10-100-00, 10-200-00, 10-300-00 Fuser Thermal Errors RAP
10-100-00 Open Fuser Circuit Error. The Fuser did not warm up during operation. Thermistor
did not connect or contact point is not coupled tightly in power on.
10-200-00 Fuser Low Heat Error. The Fuser could not reach proper temperature, or improper
thermistor reading.
10-300-00 Fuser Overheat Error. The Fuser temperature has risen to a very high degree. If the
temperature of the Heat Roller increases above the toner-fusing-temperature, parts of Fuser
may be thermally degraded. The thermistor is disconnected or providing erroneous readings.

Initial Actions
• Reseat the Fuser.
• Check for obstructions or damage to the Fuser connection.
Procedure
Switch off the electricity to the machine. Disconnect the power cord from the customer
supply while performing tasks that do not need electricity. Electricity can cause death or
injury. Moving parts can cause injury.
Do not touch the Fuser while it is hot.
Check the Fuser connector for dirt or damage. The connector is clean and undamaged.

Initial Actions
• Check Fuser Heat Roller movement.
• Check for obstructions in the Fuser.
Procedure
Switch off the electricity to the machine. Disconnect the power cord from the customer
supply while performing tasks that do not need electricity. Electricity can cause death or
injury. Moving parts can cause injury.
