Abstract
An improved media rotator/translator apparatus includes a cylinder on sphere nip. A series of beveled/spur gears are included, one of which rotates co-axially but independent to the drive roll shafts. This enables the drive rolls to be driven about their own axis while simultaneously allowing for rotation about the roll shaft axis. A ball idler is positioned above each drive roll providing media normal force. Thus, sheet translation, jogging, and rotation is obtained, but with no relative motion, thereby eliminating marking of certain media.
