In my office we have a laser printer, sorry don’t know the brand. It consistently prints out pages that seem to have black dust and smudges on them. We thought it was the toner, but that doesn’t seem to be the problem. My co-worker tested the toner cartridge on the printer he has at home, and the pages came out fine.
Is there something else we can try? I need to use this printer for a big job and it’s really annoying that the pages come out looking so crappy.
