Chapter 7
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)
COPIER> OPTION> BODY> TR-SP-C2
(switching over the transfer/separation output value for pickup from the left deck)
COPIER> OPTION> BODY> TR-SP-C3
(switching over the transfer/separation output value for pickup from the cassette 4)
COPIER> OPTION> BODY> TR-SP-C4
(switching over the transfer/separation output for pickup from the manual feed tray)
COPIER> OPTION> BODY> TR-SP-MF
(Use it to switch the transfer/separation output for pickup from the manual feed tray.)
COPIER> OPTION> BODY> TR-SP-DK
(switching over the transfer/separation output value for pickup from the side paper deck)
As necessary, switch over the transfer/separation output value for pickup from various sources of paper by way of correcting various faults:
0: normal (default)
1: prevent re-transfer
2: prevent separation fault
3: prevent transfer fault
