If the temperature of the fixing assembly is 150 deg C or higher when the
main power switch is tuerned on, the machine will not execute potential con-
trol. If such is the case after replacing the scanner unit, manually execute po-
tential control in service mode as follows:
1) Make the following selections in service mode: COPIER> FUNCTION>
DPC> DPC; then, enter '1', and press [OK].
2) Turn off and then back on the main power switch.
14.5 Image Formation System
14.5.1 Outline
0015-9961
iR5065 / iR 5055 / iR5075 / / /
The photosensitive drum is surrounded by 3 charging wires; the primary
charging wire, the pre-transfer charging wire, and the transfer/separation
charging wire.
These charging wires are newly adopted brown wires (0.06 mm in diameter).
Do not use a gold-plated wire that has been used in the past; otherwise, image
fault 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 as-
sembly.
14.5.2 Routing Charging Wire
0015-9962
iR5065 / iR 5055 / iR5075 / / /
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 shield plates (left, right) of the charging assembly. To prevent
deformation (deflection) in the primary charging assembly, be sure to
work separately for the left shielding plate and the right shielding plate
(do not loosen the screws [1] of both shielding plates at the same time.)
2) Remove the wire cleaner.
