Tray 2 cassette multiple-feed prevention
The product uses a separation roller method to prevent multiple sheets of print media from entering the
paper path. The Tray 2 cassette separation roller does not have its own driving force. Therefore the Tray 2
cassette separation roller follows the rotation of the Tray 2 cassette pickup roller.
During normal feed, when the product picks up one piece of paper, the Tray 2 cassette separation roller is
driven by the Tray 2 cassette pickup roller through one sheet of paper. Thus the separation roller rotates in
the paper feed direction.
During multiple-feed, when the product picks up more than one piece of paper, the low friction force between
the sheets weakens the driving force from the Tray 2 cassette pickup roller. In addition, some braking force is
