Abstract
An automatic printing machine for producing successive duplex prints forms an image on a first side of successive print substrates, transports successive substrates having images on a first side through the machine to form images on the opposite side of the substrate. The substrate transport path inverts each successive substrate twice about an axis perpendicular to the direction of the path and has a side shifting inverter to invert successive substrates once about an axis parallel to the path direction and includes a first substrate guide with a top sheet insertion baffle and a bottom sheet insertion baffle defining a portion of the substrate transport path, one of the baffles having at least one aperture for a rotatable segmented drive roll having a flat segmented portion and a curved segmented portion, the curved portion extending through the aperture when the drive roll is rotated to be in substrate driving engagement with the remaining baffle, the flat segmented portion of the drive roll not extending through the aperture when adjacent the aperture. The inverter further include a direction reversing arcuate substrate guide to guide a substrate around a direction reversing path about an axis parallel to the path direction and a transport to transport a substrate through the arcuate guide. In a preferred embodiment the inverter portion of the duplex path is in a removable cassette which is interchangeable with a print substrate cassette.
