Others; Transfer Charging Assembly Cleaning Mechanism - Canon imageRUNNER 5065 series Service Manual

Chapter 7
SERVICE MODE:
COPIER>OPTION>BODY>FUZZY (turning on/off fuzzy control)
0: turns off fuzzy control (default)
1: low humidity mode (for lower transfer charging current than standard)
2: normal humidity mode
3: high humidity mode (for higher transfer charging current than normal)
When set to '1' through '3', the machine executes the appropriate modes independently of the reading of the environment sensor.

7.8.1.3 Transfer Charging Assembly Cleaning Mechanism

iR5065 / iR 5055 / iR5075 / / /
The following shows the timing at which transfer charging wire cleaning is executed and the construction of the associated system:
Timing
1. when wire cleaning is executed in user mode
2. when wire cleaning is executed in service mode (COPIER> FUNCTION> CLEANING> WIRE-CLN)*1
3. at the end of every 2,000 prints after the end of cleaning*2
4. if the fixing roller is 160 deg C or less in a low temperature or high humidity environment
*1: The machine executes wire cleaning when the primary charging wire or the transfer charging wire has been replaced.
*2: The default cleaning interval may be adjusted in service mode: COPIER> OPTION> BODY> W-CLN-P.
The following signals are used in association with the cleaning mechanism:
[1] Transfer charging wire cleaning motor normal direction signal; when '1', the wire cleaner moves toward the rear.
[2] Transfer charging wire cleaning motor reverse direction signal; when '1', the wire cleaner moves toward the front.

SERVICE MODE:
COPIER> ADJUST> HV-TR> TR-N1
(adjusting the transfer charging current output for the 1st side of a duplex print or for a simplex print using plain paper)
COPIER> ADJUST> HV-TR> TR-N2
(adjusting the transfer charging current output for the 2nd side of a duplex print using plain paper)
COPIER> ADJUST> HV-TR> HVT-TR
(entering the offset value of the transfer high-voltage output of the high-voltage unit)
Enter the value indicated on the label attached to the new high-voltage unit if you have replaced the high-voltage unit or initialized the RAM on the DC controller
PCB.
COPIER> ADJUST> HV-TR> D-HV-TR
(entering the offset value for the transfer high-voltage output of the DC controller PCB)
Enter the value indicated on the label attached to the new DC controller PCB if you have replaced the DC controller PCB or initialized the RAM on the DC controller
PCB.
COPIER> FUNCTION> CLEANING> WIRE-CLN
Use it so that the machine automatically causes its wire cleaner to make 5 round trips if you have replaced the primary charging wire or the transfer charging wire.
COPIER> OPTION> BODY> W-CLN-P
Use it to set the interval of automatically cleaning the pre-transfer charging wire in terms of the number of prints.
COPIER> OPTION> BODY> TR-SP-C1
(switching over the transfer/separation output value for pickup from the right deck)
