With the customer's permission, if available, try a new ITM or fuser. FRU 1 ITM Assembly 2 Fuser Assembly Exit Sensor (PHI 1) HTT Cable MSN Cable Engine Board Action 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. 2-70 Service Manual
