• Display: 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
  High temperature thermistor 2
• Remedy: 1. Reinstall the fuser. Check the connector (J128) between the fuser and the product. If it is damaged, replace the fuser. 2. Reconnect the connector (J62) on the low-voltage power supply PCA. 3. If the error persists, replace the low-voltage power supply.

• Code: 50.12X.YZ
• Display: 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
  Fuser pressure release mechanism failure
• Remedy: 1. Reconnect the fuser connector (J128) and the DC controller PCA connector (J62). 2. Check the fuser pressure release sensor flag. If the flag is damaged or not properly working, replace the fuser. 3. Reconnect the fuser motor connector (J221) and the DC controller PCA connector (J89). 4. Use the Component Test item in the Troubleshooting menu to test the fuser motor. If the motor fails the test, replace the fuser motor. 5. If the error persists replace the fuser.
