Its printing the last page over and over because the printer is sensing a jam. Based on the error codes it could be the drum maintenance clutch, p/n 650428800.

Thanks Marty but i have already replaced this part as this fault was happening all the time. After replacement it worked for a couple of weeks. Now it does this intermitantly. So i reinstalled and cleaned everything i could find that looked like it needed cleaning and still it happens. Any other suggestions would be appreciated.
Thanks in advance.
