I would suggest contacting support again to process a warranty exchange for the MF641.</P> Wed, 22 Mar 2023 20:06:29 GMT Hector 2023-03-22T20:06:29Z https://community.usa.canon.com/t5/Office-Printers/Canon-ImageClass-MF641CW-Not-Printing-Black/m-p/409474#M18676 <P>Hello,</P><P>I have purchased a new laser printer and can't seem to get any black text to print and on top of that, every page comes out with a gray shading. Waiting for Canon support on the phone and they deemed it an issue with the black toner. New toner came in and was installed but still having the same issue. Colors are coming in as expected but on a gray background. Printer is wirelessly connected. Any thoughts?</P><P>&nbsp;</P> Fri, 10 Mar 2023 19:49:07 GMT https://community.usa.canon.com/t5/Office-Printers/Canon-ImageClass-MF641CW-Not-Printing-Black/m-p/409474#M18676 enzo5190 2023-03-10T19:49:07Z https://community.usa.canon.com/t5/Office-Printers/Canon-ImageClass-MF641CW-Not-Printing-Black/m-p/411049#M18820 <P>Hello Enzo5190,</P> <P>If you continue to have the same issue after replacing the black toner cartridge, it looks like there is something wrong with the hardware.
