Abstract
A modular duplex media handling system is used in conjunction with a simplex media handling print recording apparatus. The duplex media handling system is linked by a transmission to a print recording system drive motor. The drive motor drives feed rollers and metering rollers or the simplex media handling system. The transmission is media-activated to allow the duplex handling drive rollers to be disengaged, engaged for rotation in the same direction as the feed rollers, or engaged for rotation in the opposite direction as the feed rollers.
