Fuser
Unplug the machine, and disconnect the fuser cable plug from the
LVPS/HVPS board connector at CN102.
Check for continuity across the fuser by checking across the
connector pins.
• If there is continuity, then check the LVPS/HVPS ( p.242
• If there is no continuity, then disconnect the fuser power cable
at both ends and check each conductor for continuity.
Replace cable if necessary.
• If the cable tests good, then replace the fuser.
Reconnect the cables, turn the machine on, and at &12, check for
approxi5Vdc on pin1 and ground on pin 2. If line voltage
is incorrect on pin1, then see “Engine Board Service Check” in
“Troubleshooting” for more information.
Fuser
Disconnect the thermistor cable from J12 on the engine board.
Measure the resistance across the ends of the thermistor cable.
Replace the fuser assembly if the resistance is lower than 1K ohm
or shorted.
• Resistance measures approximately 400K ohms when cool
and 1K ohms hot.
