If the thermostats trigger an alert, the thermostat requires replacement.
A fusing exit sensor, located between the hot roller and paper exit roller, detects paper jams inside the
fusing unit.
Pressure Roller
Heavy springs [A], attached to pressure arms [B] below both ends of the pressure roller [C], keep the roller
pressed against the hot roller [D] above.
Release the springs [E] in order to release the pressure from the rollers for maintenance.
Two holes [F] are provided on each pressure arm for the springs.
• Normally, the springs should be attached to the lower holes. Attaching the springs to the upper holes
exerts less pressure on the hot roller. Attach the springs to the upper holes only for especially thin
paper.
