My GBC 330 laminator has an analogue controller with a temperature
adjust pot on the back. The max temp was a bit low for toner transfer,
so I checked inside, and sure enough, there was a trimmer to adjust
the max temperature..

I just took the cover off and twiddled the trimmer and it now does
toner transfer, film, and anything else needed.

I can't imagine any other laminator working better.

OK so yours is probably different, but check inside first to see what
is controlling the temp.
