HP Say:

50.WX.YZ Fuser error To continue turn off then on

Description

The fuser has experienced an error.

W = fuser error code, X = fuser mode, Y = previous printer sleep state, Z = next printer sleep state

Recommended action

W = 2

Fuser warm up failure

• Reconnect the connector (J128) between the fuser and the DC controller PCA.
• Turn the product off. Remove the fuser and then reinstall it. If the error persist, replace the fuser.
• If the error persists, replace the low-voltage power supply.

W = 3

Low temperature thermistor 1

• Reinstall the fuser. Check the connector (J128) between the fuser and the product. If it is damaged, replace the fuser.
• Reconnect the connector (J82) on the DC controller PCA.
• Replace the fuser.
• W = 2: Reconnect the connector (J62) on the low-voltage power supply PCA.
• If the error persists, replace the low-voltage power supply.

W = 4

High temperature thermistor 1

• Reinstall the fuser. Check the connector (J128) between the fuser and the product. If it is damaged, replace the fuser.
• Reconnect the connector (J82) on the DC controller PCA.
• Replace the fuser.
• If the error persists, replace the low-voltage power supply.

W = 6

Drive circuit fault

• Check the power source. Make sure the power source meets product requirements.

NOTE: If the power source does not meet the power frequency requirement of 40 to 70Hz, the fuser temperature control does not work properly and causes this error.

• Reconnect connectors J51, J52, J53, and J162 and DC controller PCA connectors J85, J95, and J96.
• If the error persists, replace the low-voltage power supply.

W = 10

Low temperature thermistor 2

• Reinstall the fuser. Check the connector (J128) between the fuser and the product. If it is damaged, replace the fuser.
• Reconnect the connector (J62) on the low-voltage power supply PCA.
• If the error persists, replace the low-voltage power supply.

W = 11

High temperature thermistor 2

• Reinstall the fuser. Check the connector (J128) between the fuser and the product. If it is damaged, replace the fuser.
• Reconnect the connector (J62) on the low-voltage power supply PCA.
• If the error persists, replace the low-voltage power supply.

W = 12

Fuser pressure release mechanism failure

• Reconnect the fuser connector (J128) and the DC controller PCA connector (J62).
• Check the fuser pressure release sensor flag. If the flag is damaged or not properly working, replace the fuser.
• Reconnect the fuser motor connector (J221) and the DC controller PCA connector (J89).
• Use the Component Test item in the Troubleshooting menu to test the fuser motor. If the motor fails the test, replace the fuser motor.
• If the error persists replace the fuser.
