I have a TL902 Thermal laminator with a brand name Scotch and a question along the line of thought if I may. What is the proper way to determine the temps it runs at as all the manual says is two temps one 3mil  thin stock,second 5mil thicker stock? I have a MASIONE Infrared Thermometer (58 degrees to 716 degrees F). Will that be accurate when dot is ob board as soon as it can be seen coming out of lam? I am trying to figure out toner transfer and green trf transfer temps out for size before I buy a Apache ect.
