xerox wc5222 - gray copy

[savi0r]

Hi guys. I have a problem with this machine. Some mice broke into it and now when i try to make a copy, when it comes out, the copy is grey and the writing on it is very low visible. The print is the same. If i stop the proces half way, the drum is totaly dark.Some guys told me that it could be the HVPS. Any ideas? Thanks

Hi. I found what the problem is. The mice torn down the wiring from the hvps.

clean very well all electronic pcb (mouse urine is oxidized) and spread some alcool over (or nail polish).
