7.8 Charging Wire
7.8.1 Outline
The photosensitive drum is surrounded by three charging wires (for primary charging,
pre-transfer, and transfer/separation).
These charging wires are newly adopted brown wires (0.06 mm in diameter). Do not use a
gold-plated wire, which has been used in the past; otherwise, image faults may occur.
Further, be sure to use a strengthened polishing pad (in a blue holder) as the cleaning pad
for the primary charging assembly and the transfer charging assembly.
7.8.2 Removing the Wire Cleaner of the Primary Charging Assembly
1) Pick the wire cleaner, and disengage the
hook with a flat-blade screwdriver.

7.8.3 Routing the Charging Wire
All charging wires (except the grid wire) are routed more or less in the same way; the fol-
lowing cites the primary charging assembly:
1) Remove the shielding plate (left, right)
of the charging assembly. To prevent
deformation (slack) in the primary
charging assembly, be sure to work
separately for the left shielding plate
and the right shielding plate (i.e., do not
loosen the mounting screws [1] of both
shielding plates at the same time).
2) Remove the wire cleaner.
F04-708-02
For other charging assemblies,
remove the two lids.
