This is a new one for me, hoping somebody else has seen it and can offer insight:
Received a used C220 with ~100k. Internal prints look good, ADF prints look good (aside from some skew), but copies off the platen have significant background/shadows. Strangely, if you copy a 2-sided original off the platen, the 2nd side appears as a shadow in the print. Almost looks as if the scan lamp is too bright, allowing the 2nd side to show through. There are no lamp adjustments, as far as I can tell. Scan reference strip is clean, mirrors and lamp are clean. Performed total clear, reset copy settings to factory default, loaded latest base f/w. No change.
I've seen funny things happen with bent scanner frames, but this one looks pretty square to my eye. SKMBT_C22015121020240.pdf
