Table 3-25Causes and solutions for residual media jams

Cause Solution

Poor contact of the loop-sensor connector and loop sensor 1 and 2.

Reconnect the connectors of the loop 1 sensor (1 and 2):

●Loop 1 (J11, J352, J350, J50) and the DC controller (J139)

●Loop 2 (J10, J352, J350, J50) and the DC controller (J139)

The loop sensor is defective.

Run the manual sensor test. See Manual sensor test (special-mode test) on page 246 for information. If the sensor is defective, replace fuser. See Fuser on page 85.

The fuser-delivery sensor is defective.	Run the manual sensor test to make sure the fuser-delivery sensor is
	functioning properly. See Manual sensor test (special-mode test)
	on page 246 for information. If the sensor is defective, replace the fuser. See
