Hello, I am looking at an 5210n that will leave a toner shadow approximately 2 inches wide running top to bottom in the middle of the printed page. I was told the printer had recently been moved. When I looked at it, the first few (1-3) prints looked OK and then the shadow would show up. A corresponding layer of toner can be seen on the PC drum. They have two of these printers. So I swapped toner carts. between them. No change. Also swapped the charge and transfer rollers. NC Cleaned all contacts. No change. The image defect stayed with the original printer. I swapped out the HVPS and the shadow was still there. Less dense but still there. The image cleaned up with print jobs. I get a call the next day and the vertical band is back. CU shuts it down for the weekend. Works fine today. ????? I don't want to look a gift horse in the mouth, but what gives do you think? Any thoughts MAY allow me to sleep tonight!
Thanks,
John
