Abstract
A varible data imprinting machine having an elongated flat printing bed section providing a document supporting surface and having a print wheel pack formed of closely adjacent peripherally notched print wheels, an imprinting carriage moveable through advance and return strokes longitudinally along the document support surface and an elongated rack section perpendicular to the printing bed section subadjacent the wheel pack having a number-indicating rack control panel projecting therefrom and including a plurality of toothed racks coarse manually adjusted longitudinally in the rack case to rotatably index the print wheels to number-printing positions. The rack case includes a pivoted centering blade activated by carriage movement to fine adjust the racks as the carriage leaves parked position and interlock means provided to latch the carriage at parked position following an imprinting cycle until one of the racks is readjusted.
