I tested it very minimally by plugging it in and turning some of the knobs. It made some marks on the paper but I couldn't figure out how to get the paper to feed automatically.
I did not connect the lead splitter cable when testing. Please understand that we are not medical professionals and have not tested this vintage device for safety or effectiveness.
