Sorry the procedure I'd discovered is not working for you.you might want to call Canon (long hold times I know) at 80 to see why your printer will not "Perform the Operation". Hi Firefly1 as mentioned in other 's been awhile since I was here. This did the trick for me, hope others find it helpful, enjoy!

Go to the Home Screen > Menu > Adjustment/Maintenance > Adjust Image Quality > Auto Adjust Gradation > Full Adjust > Select ‘OK’ (it will list 4 Steps)… Auto Adjust Gradation - Full Adjust - (This is a more robust sequence than the initial Startup Color Adjustment when the printer was first turned ON.).Next, go to the Home Screen > Menu > Adjustment/Maintenance > Adjust Image Quality > Correct Print Color Mismatch > Select ’Start’ (in the lower righthand corner of the Printer’s Display, and let it do its thing).

Three (3) Steps to Great Color & Deep Blacks – To fix this…I followed this procedure and now the MF740 Series / MF743Ddw is printing like expected…like a champion with full vibrant Color and great rich deep Blacks when printing either B&W or Color. It was very noticeable compared to several Canon Color ImageClass MF730 Series / MF733Cdw printers I had previously installed and configured. Even on Black/Text only prints, it looked almost “Lite-Brown” or like some sort of Lighter Grayscale instead of a “Deep True Black”. I noticed the brand new Canon MF743Cdw was printing what I would call “washed out” Color. How to fix the “lighter looking” / slightly “washed out” printing of a Canon MF740 Series laser printer (Canon Color ImageClass MF743Cdw).
