Description: Fuser open thermistor. Hot roll thermistor circuit is open If error code 122.03 displays, the printer detects a problem in the fuser hot roll, fuser hot roll thermistor, system board, or LVPS fuser control circuits.
Remedy: 1 Turn the printer on, and allow it to reach the Ready prompt. Note: The printer may not complete POR and post a 122.03 Error message. Measure the voltage on connector J17-6 on the system board. The voltage should measure approximately +3.3 V dc. Is the voltage correct? Go to step 2 Replace the system board. See “System board removal”. 2 Measure the voltage on the fuser DC control connector on the LVPS. Measure the voltage on pin 6 of the connector. Does the voltage measure approximately +3.3 V dc? Replace the fuser assembly. See “Fuser assembly removal”. Replace the LVPS assembly. See “LVPS assembly removal”.
Code: 122.04
Description: Fuser cold.
Remedy: 1 Measure the voltage on connector J17-11 on the system board. The voltage should measure approximately +0.13 V dc to +0.64 V dc as the hot roll lamp turns off and on. Is the voltage correct? Go to step 2 Replace the system board. See “System board removal”. 2 Remove the fuser from the printer. Check continuity of the hot roll lamp by measuring between pins 1 and 2 on the AC fuser connector on the fuser assembly. Is there continuity? Go to step 4 Go to step 3 3 Check to make sure the hot roll lamp is installed correctly. Is the hot roll lamp installed correctly? Go to step 4 Install the lamp correctly. If this does not fix the problem, replace the fuser assembly. See “Fuser assembly removal”. 4 Reinstall the fuser assembly. Watch to see if the lamps turn on and off as the lamp heats up. Do the lamps turn on? Go to step 5 Replace the fuser assembly. See “Fuser assembly removal”. 5 Turn the printer on, and allow it to reach a Ready prompt. Note: The printer may not complete POR and may continue to display the error code. Remove the fuser from the printer. Measure the voltage on connector J17-6 on the system board. The voltage should measure approximately 3.3 V dc. Is the voltage correct? Go to step 6 Replace the system board. See “System board removal”. 6 Measure the voltage on the fuser DC control connector on the LVPS. Measure the voltage on pin 6 of the connect. Does the voltage measure approximately +3.3 V dc? Replace the fuser assembly. See “Fuser assembly removal”. Replace the LVPS assembly. See “LVPS assembly removal”.
Code: 122.05, 122.06
Description: 122.05 Fuser does not raise temperature quickly enough or raises temperature too quickly. 122.06 Fuser Error Fuser failed to raise temperature quickly enough or raises temperature too quickly
Remedy: 1 Measure the voltage on connector J17-11 on the system board. The voltage measures approximately 0.13 V dc to 0.64 V dc as the hot roll lamp turns off and on. Is the voltage correct? Replace the fuser assembly. See “Fuser assembly removal”. Go to step 2 2 Remove the fuser from the printer. Check continuity of the hot roll lamp by measuring between pins 1 and 2 on the AC fuser connector on the fuser assembly. Is there continuity?

Do the lamps turn on? Go to step 5 Replace the LVPS assembly. See “LVPS assembly removal”. 5 Turn the printer on, and allow it to reach a Ready prompt. Note: The printer may not complete POR and continues to display the error code. Remove the fuser assembly from the printer. Measure the voltage on connector J17-6 on the system board. The voltage should measure approximately +3.3 V dc. Is the voltage correct? Go to step 6 Replace the system board. See “System board removal”. 6 Measure the voltage on the fuser DC control connector on the LVPS. Measure the voltage on pin 6 of the connector. Does the voltage measure approximately +3.3 V dc? Replace the fuser assembly. See “Fuser assembly removal”. Replace the LVPS assembly. See “LVPS assembly removal”.
Code: 122.07, 122.14, 122.15
Description: Fuser assembly cam position is not found. 122.07 Fuser Error Fuser timeout waiting for home sensor. 122.14 Fuser Error Fuser timeout waiting for motor to stop. 122.15 Fuser Error Fuser timeout waiting for motor to stop.
Remedy: 1 Observe the fuser drive assembly gears rotate during POR. Do the gears rotate? Go to step 2 Go to step 5 2 Do the gears stop and the fuser drive assembly gears make a loud buzzing sound? Replace the FRUs in the order shown: 1. Fuser drive assembly. See “Fuser drive assembly removal”. 2. “Fuser assembly removal”. Go to step 3 3 Check for correct installation of the fuser control cable to J17 on the system board. Make sure the cable is properly connected. Is the cable installed correctly? Go to step 4 Install the cable correctly. 4 Remove the fuser from the printer. Measure the voltage at the DC fuser control connector on the LVPS on pin 2 and 9 on the connector. The voltage should measure approximately +5 V dc. Is the voltage correct? Replace the fuser assembly. See “Fuser assembly removal”. Replace the LVPS assembly. See “LVPS assembly removal”. 5 Check for correct installation of the fuser drive motor cable to connector J15 on the system board. Is the cable installed correctly? Go to step 6 Install the cable correctly. 6 Remove the fuser fan to gain access to the motor cable. Check the correct installation of the fuser drive motor cable to connector J1 on the fuser drive motor board. Is the cable installed correctly? Replace the following FRUs in the order shown: 1. Fuser drive assembly. See “Fuser drive assembly removal”. 2. System board. See “System board removal”. Install the cable correctly.
Code: 122.08
Description: Fuser Error.
Remedy: 1 Replace the fuser assembly. See “Fuser assembly removal”. Does the error remain? Replace the system board. See “System board removal”. Problem resolved
