    What is the final value? I've had them go into the 80's when replacing developer but still have good quality. What else have you tried? How many copies on the drum?

    Good luck

      Light areas along the rear of the original/copy, within 30mm of the rear edge of the copy, print or facsimile at 94mm intervals.

      Something like this? Replacing the developing unit helped for a while. Leveling up the machine helped a little, but neither completely cured it. This machine was replaced, but I would have replaced the main drive unit next. =^..^=
      If you'd like a serious answer to your request:
      1) demonstrate that you've read the manual
      2) demonstrate that you made some attempt to fix it.
      3) if you're going to ask about jams include the jam code.
      4) if you're going to ask about an error code include the error code.
      5) You are the person onsite. Only you can make observations.

          you can push a litte toner in dv and print (carefully not too much just 2 spoons again and again if that not good) when you have good quality so you run again 25-2 that will be better

            i flashed imagistics firmware to these units and now my customers nothing to complain about printing quality issues.
            i faced this problem when flash to the latest sharp firmware, pcu 2.01.00 this version ll reduce toner density in dv box.
