STACK TRAY
B602 48 SM
Stack-Tray Guide Mechanism
The paddle motor [A] moves the timing
belts [B][G], which drive the cam [D]. The
cam pushes up the first lever [C], which
pushes down the second lever [H]. The
second lever lowers the stack-tray guide
[I].
Home Position
The actuator [F] moves with the cam [D].
The actuator interrupts the home position
sensor [E] while the cam does not push
the first lever [C] (in other words, while the
stack-tray guide is in its upper position).
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
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-
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.
