black thumbwheel. Wet some cotton swabs or cotton cloth with cleaning solution. While rotating the upper
platen roller with your fingers, clean the entire roller using one or more cotton swabs. Wipe any dirt or
accumulated adhesive off the upper platen roller.

Locate the feed roller. It is the smaller, black rubber roller on the underside of the top cover, toward the
rear of the printer. While rotating the roller with your fingers, clean the entire roller using one or more
swabs.
