Printer: MF731cdw
OS: Windows 10 (because the print quality from my Mac is horrible and I gave up trying to fix it)
Drivers: Latest drivers from Canon website
Firmware: Latest from Canon website, dated 3-7-19
Initial Problem:
My prints started coming out faded down the entire left side of the sheet. So I decided to start with running some of the maintenance options.
- Auto Adjust Gradation, both Full and Quick, sound like they are running but a few seconds later I get the error “Could not perform correction”. Adjust Copy Image displays the error immediately.
- Correct Print Color Mismatch - Works.
- Clean Fixing Assembly (Rdc Back Side Staining) - Error “Could not perform cleaning” immediately displayed.
- Clean Fixing Assembly - Error “Could not perform cleaning” immediately displayed.
- Clean the ITB - Works
- Clean the Feeder - Works
The black toner is almost brand new, but the color toners were all at the ‘Prepare new toner’ stage, so I replaced all the color toner with genuine Canon toner. Now it’s worse and I still can’t run any of the maintenance and cleaning jobs listed above. I know it’s recognizing the new toner because they are showing up correctly (mostly) in the portal. The blue and pink are at 100%, but yellow is at 90%. No idea how I could have used 10% of the yellow toner since I put it in.
I just don’t know what to do at this point. Now the print quality is not usable and I can’t run many of the jobs that I assume would correct the problems? I’ve had this printer for about a year and a half and am sure I have spent more time trying to fix this printer than I have actually getting good quality prints. I’ve been in the tech industry for over 20 years and have never seen a printer that was so hard to work with.
