Zusammenfassung:	A high accuracy pen plotter includes an automatic sheet feeder for feeding individual sheets of paper from a paper tray to a platen for plotting. A microprocessor, various stepper motors and encoders allow for accurate and repeatable positioning and alignment of the sheet of paper to be plotted. The sheet of paper is automatically fed from the tray to the platen, is pulled entirely free from the tray, is aligned against a reference edge and may be forcefully ejected from the plotter after plotting is finished.
