When a media tray is inserted into a printer with the leading edge of the printed page going into the printer first, multiple sheets of media may slide off the media stack (“shingle”) into the paper path if the primary input tray is inserted too aggressively. This may result in double feeds and/or paper jams for the user. Disclosed is a mechanism that is transparent to the user for slow speed tray insertions but provides force feedback to the user indicating tray insertion at too high of speed. If the user inserts the tray below the speed threshold, then the result is a normal tray insertion. If the user inserts the paper tray above the speed threshold, then there is a feedback to the user to slow the tray insertion to an acceptable velocity.
