I recommend you get a digital camera and set it to take a picture of the projected image on the microfilm reader. Use a machine in a dark corner so the available light doesn't interfere. Brace camera on the reader so it doesn,t move as it will be a very slow shutter spead. Do NOT use flash. Once you have the focus and exposure set, you can take a picture as fast as you find the film. Remember to document the picture for which page of the microfilm or you will have a stack of pictures you don't know what they are from.
Cheaper and quicker than copies.
