There is also a stacker jam release at each stacker entry point. The stacker jam release
is operated to allow the mechanism to swing away from the stacker drum to release jammed
cards. (See Figure 6.)
Each jam release is interlocked so that the release must be in place before power can be
turned on.
With these new features, there is an excellent chance of recovering jammed cards in a
condition that allows reproduction inakeypunch. The devices also save much time in clearing
jams.
The normal output stacker holds at least 2000 cards, while the auxiliary output stacker holds
at least 1000 cards. In each stacker, the stacker full switch is activated by the pusher plate
when the stacker becomes full.
The switch stops card feeding and leaves the card reader
in an. inoperable condition.
