4. Master Eject Clamper Mechanism
/
[cl
[G]
When the drum has turned 230 degrees past the second drum position sensor activation
position, the master eject clamper solenoid [A] turns on and turns the lever [B]
counterclockwise. This moves the cam [C] to the drum's side. After that, the clamper
sector gear [D] rides on the cam [C] and the gear [E] turns counterclockwise opening
the master clamper [F] for master ejection.
When the drum turns 13 degrees past the first drum position sensor, the main motor
turns off. Then, after 0.5 second, the drum references the first drum position sensor,
the master eject clamper solenoid [A] turns off, and the spring [G] returns the
opening cam [C] to the normal position.
