Hi,
Long ago (20-plus years), when I worked in aerospace, we had little
paper strips that we attached inside a unit to find out how hot it got
during test. As I recall, they had dots which permanently changed color
at different temperatures. Google couldn't find them but maybe I didn't
ask it the right question. Has anyone else heard of these? Are they
still made? It seems they would be perfect for measuring roller
temperature.

Try opening it up and looking at the part numbers. The roller temp
isn't always the same temp as the cutoff unless you can measure it
∗between∗ the rollers.
