Jogging and Stapling
When start sensor (BK-Q4) is activated and infeed sensor (BK-Q1) deactivated
back jogger motor (BK-M2) moves the back jogger up to knock the trail edge of
the set. At the same time the side jogger motor (BK-M3) moves the side guides
against the paper plus a few millimeters to over jog the set by about 5mm, depend-
ing on the set stiffness. The side guides then moves outwards to the paper width
plus about one millimetre. The position is set by the paper width that has been en-
tered and found by encoder (BK-Q12) on side jogger motor. At the same time the
stapler motor (BK-M4) cycles, putting staples through the center of the set. When
the staples contact the clinchers a closed circuit is established (BK-Q19/Q20 - see
page 6-21) by current running from stapler head through staple contacting the
clincher. The closed circuit created, indicates that staples are present. If out of
staples the paper will insulate the stapler head from the clincher, which will result
in an open circuit. The open circuit at this time will indicate, out of staples. The sta-
pler motor (BK-M4) will complete its cycle and stop in upper position as the stapler
home position sensor (BK-Q14) activates.
