Description: Fusing reload failed: Fusing temperature warm-up error
• The fusing temperature doesn’t rise by more than 7 degrees for two seconds; and this happens 5 times consecutively.
The measure is start in 3.5 seconds after activation of the heater. This monitoring will stop in the case of reaching the reload temperature.
Causes: • Defective thermistor
• Power source is out of warranty
Code: 542-003
Description: Fusing reload failed: Time out error
(On the fusing roller inactive) NOT reaching the reload temperature in 25 seconds after starting heater control.
Causes: • Disconnection of Heater After activation of the anti-overheat device
Code: 543
Description: Fusing overheat error 1
The fusing temperature detected by the thermistor is 230°C or higher for one second.
Causes: • Defective the triac (Semiconductor device) • Defective the IOB control board
• Detective the BICU control board
Code: 544
Description: Fusing overheat error 2
The fusing temperature detected by the monitor circuit is 250°C or higher.
Causes: • Defective the triac (Semiconductor device)
• Defective the IOB control board
• Defective the BICU control board
• Uncontrollable fusing condition
Code: 545
Description: Fusing lamp overheat error
The fusing lamp remains on for 12 seconds after starting the waiting mode.
Causes: • Defective thermistor
• Disconnection of Heater
• After activation of the anti-overheat device
Code: 547-001
Description: Zero cross signal malfunction
Detecting fusing contact meltdown
Causes: • Defective the fusing relay (Contact adhesion, Contact separation)
• Defective the drive circuit in the fusing relay
• PSU fuse (24VS) meltdown
• Unsteadiness in frequency of the commercial power source
Code: 547-002
Description: Zero cross signal malfunction
Detecting wrong with fusing contact
Causes: • Defective the fusing relay (Contact adhesion, Contact separation)
• Defective the drive circuit in the fusing relay
• PSU fuse (24VS) meltdown
• Unsteadiness in frequency of the commercial power source
Code: 547-003
Description: Zero cross signal malfunction
Detecting low-frequency wave
Causes: • Defective the fusing relay (Contact adhesion, Contact separation)
• Defective the drive circuit in the fusing relay
• PSU fuse (24VS) meltdown
• Unsteadiness in frequency of the commercial power source
