  • Code: C0500
  • Description: Fusing Warm-Up Failure (Main)
    • The Fusing Roller Thermistor does not detect the required temperature within 30 sec. after a warm-up cycle has begun; therefore, the copier does not complete the warm-up cycle. • The temperature of the Fusing Rollers does not reach the required level even after the set period of time has elapsed during a warm-up cycle.
  • Remedy: 1 Check that the Fusing Roller Heater Lamp comes on when the Power Switch is set to ON, and correct or replace as necessary. 2 Check that the Fusing Roller Sub Heater Lamp comes on when the Power Switch is set to ON, and correct or replace as necessary. 3 Check the installation of the Fusing Roller Thermistor and the Fusing Roller Sub Thermistor, and correct or clean as necessary. 4 Check the operation of the Fusing Roller Thermistor. Remove CN80 (4P), and then check that the resistance across CN80-2 and - 3 on the Thermistor is infinity. 5 Check the operation of the Fusing Roller Sub Thermistor. Remove CN81 (4P), and then check that the resistance across CN81-2 and - 3 on the Thermistor is infinity. 6 Check the continuity of the Fusing Roller Heater Lamp.
