Prints slightly dark no matter where the contrast control is set. Cleaned corona, no help. Suspecting the drum assy (Dr-100) may have some degraded toner in it which effected the drum. The service manual dont say how to make sure it has the right voltage from the HVPS. Does anyone know about how much voltage ought to be there? I get over 1000V on my Fluke DMM during a test print. Does high output there mean dark copies or vice versa? Have read on google groups this drum unit may have had some bad production runs.
