After the master eject process had completed and the interrupter [A] is
positioned in the first drum position sensor [B] (drum home position), the
main motor will turn on and the drum will start rotating (30 rpm) in the reverse
direction (opposite to the printing direction).
When the drum rotates 160 degrees past the actuation position of the second
drum position sensor [C], the master feed clamper solenoid [D] will energize
and cam [H] will move towards the drum.
When the drum turns another 58.5 degrees, the sector gear [F] will rotate
upwards as it contacts the cam [H]. This will engage the sector gear and gear
[E], which will turn counterclockwise to open the clamper [G]. At the same
time, the drum will stop and the clamper will remain open, ready to clamp
onto the leading edge of the master.
