Pickup/feed/delivery system The pickup/feed/delivery system consists of several types of feed rollers and sensors. The DC controller uses two motors and two solenoids to drive the rollers. Three media-detection sensors detect media as it passes through the product. If media does not reach or pass each sensor within a specified period, the DC controller determines that a jam has occurred and alerts the formatter.
