Dislikes: Does the mark on the drum rub off or is their a nick on the drum?
Did you replace the dev unit or just redev it? if you just re deved it then its possible to still have toner debris in the unit which will contaminate the charge roller.

Changed the drum again and whole transfer belt unit(on inspection the old one looked fine) ...good for awhile...apeared again.
The dot is always visable on the drum...looks like mechanical defect...like little cut...
Its always only on magenta drum...
Any suggestions?
THANX!!!
replace the PCU and toner
I replaced the PCU
The nick is on the drum...can not be whiped off
I also replaced the whole dev. unit,not yust developer...
Toner is the same for all...CMYK
I have problem only with M
Is the screw lock on the front of the PCU cover? Could it be possible it is missing, someone is deliberately taking the drum unit out and damaging it?
It's 106 miles to Chicago. We've got a full tank of gas, half a pack of cigarettes, it's dark and we're wearing sunglasses.
Hit it.
