Yesssss yes....
thermistor is where I started with all this...

we landed on the diode discussion because the PACE PP330 circuit
can be hacked by for higher toner melt temps by changing out two resisters

Why not just use a thermistor? It's made for that purpose, already calibrated, costs a dollar or so, is tiny snd rugged, and can be read with a simple ohmmeter.

Wow
all sorts of web sources explaining how to measure temp with diodes and transistors.

A transistor with two of three legs soldered together makes a temperature probe. Is
the temperature inside of lam too hot? Google for temperature probe circuits like I
do for other projects.
