[Error Code] Bizhub pro c500

[CKiiza]

I have an error code SC46-25 and that's because the machine's lamp is not turning on. None the less after about two hours or so the machine usually starts up properly and the lamp works well though if it remains idle for some time it will fail to start the lamp again for quite some time and the much later on it will start again.According the user this problem started after the machine was set to power save mode and on waking from the power save mode the machine displayed the code. and has continued since.
Is there a way of resetting this condition?
thanks for the help.

• The exposure lamp intensity is excessive.
• The exposure lamp does not light.

Thanks for that. seen and confirmed that the exposure lamp doesn't work so the error code is displayed. the trouble is that this problem keeps coming and going off.

It's a shot in the dark, but if I had to bet, I'd take a guess that the lamp inverter board is starting to fail.

That was my guess too...quite likely, considering the age of the model.

Thanks for that. I assume that the Inverter board will have to be replaced. is there a way to repair it at all coz I don't have a replacement immediately?

If you can figure out which component is failing, I would assume it is possible...of the the solid state devices on the board is most likely...maybe a failing capacitor or an issue with the coil. Hell, it could even be as stupid simple as cold solder connections, which in retrospect, is the most likely cause.
