Savin 9090 print quality problems

[slimslob]

I checked the continuity from shaft to frame while I had the drum unit out.

I use diode check for that.

The was none from chassis to shaft.

I assume that tsb#039 is some sort bulletin.

I have no Ricoh support, and do not know a way to access the bulletins.

You need to use resistance not diode check. Diode check does not show resistance value.

So a little update...

I replaced the entire drum unit to no avail.

I opened up the back of the mfp and watched the fly wheel turn with a few prints and noticed it would slip.

It was missing the set screw on the back of the drum shaft.

Not sure how a client got a machine without a set screw.

I put in the set screw and voila! It works.

Thanks for your help everyone.

I feel dumb
