Hi, have someone a idea how to fix this problem?
Have a look on the jpg. Format A3
There are stripes every 5mm... on black print, on half tone. I mean the tiny darker stripes not in feed direction.
What i have done to fix...
New Drum, DV black, transferbelt, transferroller, clean the laserunit (disasembled and cleaned), played around with the voltages... clean the contacts from drum, dv and trans-belt-roller.
Nothing helps.
After switching back the old units, the first print was better, after the stripes come back darker.
Can it be a mechanical problem from the drive?
or should i try to change the boards? the prcb or the HV?
