6. Replace the cards removed from the punch feed hopper
in step 1.
7. Press START.
Punch Stop and Punch Check lights On
If any other light is on with the punch stop light, visually
check the last card in the NP stacker and correct it if
necessary. In the case of a card jam between the punch
check station and the stacker, check the last card read
by the punch check brushes and correct, if necessary.
To resume operation, after clearing any card jams, follow
the same procedure as described for "Punch Check light

Punch Errors (1402 Models
1.
3, 4, 52 and 6 With Punch
Feed Read Special Feature)
Punch Cheek light On
1. Remove cards from the punch feed hopper.
2. Run out the three cards in the punch feed.
3. Press CHECK RESET on the 1402.
4. Remove the last four cards from the NP stacker.
S. Duplicate inte new cards, the prepunched data from
the first two cards. If the B-light on the system console
is on (indicating a B-register parity error), perform a
storage s.can operation (starting at position 101) to
determine and correct the position (101-180) that
contains the parity error. Note the I-address for re-
starting after the scan.
6. Place the two duplicated cards and the third and
fourth cards in the punch feed hopper. Replace the
cards removed from the hopper in step 1.
7. Press START RESET on the system console.
8. Enter a restart address to start proceSSing at the program
instruction that had previously caused the first card to
be read by the punch feed read brushes. (Reconstruct
internal data, if neeessary.)
9. Set the mode switch to RUN and press START to
resume operation.
Punch Stop Light On
When only the punch stop light is on and a punch-feed-
read operation has occurred, all cards in the punch feed
between the hopper and the punch check station should
be reprocessed. Cards beyond the punch check station
and in the stackers have been punched and checked. A
card between the punch and the punch check stations
has not been checked; operation should be restarted
so that this card is repunched.
;Note: If neither a feed failure nor a card jam caused the
punch stop light to turn on, the stop may have been due
to a clutch failure. The last card in the NP stacker should
be checked.
1. Remove cards from the punch feed hopper.
2. Remove any jammed cards from the punch feed, and
run out any undamaged cards.
3. Press CHECK RESET on the 1402.
4. Duplicate, into a new card(s), the prepunched data
in the card (or cards, in the case of a card jam) that
was between the punch and punch check stations when
operation stopped. This card was punched but not
checked and must be reprocessed.
S. Place the duplicated card(s), and all other cards removed
from the punch feed (between the hopper and the punch
station), into the punch feed hopper in their original
sequence.
6. Replace the cards removed from the hopper in step 1.
7. Press START RESET on the system console.
8. Enter a restart address to start processing at the program
instruction that had previously caused the first card
(duplicated in step 4) to be read by the punch feed
read brushes. (Reconstruct internal data, if necessary.)
9. Set the mode switch to RUN and press START to
resume operation.
Validity light On
When only the validity light is on and a punch-feed-read
operation has occurred in the punch feed, the card just
read at the punch feed read station contains an invalid
character.
1. Remove cards from the punch hopper.
2. Run out the three cards in the punch feed.
3. Press CHECK RESET on the 1402.
4. Remove the last three cards from the NP stacker.
S. Visually check the first of these three cards. (This card
had been punched but not checked when the error
occurred.) Correct this card, if necessary, then replace
it in the stacker.
6. Correct the validity error in the second card (the error
card).
7. Place the second and third cards in the punch hopper,
and replace the cards removed from the hopper in
step 1.
8. Press START RESET on the system console.
9. Enter a restart address that will start processing at the
second card to be read by the punch feed read brushes.
10. Set the mode switch to RUN and press START to
resume operation.
Validity and Punch Check Lights On
If the validity and punch check lights are both on, two or
more error conditions have been detected in the punch
feed. Follow the same restart procedure as described for
