500-Sheet Feeder Unit (Tray 2)
The optional 500-Sheet Feeder is replaced as a single assembly. When installed,
the optional feeder is designated as Tray 2. Components of the optional 500-Sheet
Feeder appear below.
Feeder
The feeder is driven by the system’s Main Motor through a coupling gear. The
paper separation mechanism uses separation claws installed in the unit and
elasticity of the paper. It ensures that only one sheet of paper is fed in at time. The
Pick Solenoid is controlled by the system through the PF Drive Board mounted in
the feeder.
