Theory of Operation
550-Sheet Feeder Assemblies
The 550-Sheet Feeder forms a base for the printer and adds a 550-sheet,
universal tray. Control signals reach the sheet feeder by a single connection.
The sheet feeder is secured to the print engine with four screws located under
Tray 2.
Major functional components of the optional 1100-Sheet Feeder are
described below.
■ No Paper Sensor
Detects presence or absence of print media in the tray based on the
position of the Actuator.
■ Feed Rollers
When the Feed Solenoid energizes, the Spring Feed force engages the
Gear Feed and the Gear Idler Feed to turn and feed the paper from the
paper tray. This activates the Paper Pick Assembly. After completion of
one turn, determined by a cutout in the Gear Feed, the Gear Feed and the
Gear Idler Feed are disengaged stopping the paper Retard Roller. This
allows one sheet to be fed at a time.
■ Turn Clutch
Transfers the drive energy from the main drive assembly to the roll turn
assembly.
■ Paper Size Switch
Detects print media size and installation of the paper tray.
■ Feed Solenoid
Controls the operation (rotation/stop) of the Feed Roller Assembly by
controlling the rotations of the Gear Feed.
■ Turn Roller
The Turn Roller receives drive energy from the Drive Assembly through
the Turn Clutch and transports the print media out of the paper tray to the
printer’s Registration Rollers.
Note
The Phaser 6300/6350/6360 supports the installation of only one 550-
Sheet Feeder. However, an 1100-Sheet Feeder is available to increase
the tray count to the maximum of five.
