ABSTRACT:
A method of decreasing wait time for a printed page and an image forming device implementing the method which includes an output transport mechanism configured to provide a higher linear velocity for print media than the linear velocity at which the media is transported through the rest of the image forming device. The rollers or other motion imparting apparatus of the output transport mechanism are driven at a higher linear velocity, but connected to their drive source using a slip drive mechanism. The slip drive mechanism maintains a predetermined tension on the media so that the media cannot be deformed before it has completely exited from the print engine. The overall time needed to deliver a printed image to the user is significantly shortened.
