CHAPTER 13 TROUBLESHOOTINGCOPYRIGHT © 2002 CANON INC. 2000 CANON iR1600/iR2000/iR1610/iR2010 SERIES REV.0 MAR. 200213-178E004 At time of initialization, the ZEROXI* signal of the power supply is notdetected.During temperature control, the ZEROXI* signal does not arrive for 3 seccontinuously.A short circuit is detected in the triac (ASIC; fixing temperature controldrive circuit error).Possible cause Fixing assembly is faulty. (The main thermistor has an open circuit. Thesub thermistor has an open circuit. The fixing heater has an open circuit.The power supply PCB is faulty. The DC controller PCB is faulty.)Note To reset the error, execute the following in service mode, and turn off theand then on the power switch.#7 PRINTER>#4 PRINTER RESET>YES=(*)Remedy1) WiringIs the connection of the connector (CN8) on the power supply PCBand the connector (J103) on the DC controller PCB and the wiringto the fixing assembly normal?NO : Correct the connection and wiring.2) Fixing assemblyTry replacing the fixing assembly. Is the fault corrected?YES : End.3) Power supply PCB, DC controller PCBTry repacking the power supply PCB. Is the fault corrected?YES : End.NO : Replace the DC controller PCB.4) ErrorWith the power switch ON, clear E000 through E004; then, turnoff and then on the power switch.If E000 through E004 is indicated, the RAM on the image processor willretain the error memory of the fixing assembly after the power switch hasbeen turned off an then on. Execute the following in service mode, andturn off and then on the power switch to clear the memory: #7PRINTER>#4 PRINTER RESET>YES=(*).
