SC300 on a Aficio SP C222SF

[angelntx]

I have an ancient piece of hardware here that I have swapped the High Voltage power supply board and the EGB with another identical working unit but I still have the SC 300 code returning. We can not order parts for this and the client is pretty admit about getting this back. Am I missing anything?

Check the pressure springs on the PTR assembly. I've had them cause SC300 on an SPC232.

From Gooses Guide

SC 300	High voltage power output error: Defective HVPS
SC 300	High voltage power output error: Defective EGB
SC 300	High voltage power output error: Refer to TSB bulletin #11

TSB #11 has to do with a change for the power pack.

Yes, the satisfying crash from throwing this POS in the bin. Bite the bullet and tell the customer it ain't worth repairing and parts are no longer available. They will thank you for it in the long run.
