3.11.2 Gap adjustment for pressure roller thermistors
When any of the parts shown below was replaced or removed, check the gap between the pressure
roller thermistor and the pressure roller, and then adjust it if required.
• Pressure roller
• Pressure roller thermistor (center/side)
Notes:
• Wait until the fuser unit is 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 pressure roller and the pressure roller thermistors 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.
