Description: The fuser has experienced an error. W = fuser error code, X = fuser mode, Y = previous printer sleep state, Z = next printer sleep state
Low fuser temperature and fuser warm-up failure
Remedy: 1. Remove and then reseat the fuser. Make sure there is no residual paper in the fuser. Make sure the device 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 the power source meets product requirements. Make sure this is the only device using the circuit. 3. Replace the fuser. 4. Check the connector (J704) 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 connector (J131) on the DC controller PCA and the connectors (J109 and J110) on the power line between the low-voltage power supply assembly and the fuser.

High fuser temperature
Remedy: 1. Remove and then reseat 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 connector (J131) on the DC controller PCA.

Drive circuit fault
Remedy: 1. 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 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 connector (J21) on the DC controller PCA.

Fuser pressure-release mechanism failure
Remedy: 1. Remove and then reseat the fuser. Make sure 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 (PS9) is properly functioning. If it is not, replace the fuser gear assembly. 4. Use the fuser pressure-release drive test in the component test to verify that the fuser motor (M4) is properly functioning. If it is not, replace the fuser motor. 5. If the error persists, replace the low-voltage power supply. 6. If this product has been previously serviced, check the connector (J181) on the DC controller PCA.
