The 644cdw Cyan toner ran and was replaced. It now prints very lightly and only on the left side of the page.
I shook all of the toner cartridges, but there is no change.
Printed a picture and it is barely visible on the page.
the printer indicates that all cartridges have ink.
Is this an issue with the fuzer or what?
The issue looks like a problem with the toner or the hardware. In this situation, you can try reloading the toner and checking to make sure all packing material and seals have been removed. After, reseating the toner, you can try cleaning the Fixing assembly. Once the cleaning is finished, you can try printing to see if it works. If it is still only printing on one side, I would suggest contacting support over the phone at 1-800-652-2666 or logging into your MyCanon account to check you service options.
