Note:
If
correction-card
punching
is
not
desired,
use
FEED
or
CLEAR,
and
continue
the
verify
operation.
The
FEED
key
allows
manual
or
auto
dup
in
the following record.
The
CLEAR
key
prevents
dup
in
the following record.
The
error
card
is
stacked
with
no punches
in
column
8
1
When
a rewrite
has
been completed
in verify
mode,
or the
record has
been
released,
column
81
is
not
punched
in
the
original card. If
punching
in
column
8
1
is
desirable
(because
of
verify-operator
error,
and
the card
is
correct as
originally
punched),
the card
must be
inserted in
the hopper,
fed,
and
then
verified
without
error.
