Abstract: An apparatus for controlling curl in sheets between two transports includes a curved baffle placed between the two transports. A thin layer of high velocity air is applied to the curved baffle. The high velocity air layer, which will have a tendency to follow the curved baffle (Coanda effect), will divert sheets (Bernoulli effect) towards the curved baffle. By positioning the curved baffle between the two transports and by applying a uniform air stream to it, a lower pressure area will be created. This will flatten the trajectory of the sheets and ensure acquisition by the downstream transport.

Abstract: An apparatus is disclosed. For example, the apparatus includes a paper feed to feed print media a single sheet at a time, a plurality of rotating discs, wherein each one of the plurality of rotating discs comprises an elastomer ring to secure a leading edge of the single sheet against a registration wall and initiate a flipping process, a plurality of fans to generate an air flow, wherein the air flow levitates a trailing edge of the single sheet during completion of the flipping process, and a movable platform to hold a stack of the print media.
