It is easy to figure out, pull the fuser unit, attach some slow drive
motor of your choice, attach a thermostat, preferrably electronic not
electromechanic, and you are all set.
There is a thermistor already in place on all fuser units i have ever
seen, they have already figured out how to keep it in contact with the
rotating roller for you. In can be used as an input for a thermostat,
mine is just a plain npn transistor, a pot, a transformer and a solid
state relay i had sitting around. Might not be terribly accurate or
pretty (i hid it in a junction box) but more than enough to do what is
required.
