Note: Check the fuser envelope conditioner solenoid adjustment as described in the adjustment section "Fuser Solenoid Adjustment" on page 4-3. FRU Action 1 Engine Board Jumpers Check to make sure a jumper is installed between JP1-1 and JP1-2 and also between JP2-1 and JP2-2 on the engine board. 2 Fuser Envelope Conditioner The operation of the fuser solenoid Solenoid Fuser Control can be observed by removing the Board redrive assembly. Check for proper mechanical operation of the solenoid and associated hardware, link and so on. If correct, disconnect the DC fuser cable from J1 on the fuser control board and check the resistance of the solenoid between J1-2 and J1-4 on connector J1. The resistance measures between 5 ohms and 10 ohms. If incorrect, disconnect the solenoid from J4 and check the resistance of the solenoid between J4-1 and J4-2. If incorrect, replace the solenoid assembly. If correct, replace the fuser control board. 3 Fuser Cable Check the continuity of the fuser cable. If the cable does not measure continuity, replace the cable. Diagnostic Information 2-56
