(If 2540 is not performing PF R operation
and using stacker P1 .)
Punch Check Light
Sense Bit 3-Equipment Check
(If 2540 is not performing PFR operation
and is not using stacker P1 .)

(If 2540 is performing PFR operation.)
Restart Procedures
1. Remove cards from stacker P1.
2. Remove cards from hopper.
3. Open covers and remove any jammed cards from punch feed. Press punch start key to clear
feed.
4. Any card removed or run out from between punch station and punch check brushes should
be reconstructed, because it has been punched but not punch checked.
5. Place reconstructed cards and cards run out into stacker P1 in proper sequence ahead of cards
removed from hopper, and place this deck in hopper.
6. Press punch start key.
7. Reconstruct internal data in the system as necessary to restart at the Start 1/0 instruction
that caused the first card removed or run out to be read at the PFR station.
Note: In some programs, reconstruction of internal data may not be provided for. In that
case, restart the job from the last checkpoint.
1. Remove cards from hopper.
2. Press punch start key to clear punch feed.
3. Remove last four cards from stacker P1. The last two cards are blank; the first two should
be discarded.
4. Replace blank cards and cards removed from hopper in hopper.
5. Reconstruct internal data in the system as necessary to restart at the Start 1/0 instruction
that caused the first card removed from stacker P1 to be punched.
Note: In some programs, reconstruction of internal data may not be provided for.
In that case, restart the job from the last checkpoint.
1. Examine and correct, if necessary, error card, which is last card in stacker P1. (2540 auto-
matically routes error cards to stacker P1.)
2. Place this card in appropriate stacker.
3. Press punch start key.
4. The 2540 will force the card following the error card into stacker P1, also. Place this card
in the appropriate stacker.
Note: Because the error card and the card following it are both directed to stacker P1, the
program can correct a non-PFR punch check without operator intervention by
repunching both cards and directing them to appropriate stackers. The operator
can then discard all cards in stacker P1 at the end of the job.
1. Remove cards from punch hopper.
2. Press punch start key to clear feed.
3. Remove last four cards from stacker P1. The last two cards are correct; pre-punching in
the first two must be reconstructed.
4. Place the two reconstructed cards, the two correct cards, and the cards removed from the
hopper, in that sequence, in the hopper.
5. Reconstruct internal data in the system as necessary to restart at the Start 1/0 instruction
that caused the first reconstructed card to be read at the PF R station.
Note: In some programs, reconstruction of internal data may not be provided for.
In that case, restart the job from the last checkpoint.
