file space
Significance
A card transport problem has occur-
red. It is possible for a card jam to
occur
in anyone or more of four read
stations
in the 1728 Card Reader.
CAUTION
Do not attempt to single-
cycle the machine. Damage
to the card transport or
punch head may result.
Call
customer engineering to aid
in clearing the jam.
Jam while reading:
1. Examine the transport area.
2. Remove all cards that have com-
pletely passed under the read
station.
3. The cards that have not com-
pletely passed the read station
have not been read.
Put these
cards back into the hopper.
Ready the card reader and
repeat the request via the
RP
option. The cards must be re-
cycled in proper sequence.
4. If the procedure results in fail-
ure, abort the read.
Jam while punching:
1.
Clear the jam.
2. If a card has only partially
passed the punch station, it has
not been punched correctly. Dis-
card the card.
3. Ready the card reader and type
RP. If any cards were damaged,
the operation may have to be
started over to obtain a readable
deck.
