Hello there folks,

I tried everything to fix this error. When I turn on the machine almost imediatly i get SC34-01. At the service manual it says: "TH1 (fixing temperature /1) detects more than 220°C for five consecutive times in 1 second cycle. ".:confused:

I've changed the TH1 themistor, the Print Control Board, DCPS (DC power supply), TH2 thermistor, and the L3 and L2 fixing lamps. :mad:

I've changed the hole internal unit (ADU and everithing), and putted in to another machine and get's the same error.

Does any one has a clue?

Thanks

BC

You did reset the memory switch? 3-1 to 0. If not you replaced alot u didnt have to.

I did reseted the DIPSW 03-1 from 1 to 0. But when I turn the machine off and on again i get the same error.

Sorry no offense had to ask. The only parts I have had to replace for fuser codes are the temp sensors, thermostat, or lamps, which you have done them all. Does the fuser heat up? When replacing the temp sensors(I think there are jigs but who cares) are the sensors making contact with the roller?

That's the problem the fuser isn't heating. When I turn on the machine the lamp's doesn't even turn on and I get the error code.

I replaced the thermistor using the jigs, the TH1 isn't in contacting the roller and the TH2 is.

Check the plug on the fuser and the plug in the back of the machine for broken blades.

-Maybe a bad contact ,between the fuse unit ,and the machine...
-Look the power connector-could be calcined...

Hello every body. I finally fixed that error. The Main Bord had a short circuit with the diode that controls temperature. I found this becouse i sent the board to a eletronic tecnitian that's a friend of mine.

Thanks for replying.
