I have 2 Kyocera FS-4300DN printers in an office installed in October 2013 with 225K on each as of today. I know the yield for all the maintenance parts is 500K. Well, both of the upper heat rollers look terrible on the right half of the rollers. It's causing poor fusing and dirty prints down the left edge of the page. I plan on returning these for warranty, but has anyone seen this on these printers? If it were one printer, that's one thing, but both of them are doing it at around the same time.
They run plain, letter paper only. Firmware is up to date.
Other than this issue, these have run like a champ.
