Ricoh A156 - Stapler

9. STAPLER
In automatic or manual stapling mode, the stapler motor [A] rotates when the
grip motor stops rotating after the grippers bring the stacked copies to the
stapling position.
The staple gear [B] rotates counterclockwise, and the pin on the gear rotates
the staple arm [C] counterclockwise, then clockwise. The ratchet [D] lowers
and rises to rotate the ratchet wheel [E] counterclockwise. Then the staple
feed rollers [F] turn via gears to feed a staple sheet to the hammer.
While both the front and rear staple arms rotate counterclockwise, the
hammer [G] lowers. At the same time, the staple cam plate [H] lifts the
clincher [I]. The hammer and the clincher staple the copies. Then, while the
staple arms rotate clockwise, the hammer rises and the clincher lowers.
When the staple home position switch (a normally-closed type) [J] is
deactivated, the stapler motor stops.
