Board
The operation of the fuser solenoid
can be observed by removing the
redrive assembly. Check for proper
mechanical operation of the solenoid
and associated hardware, link and so
on. If correct, disconnect the DC fuser
cablefromJ1onthefusercontrol
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.
