Ricoh Aficio 1045 troubles

[Guest]

Went to the client and changed the drum and blade because was streaking. Removed the charge roller and cleaned it. Machine has around 150k on it.

The problem is when I put the unit back together I get a gray background. There is no print at all- just a gray background. I have tried to re-assemble the unit, checked the contacts etc. Also am getting a SC350 code ID sensor?

Check the little drum ground on the bottom right back side of the drum case.

If you can not obtain any positive results after the other 2 good advices I suggest to slide in a new PCU unit, especially if you can not get rid of SC 350

if you've used a vac on the pcu near the id sensor then it's probably toast. static discharge does these in immediately.
