• Code: 50.9
• Display: 50.WX.YZ Fuser error To continue
• 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 fuser temperature 2
• Remedy: 1. Remove and then reseat the fuser. 2. Check the paper type setting using the product menus and in the printer driver. Making sure that they match and are correct for the type of media being used. 3. Replace the fuser. 4. If this product has been previously serviced, check the connector (J131) on the DC controller PCA.

  Low fuser temperature 3
• 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 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.
