  • Patent number: 11891259
    Abstract: A hold down finger for a finisher process tray contacts the top sheet of paper on a paper tray to prevent subsequently printed pages from disturbing pages disposed on the paper tray. The hold down finger includes gears that move a portion of the hold down finger that contacts the top sheet of paper from a retracted position to a forward hold down position along a substantially elliptical path. After each sheet is printed and placed on top of other pages in the paper tray, the paper tray lowers and the hold down finger continues along the substantially elliptical path back to the retracted position. A rack gear associated with the paper tray engages a cylindrical gear of the hold down finger to return the hold down finger to the retracted position if the paper tray is forced upwards while the hold down finger is in the forward position.
