The machine jams at the fuser when making three or more double sided copies. The third copy will start to exit the fuser, switchback as normal for the second

side and switch again back to the exit causing the sheets to come together and jam.

Solution

CAUSE: The duplex clutches are malfunctioning.

SOLUTION: Replace the two duplex drive clutches (p/n 9322 1500 12).
