Hi got this from another site , not sure if it's for your model though ( sharp SF 1118 )
Open right side door and check for a jam in the fusing unit (the one that is normally hot). Remove jam carefully. Hit P * C * and enter 14. Push the start button like you are making a copy. Machine should reboot and code should not return. if it does, you may have a dirty themistor, or blown lamp.
TRY HERE IF THAT DON'T WORK
