For toner transfer, I still use 8 passes (rotate the pcb 90 degrees with
each pass).  I suspect you need to bring the pcb itself up to
temperature also.  For UV film I have to lower the temp to 240 but I can
do it in one pass.

No, the motor is a fixed speed motor.

No, once it's stuck, it's stuck.

I suspect a multi-pass setup would want the TT paper to be smaller than
the pcb, though, so that the laminator grabs the big heavy part before
the light flimsy part ;-)
