imagepress 1110 E261-0001-05

[mabawser]

hello,

I currently have an imagepress which throws up the above code on warm up. The trip switch on the PSU for the fixer heater PCB keeps tripping. I checked the voltage from the fixer heater power supply to the ac driver board and the proper voltage was there. On that basis and from a bulletin I found I have ordered and returned and fitted the ac driver board but the same fault still persists.

obviously I have checked the fuser and all seems good. if we switch the machine on without closing the door it obviously doesn't complete the circuit and doesn't give the error or trip the switch but as soon as everything is closed and it goes into initial warm up it trips the switch and gives the error (once it tries to complete everything).

Anyone got any wisdom they could throw in my direction? I have seen people mention fixing lamps but they seem good and the fuser wasn't worked on prior to the code so I doubt it is anything anyone had done while working on the machine. I am hitting my head against a wall here. Could it be the fixer heater PCB or even the DC controller???

any help would be greatly received.

cheers

circuit breakers on the rear of the machine
ensure that both circuit breakers are on to allow proper voltage to fixing assembly.

CANON
E261-0001-05 Error Code is displayed.

The code is defined as an error in the zero-cross signal. This code relates to the Fuser Assembly and the assumed cause per the Service Manual states; when the heater is on, the zero-cross signal is not detected.

Workaround :
After a close inspection of the fuser assembly it was found that the Pressure Roller lamp was bad. The insulation of the lamp cable had been pinched to ground while servicing the Fuser. The lamp was replaced, but the code persisted.

In this case, it was found that the AC Breaker on the rear of the machine had tripped from the wire touching the frame of the Fuser Assembly. This generated the E261-0001-05 Error Code. The Breaker is located in the lower right rear quadrant of the machine. The Circuit Breaker was reset to resolve the error code.

The picture below depicts position of the breaker.

POINT TO NOTE FOR TECHS

E261

The most common cause of this error is missing or improper voltage to the fixing assembly. The fixing assembly is supplied by a proprietary 208vac, 30A circuit.
If the 208vac is missing or not in the correct voltage range, the E261-001 will be generated. Check the wall outlet for proper voltage, make sure the circuit breaker is toggled to the ON position and that 208vac is present at J2001 of the AC driver. The diagram below provides information on how to properly measure a NEMA L 14-30 outlet.

thanks teckat,

I have access to these bulletins but nothing so far has helped find the fault.

so far I am at a loss.

the trip switches are fine to start then the one pictured trips.

was there any work on External Heat Roller Assembly ? or Fixing Unit recently

No it hasnt been worked on at all for weeks and the last call had nothing to do with the fuser area at all either. This was the fault I was called in for. The fault doesnt seem to have been caused by anyone working on it previous.

Greetings, any progress on this call from 2009. I had a upper roller pill its skin and it started doing this code. swapped fixing units did nothing
