This article describes apparatus for providing automatic damped bail closure within one index of platen motion in a high speed printer or the like. Damped bail motion is desirable for reducing marking on the print sheet and for reducing noise. In the figure, platen 2 is provided with a gear hub 4 for platen gear 6. Platen gear 6 is on a common center with platen 2 and hub 4. Springs 8 bias platen gear 6 counterclockwise against gear hub 4. As platen 2 turns clockwise, platen gear hub 4 also turns clockwise and drives platen gear 6 in the same direction. This action engages gear 10 including an integral cam, and drives it counterclockwise. Paper bail roller 12 is mounted at one end of arm 14 which is pivotally mounted to frame 18.
