Is this the same fault from a week ago? Are the image units chipped? Is the toner OEM? Has the optics been cleaned? You need to do toner add before you do reset and stabilization followed by the grad adjustment. Make sure that the image that is printed (for the adjustment scan) is of good quality or you are wasting your time! When you have got the settings witin the specs switch off the unit and power up again. Do a test printout from the user mode. If your copy/print quality goes bad after a few copies I suspect a stabilizer problem or old IUs.

Hi there!
Ive had asimilar problem but the customer uses no original KM-toner and the transferbandunit was to old (not by prints but time!).
With the new transferunit it became better odd the OEM-toner.
