Had non-Canon toner cartridges that work fine before the move. After the move Canon said not Canon and would not print (make lots of clinking noise). Replaced all 4 cartridges with original Canon start ones and the same think is happening.
Time for a new printer?
I rushed my description, so here's Canon's message: "Cartridge Communications Error"
A counterfeit or non-Canon cartridge may be in use.
But they are original Canon starter one.
It looks like something is wrong with the hardware on the MF743Cdw or the chips on the toner cartridges that provide the cartridge information. In this situation, I would suggest contacting support at 1800-652-2666. They would be happy to check the hardware to see what is going on or what is going on with the cartridges. If the printer needs service, they can also provide your service options.
If this is a Canon MF743Cdw, I vaguely remember an option to allow the use of non-Canon toner cartridges. Off the top of my head, I can't remember the path that leads to the option, but one does exist.
