4.5 PRESSURE PLATE UP/DOWN MECHANISM
[O]
[R]
[N]
After the master making process is finished, the master eject motor [A]
turns clockwise to raise the pressure plate [B].
When the master eject motor turns, the gear [C] is driven through the timing
belt [R] the gears [D], [E], [F], [G], [H], [I], [J], [K], [L] and [M]. The pin [N] on
the gear [C] which is inserted into the link [O] rises and lifts the left end of
the link; thus, raising the pressure plate [B].
The gear [C] continues to turn until the lever [P] moves into the notch on
the bottom of the cam, located behind the gear [C]. At this time, the master
eject motor [A] stops as the lower end of the lever [P] pushes the pressure
plate position switch [Q]. Thus, the pressure plate is held in the upper posi-
tion.
When the master eject motor turns clockwise, the gear [I] turns clockwise,
but the upper first eject roller does not turn because of a one-way clutch in
the gear [I]. Also, when the master eject motor turns in the reverse direction
(counterclockwise), the pressure plate does not move because of a one-
way clutch in the gear [L].
NOTE: The VT2100/VT2130/VT2150 use a gear instead of a timing belt
[R]. (See page 2-79.)
