Homebrew PCBs

The thermometer stabilized at 294F. Too cold? Too Hot?

I checked it 2 places on the input side of the rollers.

It acts as though it has plastic in it. After about the 5 passes, some chunks of coating were pulled from the photo paper. Maybe too hot?? I could not find any of the paper listed in our database by part number. Checked 3 stores. I suspect most of them have been obsoleted to something newer. Time to find something more recent.
