You can try reseating the black toner cartridge or trying several fixing assembly cleanings. If that does not resolve the issue, you can try replacing the black toner cartridge.</P> <P>If the smudges still appear after replacing the black toner cartridge, It looks like the printer needs service.

I have tried all the self-maintenance products on the machine. Any ideas?<span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="Cannon Printer example.jpg" style="width: 772px;"><img src="https://community.usa.canon.com/t5/image/serverpage/image-id/36782i6D529CD142153D7F/image-size/large?v=v2&amp;px=999" role="button" title="Cannon Printer example.jpg" alt="Cannon Printer example.jpg" /></span></P> Tue, 18 Oct 2022 13:56:12 GMT https://community.usa.canon.com/t5/Office-Printers/imageClass-MF733CDW-printing-error/m-p/390386#M17320 BloomBS 2022-10-18T13:56:12Z https://community.usa.canon.com/t5/Office-Printers/imageClass-MF733CDW-printing-error/m-p/393158#M17507 <P>Hello BloomBS,</P> <P>The image looks like there is toner on the fixing assembly or there is something wrong with the black toner cartridge.
