1055 Paper-Tape Punch
Controls (Figure 29)
Delete
Operating this button causes the tape punch to ad-
vance the tape by punching a delete code and a feed
hole. Delete codes can be punched continuously by
simultaneously pressing and holding down the delete
and feed buttons on the associated punch. A punch-
delete button is also located on the 052 if the home-
correction special feature is installed.
Feed
Pressing this pushbutton causes the tape punch to ad-
vance the tape by punching idle characters and feed
holes. Holes are continuously punched by holding the
button in the operative position. A punch-feed button
is also located on the 1052, if the home-correction spe-
cial feature is installed.
Tape Advance
This wheel permits the operator to feed the tape man-
ually forward or in reverse without punching the tape.
Note: If tape is moved forward, exercise care because no feed
holes will be punched.
Document Pressure Lever
This lever is located to the left of the punch station.
During tape punching this lever is manually positioned

to its left most limit so that it is not effective. For docu-
ment punching, this lever is moved to the right.
It
must remain in a raised position until after the docu-
ment is inserted, then lowered to an active position.
Tape Pressure Lever
This lever is located to the right of the punch station.
During both tape punching and document punching,
this lever is in a down position (active). However,
when tape is inserted, this lever must be raised until
the tape is properly positioned, then lowered.
Interlocks
Protective features for the 1055 include a tape-tension
interlock and a tape presence interlock. In the home
loop, either of these interlock conditions causes the
punch to stop punching; but the reader does not stop,
and the keyboard does not lock. In the line loop, either
of these conditions stops the punch, and causes the
receive alarm and data-check lights to come on. See
Receive Interlocks in the 1051 Control Unit Section.
Setup
Procedures
When the 1055 is being used with the system, the setup
procedure is:
Fon
TAPE
I. Place a blank reel of tape in the tape supply pan and
properly thread the tape through the guides.
2. Move the document pressure lever to the left so
that
it
is ineffective for tape operations.
3. Pivot the tape pressure lever up.
4. Take the leading end of the tape from the supply
pan and thread the tape with the outer surface of
the tape up for punching.
5. The tape should pass under the tape-tension lever,
the die, and the tear guide.
6. The tape is then threaded around the guides (Fig-
ure 30) on the side of the unit and inserted in the
take-up reel slot to permit counterclockwise wind-
ing of the tape.
Note: The tape reel is the split-reel type to permit easy
insertion and removal of the tape.
7. Lower the tape-pressure lever.
8. Press the feed key to punch several inches of tape
with feed holes and idle characters. This permits
self-aligning of the tape for proper punching reg-
istration.
