Staple sheet empty detection

• The Staple Empty Detecting Sensor is used to detect whether there is a staple sheet or
not in the Staple Cartridge.
• When there are about 20 staples left in the Staple Cartridge, a staple sheet empty condi-
tion results and a staple-empty display is given on the control panel of the main unit.
• If a staple sheet empty condition is detected during a stapling sequence, that particular
sequence is continued until it is completed. A staple empty display is then given.
• After a new Staple Cartridge has been loaded, the Stapling Motor is energized until the
Self-Priming Sensor detects loaded staples (L), thereby feeding the staple sheet to the
stapling position.
