The master eject unit removes the used master from the drum. (!: Digital
Duplicators – Duplicating Process – Master Ejecting)
Procedure
The drum turns to the master eject position. Then the clamper [A] opens. The drum,
driven by the main motor can only rotate in one direction, clockwise (when viewed
from the front of the machine).
↓
Master eject rollers [B] pick-up the master’s leading edge and feed the master for
0.6 seconds into the master eject box [C].
↓
The clamper then closes.
↓
The drum then turns at 30 rpm while the master eject rollers continue to feed the
used master into the eject box.
↓
The drum stops after making about 1.5 turns. The master eject motor also stops.
The pressure plate [D] then compresses the used masters in the eject box.
• The capacity is 30 used masters (under normal conditions)
• The master eject process is skipped when the drum master sensor [E] detects no
master on the drum.
