CHAPTER 2 OPERATIONS AND TIMING
4. No-staple detection
he built-in no-staple detector switch (SW4) in the stapler detects absence of staple in the staple
cartridge.
Staples in the staple cartridge are pushed up by the spring and intermediate plate. Staples are
sent toward the stapler end by the staple feeding roller.
While there are staples, the no-staple detection switch (SW4) is pushed by the staples and the
sorter controller detects the presence of staples.
When staples have exhausted (remaining about 40 staples), the no-staple detection switch
(SW4) is opened (normally open) and the sorter controller detects the exhaustion of staples. At the
same time, the sorter controller causes the staple resupply indicator to light up.
After no staple is detected, stapling operation does not take place. However, when no staple is
detected during continuous stapling operation, the operation is continued until it is completed.
