Color pages print fine. Have tried running maintenance cleaning programs to no avail. Have removed tray and cleaned inside the unit. All with the same indications nothing changes.</P> Fri, 14 Apr 2023 17:27:04 GMT mstrbill52 2023-04-14T17:27:04Z https://community.usa.canon.com/t5/Office-Printers/Color-imageCLASS-MF642Cdw-streaks-on-black-and-white-print/m-p/414386#M19052 <P>When printing text or black and white documents I get cyan and blue streaks on the page.

Is it a genuine Canon toner cartridge?</P><P>A few other things to try....unplug the unit for a while to see if it that helps. Next try a factory default of the unit (I believe there is an option to do this in the menu). If neither works, contact Canon Support as the unit may need to be serviced.&nbsp;</P> Sun, 16 Apr 2023 01:10:45 GMT https://community.usa.canon.com/t5/Office-Printers/Color-imageCLASS-MF642Cdw-streaks-on-black-and-white-print/m-p/414718#M19065 dexman335 2023-04-16T01:10:45Z
