Dear
Its related to the fixing temp. do the error clear on service mode. then check the fixing film assy. heater circuit contact points for corrosion. Replace it.
Thanks.

Fixing film assembly may need to be replaced if error cannot be cleared. Fixing error codes should be reset by a professional only. Fuser assembly must be examined before resetting the E000, E001, E003 and E007 codes. Enter the service mode this way: Press "Additional Function" key, Press "2" and "8" simultaneously, press "Additional Function" key again. Go to COPIER----FUNCTIONS-----CLEAR----ERR. Here your tech can reset the error codes. Then turn machine off & on again.
