Pick up the master and feed it into the master eject box.
Procedure
1. When the clamper is open and the master's leading edge is released from the
clamper, the master eject motor turns on for 1.0 s to pick up the leading edge.
2. Then, the clamper motor reverses to close the clamper.
3. The drum then starts turning at the slower speed (30 rpm). At the same time,
the master eject rollers turn again to feed the master into the master eject box.
4. When the drum reaches the master feed position, the master eject and drum
motors stop. The master feed position is 121 encoder pulses (43 degrees) after
the feed start timing sensor is actuated.
5. During this process, the master eject sensor [E] detects master eject jams. (
