Our Xerox 7556 is producing light copies, with even some light fading when copying from the document feeder. When printing to the device, the output is excellent wtih no issues.
I tried cleaning the scanned glass, without much impact. The client scans "tickets" from the warehouse that have white dust on them. They sometimes blow the debris off with an air cleaner, but it seems as though this is likely effecting some sort of optic within the scanning process.
Any ideas on how to work on correcting this issue?
