9. Stapler (FS-517/518)
B. Staple control
(1) Stapling
• After completing the alignment operation of the alignment plate, the stapler motors /Rr
and /Fr perform the stapling operation.
• The stapling operation is completed when the stapler motor home sensors /Rr and /Fr in
the staplers /Rr and /Fr detect the home position and turn ON.
(2) Nip operation of stapler (FS-518 only)
4
• When 60 or more sheets of paper are stapled, the staplers/Rr and /Fr perform the nip
operation to prevent paper bending. With 60 to 89 sheets, it is performed for every 5
sheets and with 90 to 100 sheets, it is performed for every single sheet.
(3) Clogged staple detection
• During the stapling operation, it is determined that the staple has been clogged and the
stapler motors /Rr and /Fr turn OFF if the stapler motor home sensors /Rr and /Fr do not
turn ON after a specified period of time since they turn OFF.
(4) Cartridge detection
• The cartridge set switches /Rr and /Fr detect the presence of a cartridge or the incorrect
setting of a cartridge.
• When no cartridge is set or it is set incorrectly, the main body displays the error message
on its display panel.
(5) Staple detection control
• When the staples run out, the staple empty switches /Rr and /Fr turn ON and the main
body displays the error message on its display panel.
