Abstract
An endorser assembly comprising inking, ink transfer and endorser rolls resiliently mounted within a modular type supporting frame to enable removal and replacement of the entire endorser assembly from paper handling apparatus. The endorser and ink rolls are adapted to be easily removed from and replaced in the supporting frame. The endorser roll is adapted to print variable and semi-permanent graphic data on sheets processed by the document count handling device and may be selectively moved between an engaged and disengaged position without being removed from the proper handling apparatus. The data-bearing surfaces are resilient and raised relative to the endorser roll surface. A backing platen cooperative with the endorser roll is provided with grooves aligned with the data-bearing surfaces to prevent "back printing" of the processed sheets being endorsed. The variable and/or semi-permanent data-bearing surfaces are "crowned" in the axial direction of the endorser drum to enable wider "stripes" of graphic data to be printed on the documents being processed. "Long" lines of print may be printed on long documents by using at least one additional roller and an elongated closed loop …
