I would assume this is not so, the printer is probably fixed at a certain temperature and using other toner would cause problems.
(I may be entirely wrong)
I would look into finding out the correct temperature and increasing the laminator temperature.
Just make sure the laminator can withstand it, especially if you need to go over 170 degrees, at that temperature the plastic case warps on the top of mine.
I notice a few people have changed the end-mounts which hold the rollers\motor as the standard plastic ones on some laminators seem to fail under the higher temperatures.
