An automated media sheet processing system for automated collating, stacking and transferring media sheets exiting a media source includes a dynamically oriented baffle having a plurality of stepped bins. Each stepped bin is slidingly arranged adjacent another stepped bin, with the stepped bins configured to receive media sheets and allow them to fall onto and accumulate on the stepped bins. The stepped bins may move and change orientation into a stair configuration descending in different directions. An automated reciprocating pusher may move in the different directions orthogonally to the stepped bins to move and collate the media sheets into collated stacks downstream the stepped bins on different or opposite sides of the dynamically oriented baffle, with no reset or extraneous movement needed between reciprocating pushes. No reset is needed because the reciprocating pusher ends a first push in position to start a next push to the opposite side.

This disclosure is directed to a scanning device having a which has a tray set, a movable scanning module and an automatic document feeder. The tray set has a feeding tray and a first output tray. The movable scanning module is movable between a first position and a second position. The automatic document feeder has a flip path, a feeding path, an output path, a returnable path and a feeding wheel group. The feeding path is disposed corresponding to the first position and connecting with the feeding tray and the flip path. The output path is disposed corresponding to the second position and connecting with the first output tray. The returnable path has an intersection connecting with the flip path and the output path. The movable scanning module scans two sides of the sheet at the first position and the second position respectively.
