Disclosed is an ultra thin page-edge gripper designed for use where thickness requirements are critical. For Thermal Ink Jet (TU) there is a desire to hold a page that is to be printed f d y against a given location on a platen. Where vacuum and electrostatic hold-downs are not appropriate, simple mechanical gripping of the page edges can be advantageous. If the various pages to be gripped are of different lengths, the gripping means must be constructed to allow repositioning on the platen. However, since the print heads must travel over the gripper during the printing operation, and the print head to printing media gap must be small, the gripping mechanism must be exceedingly thin. In addition, the gripping force must be substantial and uniform over the length of the gripper. These requirements are nearly impossible to achieve through the use of normal mechanical grippers.
