7.10.18 Charging Wire
7.10.18.1 Outline
0009-5713
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.
7.10.18.2 Routing the Charging Wire
0009-5715
All charging wires (except the grid wire) are routed more or less in the
same way; the following 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.
F-7-215
For other charging assemblies, remove the two lids.
3) Free a length of about 5 cm of charging wire from the charging wire
reel (0.06 mm in diameter), and form a loop at its end with a diameter
of about 2 mm.
MEMO:
To form a loop, wind the charging wire around a hex key once, and turn
the hex key three to four times; then, twist the charg-ing wire.
4) Cut the end (excess) of the twisted charging wire.
5) Hook the loop on the stud.

6) At the rear, hook the charging wire on the charging wire positioner;
then, hook the charging wire tension spring on the charging wire
where indicated to the following figure.
F-7-217
7) Cut off the excess of the charging wire with nippers.
8) Pick the end of the charging wire tension spring with tweezers, and
hook it on the charging power supply electrode.
In the case of the pre-transfer charging assembly, hook the spring on the
pin at the front.
