Turn on the microfiche reader. There is usually a button on the left side of the machine. It will take a couple seconds for the machine to start.
Pull the tray out from under the lens. A glass panel will rise.
Place the microfiche under the glass panel. The microfiche should be label side up.
Push the tray back in. The glass panel will lock into place and text will appear on the screen.
Position the tray so that the first frame is displayed.
Pull the tray out slowly counting the frames as they pass by the screen. Write down the total.
Position the tray so that the first frame is visible again.
Move the tray sideways counting the frames as they pass by the screen.
Multiply the two numbers together. This is the total number of frames on the microfiche.
