My test printer for 53A/x carts is a 2014n. All of a sudden I'm having fusing issues. I've tried different vendors toners as well as OEM with no change so I've narrowed the problem down to the machine. As this machine has only done about 20K I'm dubious that the fuser would have packed it in so soon. I've heard of formatter issues with these machines and was wondering if anyone has come across this before.
Changing the media type to heavy cardstock improves the fusability only marginally.

Maybe I've answered my own question here...

Any thoughts?
