STACK TRAY

Stack-Tray Guide Mechanism

[D] [E]
The paddle motor [A] moves the timing
[C]
belts [B][G], which drive the cam [D]. The
[B]
cam pushes up the first lever [C], which
[A]
pushes down the second lever [H]. The
second lever lowers the stack-tray guide
[I].
[F]

Home Position

The actuator [F] moves with the cam [D].
[G]
The actuator interrupts the home position
sensor [E] while the cam does not push
[K]
the first lever [C] (in other words, while the
stack-tray guide is in its upper position).
[J]
[H]

Stapler Switch

The second lever [H] moves with the
stapler-switch actuator [J]. When the first
lever pushes the second lever (in other
words, when the stack tray guide is in its
lower position), the actuator pushes the
[I]
stapler switch [K], turning it on. The stapler
can operate only when this switch is on.

Safety Feature

The stapler switch, along with the stack-
B602D949.WMF
tray guide mechanism, works as a safety
feature. The stapler operates only when the stack-tray guide is in the lower position.
When the stack-tray guide is in this position, the user cannot access the stapler
through the opening between the stack-tray guide and the stack tray. Therefore,
staples do not injure the user.
