Feeds the master into the clamper.
Procedure
• When the old master has been ejected, the drum is stopped at the master feed
position. The master clamper clamps the leading edge of the new master before
the drum starts to turn again.
•
The tension roller [H] normally presses against the master feed guide plate to
apply tension to the master during master wrapping. When the clamper opens, it
pushes the tension roller arms [I] and moves the tension roller away from the
guide plate to allow the master to be fed into the master clamper.
