Control PCB
0008-8470
/ iR8070
1) Check to make sure that the Execute/Memory lamp in the control
panel is OFF, and turn off the main power switch.
2) Disconnect the power plug from the power outlet.
The machine remains supplied with power as long as its power plug is
connected to a power outlet even when its main power switch is turned
off. Be sure to disconnect the power plug.
3) Replace the potential sensor/potential control PCB.
The potential sensor and the potential control PCB are adjusted as a pair,
requiring simultaneous replacement.
4) Remove the developing assembly, and slide out the process unit.
5) Disconnect the connector [1] of the potential sensor.
F-14-90
6) Remove the two screws [1], and detach the potential sensor support
plate [2].
F-14-91
7) Put the developing assembly and the process unit back into their
initial positions.
8) Connect the connector [1] of the potential sensor.
