<p>A printer (10) for printing images from a photoconductor (28) onto copy sheets (60) and tab stock (71) includes stalled roller registration nip (91,92) in a copy sheet path. The printer has a special materials tray (72) and a sheet feeder (73-75) for feeding tab stock from the tray to the paper path. Dual sensors (81,82) connected to an AND gate (85) are positioned in line across the paper path downstream of the special materials feeder (72) to sense the feeding of tab stock (71) and send a signal to a controller (100) which stops the sheer feed. Once a signal is received by the controller that an image is in a particular position on the photoconductor (28), the sheet feeder is started again by the controller (100) with the roller registration nip (91,92) operating at process speed as well. When standard copy sheets are fed from conventional paper trays, the stalled roller registration nip (91,92) operates to stall and register copy the sheets before they are fed to the U photoconductor. <IMAGE></p> |
