MX-5141 image issue
Customer has a MX-5141 with around 90k black and 50k color. All supplies have plenty of life left. Machine was shipped to them from another office so it's not one they purchased from us. Don't know how long they've had it but it was supposedly working fine until someone thought the file size of the scans was too large and got into the settings and tried to make the file size smaller. They don't know what was done or if from webpage or console and the person who did it is no longer there.
The issue is that if you make a copy OR scan an original to your computer the image is slightly out of focus - best way I can describe it - and color copies/images look blurred for the top two thirds of the image while the bottom third is ok. If you rotate the image on the glass then the opposite portion of the image is affected. The problem is on the rear frame side. To illustrate if you copy the Sharp sunflower test chart with the multicolored map with the heavy black stripe running across the width of the page at the rear frame side when the image comes out on paper or computer screen the heavy black band is not black but green then black then red but is the same width as the original. With a mainly text color document the top two thirds of text are greenish-black while the bottom third is a nice solid black.
I would be inclined to think the problem was a drum phase issue but self prints at the machine are flawless as are print jobs sent from the computer - as long as they are not something that was scanned in first.
Drum phase calibration, color calibration, and CCD calibration have been run just to be sure but as I said self prints and prints from computer are flawless. The problem only shows up copying or scanning. Any ideas appreciated!
