Setting Up the Scanner
Follow these steps to set up the scanner:
1. Take the scanner out of its box and place it on a flat, stable
surface with the rear panel facing you.
2. Remove the tape securing the scanner cover and pull out
the paper underneath the cover.
3. Locate the round knob in the middle of the rear panel.
4. Turn the knob counterclockwise. If necessary, use a coin to
loosen it. The knob has a built-in spring, so it pops out a
little when it is released. You cannot remove the knob.
