SPC messgae on C6530

Re: SPC messgae on C6530

The drum potential sensors are mounted on the metal bracket that swings down over the developing unit(s). There is a plastic snap release at the rear that allows each bracket to swivel up towards the front. No major disassembly of the imaging drawer is required (not that that stopped me the first time).

Which one needs cleaning? Check the following locations for abnormal sensor readings: 05-2780-0, 1, 2, 3 and 08-2560-0, 1, 2, 3. Normal values = 0. Abnormal values = 2 or 3).

Clean SPC for the desired color, and check that shutter works properly. To reset error: 08-2560-0, 1, 2, 3 set to 0.

Black drum potential is low , I think the shutter is not opening on the potential sensor. Where is the shutter located ?
