I have a digital thermomoeter that would fit into the exit just fine. The laminator would probably grab the thermometer if I inserted it on the input side.
I should take this thing apart just to see how it's built. But right now it's so nice to have such consistantcy. Funny thing, the heat and pressure from the two rollers is very high. I've never had my magazine paper wrinkle before. The paper looks like it shrinks as it enters the laminator. If I'm right, it sure is a great problem to have. There is an external temperature dial that deals with that nicely.
They H310 must be obsoleted or something to get a price like that. Plus I got the shipping for zero dollars.
This whole board making project was suppose to be in addition to my other projects, not in place of them! LOL!
I'll get some HP photo paper today.

I was told it was not spring loaded - and it's not per se, but a spring at the ends do hold pressure and will allow the rollers to open a tad with the thicker boards. Using a .062" PCB I bevel the edges a bit and it will usually feed in, sometimes I have to push a bit to get the board started, but after starting it feeds just fine.

Both worked better than acetone since they did not evaporate to fast and stain the copper. The edges of the board are stained, but are also super rough from being sheared. I should try both solvents on a board with no copper.
