The non-contact thermistor is installed so that there is a gap of 1 mm between it and the surface of the hot roller. To maintain this gap of 1 mm, do not remove the non-contact thermistor, and do not remove the hot roller and the pressure roller, which cannot be removed without the removal of the non-contact thermistor.

Replace the fusing unit when the non-contact thermistor, the hot roller, or the pressure roller are broken.
