HP Laser Printer Problem

[wantabe2]

What causes black marks on the output of a laser printer? It is always on or near the same spot on the paper when it comes out.

Probably toner on a transport roller. Sounds like time to do a clean up inside then with new cartridge and defuser.

Probably time for a fuser kit. How many pages are on the counter? If it's close to 100K, it's fuser time.
