Instructions to an eclipse thermal copier machine?

I'll assume you want to use it to make a tattoo stencil.

Remove the onion skin sheet from your transfer paper (you can even tear the yellow sheet off if you want.). Open the top of the machine and slide the transfer paper (paper side up) through the slot at the back of the open lid. Make sure your transfer is straight and carefully close the lid so that the top part of the paper is just sticking out of the machine. Put the paper with the image you want transferred (image facing down towards the machine) into the slot on the top front of the machine. Push copy and you're good to go.
