Gap adjustment for fuser belt thermostats

When any of the parts shown below was replaced or removed, check the gap between the fuser belt
thermostat and the fuser belt, and then adjust it if required.
• Fuser roller
• Fuser belt
• Heat pipe roller
• Fuser belt thermostat
Notes:
• Wait until the fuser unit has completely cooled down, and then start the adjustment.
• Place the fuser unit on a flat surface, confirming that its 4 legs are securely grounded.
• Measure the gap while pressure is being applied to the pressure roller with the spring force.
At this time be sure that the pressure screw is securely tightened so that it will no longer be
turned.
• Be sure not to damage the fuser belt with the gap confirmation jig.
• Adjust the gap while the pressure roller is released from the fuser belt.
• If the fuser unit is not installed to the equipment after the replacement or adjustment but must
be stored as a unit for a long time, be sure to leave the pressure roller released from the fuser
belt.
