OVERVIEW 13th January 1995

3. OVERVIEW

[A]

This paper feed unit is a two-tray type . Ea ch pape r tray [A] is a drawer type
that can hold up to 250 sheets of paper.

The paper feed mechanism uses a corner separator system. The funct ion of
the system is exactly the same as for the ma in mach ine excep t that there is
no paper size detection. The pape r size for e ach paper tray is input at the
operation panel, either by the technician or by the user.

All the electrical components of the paper tray are controlled by the copier
main board through the tray interface board.

[A]

(A553)

Paper Tray Unit

All the tray rollers are driven by the main motor [A] via timing belt s, clut che s
and a train of gears.

The main motor and the relay clutch [B ] are ene rgize d at the same time as
the Start key is pressed.

The paper feed clutch [C] is energized 300 ms after the main motor starts to
rotate. When th e pa pe r fee d clut ch for the selected paper tray is energized,
paper is fed from the paper tray to the main frame through the relay rollers.
