What should the resistance of the fixing heater be? This one measures about
34 ohms.
Chris
34 ohms.

Thanks. The top and bottom lights come on when the button is pushed. I
also watched the voltage to the heater. It's only on for a second or
so but it looks to be around 100V. If the heater is good and getting
power, is the temp sensor at fault?
Chris
I found a fuser from a Canon CFX-L3500 fax and it works. I think the
part numbers are different but are the specs similar?
Chris
Yes, it's very well possible that the sensor is defective.
Top and bottom lights means a fuser error. We already know that the
heater is OK, so remove the thermistor (temperature feedback)
connector and measure the resistance between pins 1 and 2. Normal
resistance is 440K ohms
+/- 30K at 20 degrees C.
I dunno. I don't have the specs for that fax. But you could measure the
resistance of the heater and the thermistor and check if those are within
the specs of your HP.
