Abstract
A copy media feed system includes two pair of feed rolls which are horizontally aligned to form nip areas to engage the media. Each feed roll pair comprises one drive roll and one idler roll. For one pair, the drive roll is an elastomer-covered, high friction roll and the idler roll is a hard, roll. For the second pair the drive roll is a hard, high friction roll and the idler roll is an elastomer-covered roll. This arrangement provides accurate control of the media velocity.
