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.

Fuser pressure-release mechanism failure

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.
