<p>Printers and copiers have paper handling mechanisms that incorporate form feeding tractors (20, 100) to move a continuous form or web (12, 22) having edge holes (402, 452, 458). It has been found that the web can be driven at a high acceleration yet uses a small number of pins (28, 112, 304, 305, 328, 330, 350, 352, 400, 450, 456, 460, 462, 464, 466) by setting the pin pitch of the tractor being greater than the pitch of the edge holes (402, 452, 458).</p> |
