U NEED TO INVESTIGATE
the input/output ports of the DC controller PCBs.
COPIER>I/O>DC-CON<DC-CON (5/7)>
P020 xxxxxxxxxxxxxxxx=runs from left to right 15>0
ADDRESS=P020
BIT-
0- zero-cross signal -
1- heater trigger 1 signal 0: ON
2- heater trigger 2 signal 0: ON
3- heater error OFF signal 0: error
4- not used
5- not used
6- M9 registration motor phase A pulse signal -
7- M9 registration motor phase B pulse signal -
E261 0000
The intervals of zero-cross signals deviate from the tolerance range while
the fixing heater is supplied with power.
Main cause The wiring is faulty (short circuit, open circuit). The main power supply
PCB is faulty. The DC controller PCB is faulty.
Making Corrections
1. Connectors
Are the connectors J205 on the main power supply PCB and the connector
J308B on the DC controller PCB securely connected?
(zero-cross signal: J205-7 <-> J308B-1)
NO: Connect the connectors securely.
2. Main power supply PCB, Main controller PCB
Try replacing the main power supply PCB. Is the problem corrected?
YES: End.
NO: Replace the DC controller PCB.
