Description: Fixing unit failure (abnormal Warm-up)
Remedy: 1. The rated voltage of the fixing unit installed in the printer differs from the line voltage. Action: Replace the fixing unit. 2. The thermistor is dirty. Action: If the thermistor contact area of the upper fixing roller is dirty, clean it. 3. The thermistor is not installed correctly. Action: If the thermistor is not evenly contacting the upper fixing roller, re-install the thermistor correctly. 4. The thermistor wire is broken. Action: Turn the power OFF and remove the fixing unit. Measure the resistance between the fixing unit connector J50B-5 (FSRTH) and J50B-4 (GNDTH). If the resistance is not between about 190kom and 290kom (room temperature of 25°C), check the wiring from connector J222 on the DC controller PCB to the thermistor. If it is normal, replace the thermistor. 5. The main heater wire is broken. Action: Remove the fixing unit. If there is no continuity between the fixing unit connector J50-3 (FSRN1: the upper right terminal of the left connector) and J51-5 (FSRN2: the upper right terminal of the right connector), replace the main heater. 6. The sub heater wire is broken. Action: Remove the fixing unit. If there is no continuity between the fixing unit connector J50-4 (FSRL1: the lower right terminal of the left connector) and J51-6 (FSRL2: the lower right terminal of the right connector), replace the sub heater. 7. The thermoswitch is open. Action: Remove the fixing unit and wiring cover. If there is no continuity between thermoswitch terminals, replace the thermoswitch. 8. The fixing unit drive circuit is defective. Action: Replace the power supply unit. 9. The DC controller PCB is defective. Action: Replace the DC controller PCB.

Description: Fixing unit failure (abnormal high temperature)
Remedy: 1. The thermistor has shorted. Action: Turn the power OFF and remove the fixing unit. Measure the resistance between the fixing unit connector J50B-5 (FSRTH) and J50B-4 (GNDTH). The connector J50B is the upper terminal of the left connector. If the resistance is 1kom or less, check the wiring from connector J222 on the DC controller PCB to the thermistor. If it is normal, replace the thermistor. 2. The fixing unit drive circuit in the power supply is defective. Action: Replace the power supply. 3. The DC controller PCB is defective. Action: Replace the DC controller PCB.

Description: Scanner motor malfunction
Remedy: 1. The scanner motor drive line connectors are loose. Action: Reconnect connector J1 on the scanner driver PCB, intermediate connector J18, and connector J207 on the DC controller PCB. 2. The scanner motor driver is defective. Action: Use the printer driver tester to rotate the scanner motor. If it does not rotate, replace the laser/scanner unit. 3. The DC controller PCB is defective. Action: Replace the DC controller PCB.

Description: BD malfunction
Remedy: 1. The BD signal line connector is loose. Action: Reconnect connector J6 on the BD PCB and J206 on the DC controller PCB. 2. The laser drive signal line connectors are loose. Action: Reconnect connector J1001 on the laser driver PCB, and connector J202 on the DC controller PCB. 3. The laser/scanner unit is defective. Action: Replace the laser/scanner unit. 4. The DC controller PCB is defective. Action: Replace the DC controller PCB.
