace.
Run simulation 10. If CN 1-7 on the MPCB fails to
go low, replace the MPCB.
Run simulation 10. If the developing bias is not
output while the MPCB is okay, replace the
HVTPCB.
