Operator's Guide
This publication describes the procedure for preparing
the units of the 1440 system for systems operation and
the sequence of the steps for manual operation of the
console to perform separate functions. Each unit is
described individually with power off and power on.
IBM 1442 Card Read-Punch
With the power off, inspect the card transport area of
the read punch (Figure 1) to see if the unit was
cleared after the last operation.
Standing behind the machine lift the top cover by
grasping the left end of the cover and raising it up to
the right. When the cover is up, the operator can in-
spect the card transport area. If a card in the transport
area cannot be run out by pressing the non-process Figure 3. IBM 1442 Punch Station
runout key with power on, the card can be removed
by lifting the plastic card guides that cover the card Stackers
path. These guides are held down by magnetic latches. With the top cover open, raise the stacker feed-roll

the complete bar is free of the guide (Figure 6).
Typebar Installation
Insert the typebar into the guide, and push it to the
left until the bar is stopped. When the bar is stopped,
it is at the point to mesh with the gear that is con-
trolled by the typebar insertion wheel. By pushing on
the typebar with one hand and rotating the wheel with
the other hand, the bar is moved to the left. This
should not require any more pressure than it did to
remove the bar. The rotating of the typebar insertion
Figure 4. IBM 1443 Printer wheel to the left moves the typebar until the notch in
the flag aligns with the point indicated by the decal
on the top of the typebar guide. This position applies
to the 39-, 52-, and 63-character sets. The 13-character
set bar-alignment position is the right edge of the
upper section of the Rag instead of the notch.
After the typebar is inserted and aligned, select the
correct mode for the character-set mode switch, lo-
cated on the right side near the typebar guide.
Turn the typebar switch on, and the printer is ready
for operation.
Forms Insertion
Forms can be inserted into the 1443 printer by two
methods. One method is to feed the form up through
the forms guides from underneath the machine until

easily into the guides and the area between the type-
bar and the paper. This also eliminates the possibility
of getting the ribbon caught in the fingers of the type-
bar and causing damage to both the ribbon and the
typebar.
Typebar Removal
To remove a typebar from the 1443 printer, the follow-
ing procedure is recommended:
1. Turn the typebar switch off. This switch is located
next to the typebar mode switch at the right of the
carriage (Figure 5).
2. Turn the typebar insertion wheel (Figure 5), which
is also located on the right side of the base between
the carriage and the typebar switch, to the right
until the typebar stops moving. When the typebar
has reached its limit of travel to the right, it is dis-
engaged with the typebar insertion wheel. The Figure 6. IBM 1443 Typebar and Guide

the belt is positioned on the outside gears, the spacing
is for 6 lines to the inch (the belt is on the large gear
of the lower set and the small gear of the upper set).
The inside gears (nearest the carriage side plate) are
for 8 lines to the inch.
When the belt is positioned, reset the tension by
pressing the latch lever in front of the tension release
lever. This belt tension should be set light, with only
sufficient tension to keep the belt in position on the
operating gears.
Close the cover and the carriage vertical line spacing
is set.
c' Installing Carriage-Control Tape
1. Raise the counterbalanced cover of the printer to
gain access to the tape-reading mechanism.
2. Turn the feed-clutch knob to disengage the clutch.
3. Raise the brushes by lifting the latch on the side of
the brush holder (Figure 7).
4. Place one end of the loop (with the line numbering
on left) over the pin-feed drive wheel so that the
pins engage the center drive holes.
5. Place the opposite end of the loop around the ad-
justable carriage-control-tape idler.
6. Remove the excess slack from the tape by loosening
the locking knob (Figure 7) on the idler and mov-
ing the idler in its track. Tighten the knob when the
