The following signals are associated with the mechanism:
[1] Primary charging leakage detection signal; when '0', if the current is too high or too low
[2] Primary corona current control signal; used to control the primary charging current generated by the high-voltage PCB
[3] High-voltage remote signal; turning on/off the primary charging corona current output
7.5.2.2 Primary Charging Assembly Cleaning Mechanism
0015-4489
iR5065 / iR 5055 / iR5075 / / /
The primary charging wire cleaning mechanism is turned on at the following timing, and the construction of the control system is as shown:
Timing of Cleaning
- when the wire cleaning mechanism is executed in user mode
- when the wire cleaning mechanism is executed in service mode:
COPIER>FUNCTION>CLEANING>WIRE-CLN*1
- after the end of cleaning, at the end of every 2,000 prints*2
- in a low temperature or high humidity environment, if the fixing roller is 160 deg C or less when the power is turned on
*1: The machine executes it when the primary charging wire or the transfer charging wire has been replaced.
*2: The default cleaning interval may be changed in service mode (COPIER> OPTION> BODY> W-CLN-P).

The following signals are associated with the mechanism:
[1] Primary charging wire cleaning motor reverse direction signal; when '1', the wire cleaner moves toward the rear.
[2] Primary changing wire cleaning motor normal direction signal; when '1', the wire cleaner moves toward the front.
