Abstract
A print media sheets trailing edge knockdown stacking assistance system, in a compiler or other stacking system with a substantial sheet gravity drop, activated for each ejected sheet to move substantially linearly and perpendicularly downwardly from above, but adjacent to, the sheet ejection position to engage a sheet end area and rapidly push it down towards the underlying stack of sheets and into engagement with any sheet compiling device, then automatically rapidly reciprocally lifting up out of the way above the sheet ejection position before another sheet is ejected, without any significant pause between its up and down movements.
