1054-Tape Insertion
2. Thread the leader end of the tape through the
guides (Figure 25) and insert in the take-up reel
slot so that the counterclockwise rotation of the reel
will properly wind the tape. This reel is a split-reel
type with the front removable for easy insertion and
removal of tape.
Note: To place a reel of punched tape into the center feed
reel for reading by the tape reader, position the roll with the
three-hole edge up. The inside (leading) end of the tape
must be twisted 90° so that the three-hole edge is toward
the back of the reader, and then inserted over the sensing
pins. Be sure that the tape feed holes align with feed pins.
3. If the reader stops because of the tape-presence
contact opening, operate the reader-stop switch to
the proper line or home position for the operation
before inserting another document or tape.
If this procedure is not followed, the reader will
start automatically once the tape table is lowered
with another document or tape in position. This
could damage the feed holes. This situation is also
prevented by sensing a reader stop code or de-
selecting the reader just prior to the end of the
document or tape.
Reader Operation -
1054
General Rules
1. Only one reader can operate in any one loop (Home
or Line) at any one time.
Note: Avoid setting the assignment switches for two readers
to
HOME
if the home-component-recognition special feature
is not installed. Reader conflict occurs if the home-reader
start button is pressed with both readers assigned to
HOME
(if the system does not have this special feature).
2. A reader can be transmitting to the line while the
second reader is simultaneously operating in a
home-loop.
3. A reader will not start if the assignment switch for
the selected reader (reset or programmed by compo-
nent recognition) is off when the reader-start button
(home or line) is pressed. However, if the assign-
ment switch is then properly positioned (home or
line), reading will start automatically unless a
reader-stop was initiated prior to the repositioning
of the assignment switch.
4. A reader, assigned to a home-loop operation, and
reading, is stopped by:
a. Sensing a reader stop code when the prog-dup
switch is set to
PROG.
If this prog-dup switch is
set to the
DUP
position, reading the stop code re-
sults in the code being punched but, in this case,
the code will not stop the reader.
Note: The setting of the stop code switch has no effect
in home-loop.
b. Positioning the reader-stop switch to
HOME.
c. Running out of tape.
d. A CR and LF, LF, or tab operation on a printer,
or a release,
DUP
or skip on the card punch.
e. A taut tape condition.
5. A reader assigned to a line-loop operation, and read-
ing, is stopped by:
a. Sensing a reader stop code with the stop-code
switch set to
SENSE.
See Stop Code Switch in the
1052 Printer-Keyboard and 1053 Printer section.
h. Positioning the reader-stop switch to the line
position,
c. Running out of tape, or
d. A taut tape condition.
6. When a reader reads a prefix code followed by the
component-recognition code for the alternate reader
it will:
Home Loop:
a. Stop the reader and transfer reading to the alter-
nate reader if the prog-dup switch is set to
PROG,
with the home component recognition special fea-
ture installed.
b. Allow the reader to continue reading but punch
the prefix code and/ or print the component-recog-
nition code with the prog-dup switch set to
DUP.
In this case, reading is not transferred to the
alternate reader.
Line Loop: Stop the reader and transfer reading to
the alternate reader.
