2.17.7 Shift tray side to side shift mechanism
In the sort/stack mode, the shift tray [A] moves side to
side to stagger and separate sets of copies.
The horizontal position of the shift tray is controlled by
the shift motor (dc motor) [B] and the shift cam (helical
cam) [C]. After one set of the original is copied and
delivered to the shift tray, the shift motor [B] starts
rotating, driving the shift cam through the timing belt.
The pin [D] fixed to the shift tray base plate [E] is
positioned in the groove on the shift cam, creating the
side to side movement required to stagger copies.
When the shift cam rotates 180 degrees (The tray is fully
shifted.), the plate [F] on the shift cam pushes the
actuator [G] of the shift tray half turn sensor [H] and the
shift motor stops. The next set of copies is then
delivered. The motor rotates repeating the same
process and moving the tray back to the previous
position.
2.17.8 Staple unit paper positioning
In the staple mode, copies are vertically and horizontally
aligned in the jogger unit before being stapled.
For horizontal paper alignment, the jogger motor [A]
moves both the front and the rear jogger fences [B] to
align the copies.
For vertical paper alignment, the positioning roller [C]
and the alignment brush roller [D] push the copy against
the stack stopper [E].
After the trailing edge of the copy passes the jogger unit
entrance sensor [F], the positioning roller solenoid [G] is
energized for 280 ms pushing the positioning roller into
contact with the paper. The positioning roller rotates to
push the paper back and align the trailing edge of the
paper against the stack stopper. Both the positioning
roller and the alignment brush roller are driven by the
transport drive motor through the timing belt [H].
2.17.9 Jogger movement
When the Start key is pressed, the copier sends the
paper size information to the finisher. In accordance with
that data, the jogger motor (stepper motor) starts
rotating to position the front and rear jogger fences [A] 8
mm away from the selected paper’s edges. (1)
After the trailing edge of the copy passes the jogger unit
entrance sensor, each jogger fence moves inward 5
mm. They stop 3 mm away from the paper edges. (2)
Just after the positioning roller pushes the copy back,
each jogger fence moves inward 3 mm more so that the
leaf spring [B] on the rear jogger fence pushes the copy
side edge slightly.
After a copy is stacked in the jogger tray, the jogger
fences move back 8 mm from the copy edge for the next
copy.
