If it is damaged, replace the following corresponding part: ● Registration sensor (SR8): Replace the registration assembly. ● Fuser output sensor (SR5): Replace the fuser. ● Fuser loop sensor 1 or 2 (SR14 and SR15): Replace the fuser. ● Duplexer re-feed sensor (SR22): Replace the MP tray pickup assembly. The spring of the residual media jam detective Run the sensor test to verify which sensor detects the media. Check the spring sensor lever is unhooked. of the sensor lever to make sure it is set correctly. Poor contact of the residual media jam detective sensor connector. Run the sensor test to verify which sensor detects the media. Reconnect the following corresponding sensor connector: ● Registration sensor (SR8): Connector (J109) on the DC controller PCA ● Fuser output sensor (SR5): Intermediate connector (J95) and connector (J123) on the DC controller PCA ● Fuser loop sensor 1 or 2 (SR14 and SR15): Connector (J139) on the DC controller PCA ● Duplexer re-feed sensor (SR22): Connector (J107) on the DC controller PCA. The residual media jam detective sensor is defective. Run the sensor test to verify which sensor detects the media.
