The system is the combination of an envelope feeder and a laser printer, with some additional control mechanisms. An envelope conveyor system is positioned adjacent to a media input slot on a laser printer and envelopes are fed into a pickup assembly positioned within the media input slot in a controlled manner. By controlling the conveyor speed, a stack of envelopes having a limited and known number of envelopes is accumulated within the pickup assembly such that the pickup roller in the assembly can feed envelopes into the printer at a rate equal to or greater than the speed at which the printer can apply an image to each envelope. A control circuit provides a feedback signal to the conveyor to control conveyor motor actuation. The result is a smaller, less expensive and simpler feed system for an envelope printer.
