4.6 JOGGER UNIT PAPER POSITIONING MECHANISM
In staple mode, each sheet of copy paper is vertically and horizontally aligned
when it arrives in the stapler tray.
Vertical Paper Alignment
After the trailing edge of the paper passes the stapler tray entrance sensor [A], the
positioning roller solenoid [B] is energized for a specified time to push the
positioning roller [C] 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 [D].
Horizontal Paper Alignment
When the start key is pressed, the jogger motor [E] turns on and the jogger fences
[F] move to the waiting position, which is 8 mm wider on both sides than the
selected paper.
When the trailing edge of the paper passes the stapler tray entrance sensor, the
jogger motor turns on to move the jogger fences 5 mm towards the paper. After a
short time, the jogger motor turns on again for the horizontal paper alignment then
returns to the waiting position.
