My laser is Laser 1 on 2, don't remember. I took it apart and it take
some searching for th heater element leads, but it my case it runs
from left to right, inside theheating drum. All other leads are for
temp regulation. I was curious to see if the fuser heats up and
decided to apply a 26V AC just because that was the transformer I had
at the time. I touche a thermometer probe to thedrum and connected
the 26V- the temp slowly, very slowly started to ramp up. That was
encouraging to me, it proved the fuser was operational. For some
eason the resistance I got was exceptionally low, 4 ohms or so.
My next question si: can I use a regular dimemr to adjust the
temperature?
