[G]
After the master eject process is finished and the interrupter [A] is posi-
tioned in the first drum position sensor [B], the main motor turns on and the
drum starts rotating (30 rpm) in the reverse direction.
When the drum turns 160 degrees past the actuation position of the second
drum position sensor [C], the cam [D] is moved to the drum's side as the
master feed clamper solenoid [E] turns on.
When the drum turns 220 degrees further in the reverse direction, the sec-
tor gear [F] runs along the cam [D] and the gear [G] turns counterclockwise
to open the clamper [H]. At the same time, the drum stops and the clamper
remains open to clamp the master leading edge.
