Pickup-and-feed-system
The pickup-and-feed system consists of two pickup sources (tray 2, which is the cassette, and tray 1,
the multipurpose tray) and two delivery destinations (face-down top bin and face-up rear bin).
The multipurpose paper sensor (SR3) detects paper in the multipurpose tray, and the cassette paper
sensor (SR2) detects media in tray 2.
The DC controller controls the main motor, fuser motor, cassette pick-up solenoid, and multipurpose
pickup solenoid.
The four sensors (top-of-page sensor, paper-loop sensor, fuser-delivery sensor, and bin paper-full
sensor) on the paper-transport path detect the arrival and passage of media. If the media does not reach
or pass each sensor within a specified period of time, the DC controller determines that a jam has
occurred and alerts the formatter.
