Ricoh MP 1600 dark copies in the am

[slimslob]

the copier is not near a window...but the drum ground does sound pausible..I'm not sure where the drum is grounded, I see on the rear drive unit, am I looking for a ground strap attatched to the main drive unit?

Faulty drum ground is a major cause of dark background. It is a small metal contact plate on the main drive unit housing and has a lead connected that goes to the HVPS.
