My Canon MF731C/733C is producing poor quality documents when printing–– ink levels are good, I updated the firmware and went through all of the cleaning/maintenance prompts on the device and yet anything I print regardless of whether or not it is B&W or Full Color is coming up with smudging and the ink is faded on other parts of the documents. There is also a blue line that is appearing on some documents (see attached test print page). Not sure what else I can do to fix this!
Thank you for any and all help.
