The paper pushing plate pushes in the center of the paper stack to feed it toward the paper
fold rollers. Then, the paper fold rollers and bind delivery rollers deliver the paper stack to
the bind tray.

5.3 Paper Feed System

5.3.1 Outline
The paper feed system feeds a stack of sheets (coming from the finisher) to the position
where the center of the paper stack (stitching position) is aligned to the stapler's staple, al-
lowing the next step (stitching and folding) to be performed.
lowing the next step (stitching and folding) to be performed.
When sheets of paper have been stacked and aligned on the processing tray, the paddle
motor (M2) rotates in the reverse direction, causing the swing guide to descend. As the
swing guide descends, the paper stack is sandwiched between the upper and lower stack de-
livery rollers. The delivery motor (M3) rotates in the reverse direction, feeding the paper
stack toward the saddle unit. When the leading edge of the paper stack reaches the folding
position sensor (PI10), the finisher controller PCB drives the delivery motor a specified
number of motor pulses to stop the center of the paper stack (stitching position) at the
stapler's staple position. Before the paper stack passes through the stack feed rollers, the
feed motor (M1) is driven to rotate the stack feed roller (lower) so that the leading edge of
the paper stack is not bent.

When stitching is complete, the feed motor (M1) rotates, causing the stack feed roller (up-
per) to descend. The paper stack is sandwiched between the stack feed rollers. Then, the
bind clutch (CL1) is turned ON to rotate the feed motor (M1) in the forward direction, thus
feeding the paper stack to the folding position. The feed amount is equivalent to the number
of pulses used to drive the feed motor (M1) until the paper stack reaches the folding posi-
tion.

5.5 Fold/Delivery System
5.5.1 Outline
The paper fold mechanism consists of a guide plate, paper fold rollers, and a paper push-
ing plate.
The guide plate, paper fold rollers, and paper pushing plate are driven by the staple/fold
motor (M7). The drive force is transferred with a combination of gears and cams. Motor
operation is monitored by the staple/fold motor lock sensor (PI14).
operation is monitored by the staple/fold motor lock sensor (PI14).
Until the paper stack reaches the folding position, the guide plate covers the paper fold
rollers to act as a paper path through which a paper stack is fed to the saddle unit and to pre-
vent a paper stack from touching the rollers.
vent a paper stack from touching the rollers.
A folding home position sensor (PI11) is provided to detect the positions of the paper fold
rollers and paper pushing plate.
The paper stack folded in two by the paper fold rollers is delivered by bind delivery roll-
ers.
The bind delivery rollers are also driven by the staple/fold motor (M7).
A bind tray sensor (PI13) is provided on the bind tray to detect presence/absence of a pa-
A bind tray sensor (PI13) is provided on the bind tray to detect presence/absence of a pa-
per stack; however, it is not used to detect a jam.
