Abstract

A speed mode for a printer (1) which has a pivotally mounted autocompensating system (19) mounted at an intermediate position in paper guide (17). That system (19) is driven by a motor (40) through a slip drive (70, 72, 74). The motor also drives paper feed system (15). When the motor turns in a direction to feed by system (15), the intermediate system is moved away from the paper guide. In basic operation, when a sheet (5) reaches a position to be fed by the intermediate system, the motor is reversed, and the intermediate system pivots against the paper for moving it further through the paper guide. In the speed mode the intermediate system is not employed and all of the feed is by the system at the tray. Since this will not feed shorter sheets, preferably the speed mode must be positively invoked, as by operator input or definitive information in the header of a print job.
