Abstract: An paddle apparatus for a finisher includes a rotatable shaft and a paddle coupled to the rotatable shaft. The paddle is rotatable in a forward direction to compile a recording medium toward an end of a register tray of the finisher, and is rotatable in a reverse direction to apply a downward force to the compiled recording medium. An amount that the paddle is rotated in the reverse direction can be varied based on a height of the compiled recording medium in the register tray.
