Adding Cards
Removing Cards
Press MANUAL CYCLE twice to move the last two punched cards into the output stacker.
It is good practice to press the control an extra time and get a blank card on the back of
the deck.
When a program punches more than a hopperful (800 cards), the operator either removes
cards when the full output stacker causes an alert and stops the punch or removes cards
before the stacker is full.
Normally the operator merely presses HALT, removes all cards, presses OPERATE/
RESET to continue punching, then stacks the punched cards on the joggling plate. Cards
come into the stacker face down, with the first punched card on the bottom of the stack.
Cards must be kept in sequence when removed in this manner.
Experienced operators
sometimes
remove cards without interrupting punching.
This
procedure requires special care to prevent jamming of cards as they come into the stacker.
A handful of cards must be grabbed at just the right time,
when a card is not moving into
the output stacker and while the stacker plate is in the up cycle of its oscillating up-and-
down movement.
The cards must then be pulled out very quickly. Normally, it is easier
to halt the punch for the few seconds it requires to remove the cards.
Emptying the
Chad
Box
The chad box of the CPZlOO card punch is next to the output stacker. If the card punch
is operating continuously, the Operator should empty the chad box frequently enough to
prevent the punch from halting because of a Chad Box Full alert. To do this, he presses
HALT to stop card movement, removes and empties the chad box, and then returns it to its
original position and presses OPERATE/RESET. If the chad box is not replaced correctly,
the punch will not operate.
'
The CHAD BOX FULL light remains on while the-box is not in place.
