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 printer. 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.
