I have a realtively new Phaser 6500 that at 4000 pages printed has started to sqeak loudly. I shut the printer down and let it rest. After an hour, the squeak was gone - but the print quality is horrible. Everything comes out motteld and splotchy, and musch of it is barely fused. Anyone else experience this problem? I suspect the tranfer belt has malfunctioned. Could this be on such a new machine?
