REMOVE A CARD JAM
The IBM 129 uses "fiber optics" in the read mechanism to
provide high reliability and quiet operation. Card jams can
normally be removed by pressing card release pushbutton
and by pulling jammed card gently, or by pushing pieces of
jammed card with another card.
Try
to assemble jammed·card pieces together to be sure
that all pieces have been removed and to facilitate
makeover of the card.
If
all pieces cannot be removed, try
the following procedure in punch mode:
1. Set PRINT and AUTO SKIPjDUP to OFF.
2. Set REC ADV JCARD FEED to MANUAL.
3.
R~move
any loose cards from card bed.
4. Manually select program O. (Keyboard is in alpha shift.)
5. Key
in all
80 columns, with
&, -,
and digits 0-9,
sequentially.
6. Manually insert a card at punch station.
7. Press REG.
8. Press card release pushbutton; hold it down through
step 9.
9. Manually select program O. (Press PROG SEL, then
data key 0.) Punchout follows; however, the card does
not move while you press card release pushbutton.
10. Tear a strip of card about 1-inch wide and use it (or the
special "type 129 card saw") to push out pieces of card
which may still be under the punch.
11.
Repe~t
this entire procedure, using DUP key for step 5.
Do the procedure several times if pieces of card are still
jammed.

Note: If card saw must be used, be sure to use only the
special "type 129 card saw" that is included with every
machine.
CARD INFORMATION
1. Cards with upper left or upper right corner cuts are
acceptable although printing may be affected by size of
cut.
2. Cards with lower corner cuts (except lower left corner
cut C-3, 30-degree, 0.130-inch base measurement)
cannot be fed.
3. Round corner cards are acceptable.
ACOUSTIC COVER
An acoustic cover for the card transport of the IBM 129 is
available to provide further noise reduction, in addition to
that resulting from the use of fiber optics sensing, elec-
tronic storage, and sound-reduced mechanical components.
The cover is similar to the acoustic cover for the IBM
29/59 macbine; it may be field installed.
KEYBOARD LOCKUP RECOVERY
The IBM 129 has several machine and keyboard interlocks
to prevent invalid or erroneous operation, to detect
potential errors, and to ensure accurate data during punch
or verify operations. Recovery procedures are:
