Fuser Cover Assembly
(Assembly includes
Thermistor and Thermal
Fuses.)
Check for damage to the thermistor
assembly. If damage is found,
replace the fuser top cover
assembly. If no damage is found,
check the resistance of the
thermistor between pins J6-1 and
J6-2 on the cable.
• HOT = 2.5K ohms
• COLD =150K ohms to 260K ohms
If the resistance is incorrect, replace
the fuser top cover assembly. If the
resistance is correct, check each pin
of J6 to ground. If there is continuity,
replace the fuser cover assembly

Fuser Control Board
Check for continuity between J6-1
and J1-2 and between J6-2 and
J1-3. If incorrect, replace the fuser
control board. If correct, go to step 3.
