MF644 cdw prints with smudges and inconsistent printing (light and dark) . suggestions how to fix?

VINNYSAV — Mon, 14 Sep 2020 20:24:57 GMT

have had my MF644 cdw laser printer for about 10 months with little or no issues. Now i am getting smudge marks on the left side of the print outs both yellow and black smudges. Also, now the printed letters are both dark and light through out the page. Any suggestions on how to return to origional condition that was just fine?

I am using windows 10 and am communicating with the printer via wireless connections.

Thanks for any suggestions....

I have the same problem with a 2-day-old printer. Try this and tell me if it changes the print quality?
