Is the paper settings correct on the printer?
If not could be the fuser maybe it's overheating
Try this run 10
then let cool off and run 10 again
I know may not be the best option but double check the paper settings etc.
Hello Gabiene, thank you very much for your reply.
I did it, but i can not see anything. When i start print and printer is cold - first 10 sheets for example, it is without problem. When printer is warmed up - for example 15 sheets and up, it start scratch paper. I think it is from any static or rolling thing on the way from fuser. See one more photo.
Take out the fuser adn look at the fuser roll. Rotate the roll to see if it have scratches on it.
could you help me please? When I print on 350g paper in my Xerox Phaser 7800, i have srcatch in paper. Approx first 10 is ok (until it warms up), but when printer is hot , in sheets are scratches. Something engraves into paper. Photos attached. Many thanks for reply.
