Pickup, feed, and delivery system
The DC controller controls the pickup, feed, and delivery system according to commands from the formatter.
The pickup, feed, and delivery system uses a series of rollers to move the paper through the printer.
The pickup, feed, and delivery system consists of the following three functional blocks. The DC controller
controls each block to pick up, feed and deliver the paper.
●
Pickup-and-feed-block: Controls the movement of the paper from each pickup source to the fuser inlet
●
Fuser-and-delivery-block: Controls the movement of the paper from the fuser to the delivery
destination
●
Duplex block: Controls the movement of the paper from the duplex switchback unit to the duplex re-
pickup unit (M552dn, M553dn, M553x, and M577 only)
