Its your fixing unit or sometimes called a fusing unit. The section that gets hot. Sometimes the film tears or it just gets old. You may have to have the fixing unit replaced.

common problem and connect proply

That is best bet since it appears that your print head is fubar and Canon charges a fortune for them. Cheaper to get a new printer with warranty.

That's was a miraculous!!!!! My canon Image Class D860 is brand new now after following the steps.

1. Hit Additional Functions Key
2. Hit # key
3. Arrow to number 7, Printer and hit Set
4. Arrow to number 4, Printer Re-Set and hit Set.
5. Yes, re-set printer (hit minus key - back arrow).
6. Unplug the machine and plug it back in.

This just worked for me on a D860
