I'm having the same problem in all color series( 250,300,400,500)
machine updated with the latest version
according to new update that has not come, fix the issue.
also accumulate large amount of black toner developer unit
Machines with less than 100k even newly installed.
I'm fixing for now with color calibrations.
the question is what happens to someone else.
For background check U131
If the Control Voltage differs from the Default Voltage by more than 25, the DV unit will probably need replaced. In some cases DV refresh may take care of it. This is usually only the case with black DV units.
I agree with tmaged. Also run some U089 gray internal test patterns. If you see a pattern that repeats at 38mm intervals replace the associated charge roller. Then calibrate. =^..^=
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.

Maybe I missed something... but v6.03 is pretty old, and I know a bunch of fixes were made for CQ weirdness in v9/9.01, including some new options for toner control, BW/Color usage balance, and AC calibration.
Yeah, I missed something... like the fact the thread was 6 months old. :LOL:
