Contents: Broken fixing heater wire • In fixing warm-up, the time to reach 50°C/122 °F exceeds 13.5 s, the time to reach 100°C/212 °F exceeds 10 s, the time to reach the primary stabilization exceeds 10 s or the time to reach the secondary stabilization exceeds 24 s.
Causes: Poor contact in the thermistor connector terminals. Check procedures/corrective measures: Check the connection of connector CN4 on the power supply board (KP-5059) and the continuity across the connector terminals. Repair or replace if necessary.
Causes: Thermistor installed incorrectly. Check procedures/corrective measures: Check and reinstall if necessary.
Causes: Thermal cutout triggered. Check procedures/corrective measures: Check for continuity. If none, replace the thermal cutout.
