2.2 PRIMARY MECHANISMS
2.2.1 TRAY SHIFT
As stated above, the shift tray cover [A] moves from left to right to create two
possible positions for the copies to stack up. This motion is driven by the tray motor
[B], which connects to the slip disc [C] via a small shaft. The shaft is connected at
the rotational center of the disc. However, there is an off-centered white square
attached to the top surface of the disc. When the tray cover is attached to the unit,
this square fits into a groove [D] (approximately equal to its width) that runs
lengthwise along the underside of the tray
When the motor is running, the disc rotation causes the off-centered white square
to change position. Since the square only has freedom of movement along the
groove [D], the only net motion of the tray is from left to right.
