CHAPTER 4 IMAGE FORMATION SYSTEM

7.8 Charging Wire

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.

1) Pick the wire cleaner, and disengage the

hook with a flat-blade screwdriver.

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.

For other charging assemblies,

remove the two lids.
