Code: 50.2X.YZ
Display: 50.2X.YZ Fuser Error
Description: The product experienced a fuser error. • X = fuser mode • Y = previous printer sleep state • Z = next printer sleep state
Low fuser temperature and fuser warm-up failure
Remedy: 1. Remove the fuser, and then reinstall the fuser. Make sure that there is no residual paper in the fuser. Make sure that the product is not located in front of a vent or window where cool air may interfere with the ability of the fuser to heat up. 2. Check the product power source. Make sure that the power source meets product requirements. Make sure that this is the only device using the circuit. 3. Replace the fuser. 4. Check the connector (J50) between the fuser and the printer. If it is damaged, replace the fuser drive assembly or fuser. 5. If the error persists, replace the low-voltage power supply. 6. If this product has been previously serviced, check the connectors (J160 and J162) on the DC controller PCA and the connector (J25) on the power line between the low-voltage power supply assembly and the fuser.

Code: 50.3X.YZ
Display: 50.3X.YZ Fuser Error
Description: The product experienced a fuser error. • X = fuser mode • Y = previous printer sleep state • Z = next printer sleep state
High fuser temperature
Remedy: 1. Remove the fuser, and then reinstall the fuser. 2. Check the paper type setting using the product menus and in the printer driver. Make sure that they match and are correct for the type of media being used. 3. Replace the fuser. 4. If the error persists, replace the low-voltage power supply. 5. If this product has been previously serviced, check the connectors (J160 and J162) on the DC controller PCA.

Code: 50.4X.YZ
Display: 50.4X.YZ Fuser Error
Description: The product experienced a fuser error. • X = fuser mode • Y = previous printer sleep state • Z = next printer sleep state
Drive circuit fault
Remedy: 1. Check the power source. Make sure that the power source meets product requirements. NOTE: If the power source does not meet the power frequency requirement of 43 to 67Hz, the fuser temperature control does not work properly and causes this error. 2. If the error persists, replace the low-voltage power supply. 3. If this product has been previously serviced, check the connectors (J160 and J162) on the DC controller PCA.

Code: 50.4X.YZ
Display: 50.4X.YZ Fuser Error
Description: The product experienced a fuser error. • X = fuser mode • Y = previous printer sleep state • Z = next printer sleep state
Remedy: 1. Check the power source. Make sure that the power source meets product requirements. 2. Reconnect the connector (J150) on the DC controller PCA. 3. If the error persists, replace the low-voltage power supply.

Code: 50.7X.YZ
Display: 50.7X.YZ Fuser Error
Description: The product experienced a fuser error. • X = fuser mode • Y = previous printer sleep state • Z = next printer sleep state
Fuser pressure-release mechanism failure
Remedy: 1. Remove the fuser, and then reinstall the fuser. Make sure that there is no residual paper in the fuser. 2. Check the fuser pressure-release sensor flag. If it is damaged, replace the fuser. 3. Use the sensor test in the manual sensor test to verify that the fuser pressure-release sensor (SR7) is properly functioning. If it is not, replace the sensor. 4. Use the fuser pressure-release drive test in the component test to verify that the fuser motor (M2) is properly functioning. If it is not, replace the fuser motor. 5. If this product has been previously serviced, check the connector (J128) on the DC controller PCA.

Code: 50.8X.YZ
Display: 50.8X.YZ Fuser Error
Description: The product experienced a fuser error. • X = fuser mode • Y = previous printer sleep state • Z = next printer sleep state
Low fuser temperature 2
Remedy: 1. Remove the fuser, and then reinstall the fuser. Make sure that there is no residual paper in the fuser. Make sure that the product is not located in front of a vent or window where cool air may interfere with the ability of the fuser to heat up. 2. Check the product power source. Make sure that the power source meets product requirements. Make sure that this is the only device using the circuit. 3. Replace the fuser. 4. If the error persists, replace the low-voltage power supply. 5. Check the connector (J50) between the fuser and the product. If it is damaged, replace the fuser drive assembly or fuser. 6. If this product has been previously serviced, check the connectors (J160 and J162) on the DC controller PCA and the connectors (J25) on the power line between the low-voltage power supply assembly and the fuser.
