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 all-in-one. If media does not reach or pass each sensor within a specified time
period, the dc controller determines that a jam has occurred and alerts the formatter.
