<Jogging Operation>
• Jogging bar moves the papers stacked in interstage stack to reference plate,
and jogs the papers toward STS. The papers are detected by sheet detecting
sensor when they are in the position where stapling is possible.
This procedure ensures stapling of the arranged papers.
Reference plate also ensures discharge into a fixed position.
<Shift Operation>
• Papers jogged to the direction of STS go through shift operation. Therefore,
single paper shifts by the shift bar are sorted when discharged.
(There is no shift operation for the stapled paper.)
<Jogging/Shift Mechanism>
• Jogging and shift operation is carried out by the jogging bar and shift bar
which are moved by pinion, which is driven by the A and B movement of
jogging motor (M2) gear.
• Holding spring pushes rack toward pinion to ensure proper engagement of
the rack and pinion. The jogging bar’s range of movement differs depending
on the size of paper (A4, LTR only).
