Abstract
The invention is a method whereby the throughput of a printer is varied according to the length of the media piece (e.g., cut-sheet or envelope) that is being fed into the printer feed path. The media piece moves into the feed path by use of a set of take-up rollers and is directed toward a sensor; the sensor detects the piece's leading edge and becomes activated. The activated sensor in turn activates additional feed roller sets which move the media piece along the feed path. Additionally, the sensor detects the trailing edge of the media piece and asks the printer if another image is to be printed. If another image is to be printed, then the take-up rollers are activated and begin feeding the next piece of media. If another image is not to be printed, then the sensor is deactivated. The feed rollers move the media piece along the printer's feed path and toward a second sensor which detects the leading edge of the media piece and is activated. Once activated, the sensor activates a set of exit rollers which are used for exiting the media piece from the printer. When the activated sensor detects the trailing edge of the media piece, the sensor is deactivated.
