[Error Code] Ricoh MP C4000 - error code SC582

[Guest]

Our MP C4000 copier comes up with error code SC582. It will only work in Fax mode and Scanner mode. I'm guessing that it has something to do with the Fuser, has anyone got any more definite ideas?

IH inverter current error at power on
The output current from the IH inverter does not reach the proper value
when the IH inverter turns on.

��

Disconnected power input terminal 1 and 2

��

Defective IH inverter

��

Defective IH coil unit

��

Defective fusing unit

1. Check the power input terminals 1 and 2.
2. Replace the IH inverter.
3. Replace the IH coil unit.
4. Replace the fusing unit.

You are on the right track. It is either the fuser or the inductive heating coil. the fuser can be replaced as an entire unit, but the IH coil takes a trained technician.

to isolate this problem, remove the two springs from the fusing unit. let the machine run without it(it will release the tension). if no sc582,then you have to thoroughly lubricate the the fusing unit.

Re: Ricoh MP C4000 - error code SC582

The IH coil has a thermostat mounted in the center. If the thermostat open you will get SC 582 on power up. Even with a new IH coil, pressing the black center of the thermostat will cause it to open. Check CN 982 pin 1 to 2 for continuity to the thermostat. If pin 1 to 2 is open, the thermostat is open. Try jumping pin 1 to pin 2. If this allows the machine to power up, the thermostat is open. Order another IH coil, check the thermostat with your meter before installing, and be careful not to press the center of the thermostat while installing it. Due to the cost of the IH coil, you might try to find proper value Thermostat or thermofuse to fit it.
