Duplex check printer having a separately driven document inverting loop

摘要

A duplex check printer includes an upper document path, a print head at one side of the upper document path, and a lower document path having a loop to invert a check so that information can be printed on both sides of the check. The check is driven within the upper document path by feed rolls, which are reversed when the check is driven from the upper document path to the lower document path. The check is driven within the lower document path by belts, which are in turn driven by a separate motor.
