I have many machines and studio-520,600,720,850 with the following problem:

The machines are having problems with the merger. Are stops in five minutes so ready copies and prints but not fix.

Sorry for the english but I'm using a translator. I'm from Brazil. I appreciate the help of you's.

I can not understand your English - may be it is me.

Is there any kind of code - call for service (C..., F....), paper jam (E....)?

[marcelo_canon]

There's not the machine code. And not enter into standbay.

did upgrade with jig. I copied the values of the modes of service 05 and 08 a machine that works.

Did You mean that machine can not go to ready status - READY on the display. And showing warming up...?

I think it is the fuser and I would check the tension screws are all the way down and the shipping screws are removed. Otherwise I would check the thermistors.

[marcelo_canon]

fuser was replaced completely, the heater control board. What he decided was the replacement logic board. I wonder whether it was possible to repair plate to be logic board.

check fuser male /female connector for damage,format hdd,check harness running under fusing unit to lwr rear connector from ih board

Do you mean that the machine does not reach ready state ?
