Outline
The paper is fed off the top of the stack in the speciality tray.
The paper guide holds the paper against the pick-up roller. The pick-up roller
is driven by the motor M1 and the clutch CL2.
The interaction of the pick-up roller and the separation pad ensure that only
one sheet of paper is carried to the registration roller. This procedure occurs for
each sheet.
