If media is jamming at the ITM assembly, there
may be a problem with the ITM CRU assembly.
If a replacement fuser assembly is not available,
remove the fuser and check for pieces of paper
stuck in the fuser, or other signs of
contamination that might cause a paper jam.
CAUTION: The fuser may be hot, use caution
before removing or servicing.
Go to the "Paper Exit Sensor Service Check"
on page 2-67 and check the paper exit sensor
(PHl 1).
• If a problem is found with the fuser and it is
below the maintenance count, repair or
replace the fuser assembly.
• If the fuser is above the maintenance count,
inform the customer that the printer should
have a maintenance kit installed.
If replacing the fuser does not fix the problem,
check all the fuser cables (HTT and MSN) for
correct installation and any signs of damage.
• If incorrect, replace the cable(s).
• If the cables are good, replace the engine
board.
