Cause Solution

The sensor that detects residual paper jams is set incorrectly or damaged.

Run the manual sensor test to verify which sensor detects the paper. See Manual sensor test 2 (special-mode test) on page 259 for information. Check the sensor lever to make sure it is set correctly. If it is damaged, replace the corresponding pickup assembly. See Pickup assembly (optional paper feeder) on page 226.

The spring of the sensor lever that detects	Run the manual sensor test to verify which sensor detects the paper. See

	Reconnect the following corresponding sensor connectors:
	● Tray 3: Reconnect connectors (J408) and (J13)
	● Tray 4: Reconnect connectors (J406) and (J22)
	● Tray 5: Reconnect connectors (J403) and (J32)
