The sensor is mounted on a spring loaded arm, and rides directly on the lower front roller. It looks like a glass bead diode. The arm mount is bolted to the bottom frame via a slot. I just slid the arm out in the slot until it was about 1/4" away from the roller.
Since the actual temperature isn't important, I just moved it out until i got good transfers. The temperature still reads, but is the temperature 1/4" away from the roller, not the roller temperature.
This is the fourth laminator I have modified for toner transfer. This one has outlasted all the others combined. This one was also the simplest mod.

Also the temperature can be raised by simply moving the sensor about 1/4" from the rollers. The roller pressure can also be lowered with 4 screws from the bottom. Note that I replaced the 10 rpm AC motor with a 12 VDC 2 rpm gear motor. I get good transfers with 3 passes.
