INTRODUCTION
The 43 Basic RO Teleprinter provides character-at-a-
time receive-only printer operation. Data reception
is normally provided at 30 characters per second (cps)
(300 wpm). *
The 43 RO Teleprinter may be connected to an
external communications device or contain an inter-
nal
data set and may be associated with a telephone.
A permanent connection via private line may also be
used in
the arrangements with an external device.
Calls
may be answered and disconnected automati-
cally over the telephone line.
In some arrangements the 43 RO Teleprinter may be
connected directly to a computer or remote terminal
which will control Data mode transfer.
*See reverse
side of directory card for a record of an
option exception that provides data reception at
10 characters per second (cps) (100 wpm) or any
other exceptions to standard operating features.
Messages are
printed with up to 132 characters per
line on printers equipped for 12 inch wide sprocket
feed paper. Sprocket feed paper may be fed from a
supply box or limited amounts can be placed in a
paper holder that clips on the rear of the teleprinter.
On friction feed printers, messages up to 80 charac-
ters per line are printed on 8-1/2 inch wide roll-type
paper.
The roll is held in a support attached to the
rear of the teleprinter.
The ribbon is part of a cartridge that can be readily
replaced
with the cover open. Replacement ribbon
cartridges can be obtained from Teletype Corporation
(see Page 6). An order form is included with each new
ribbon.
A pullout directory card holder under the front of
the teleprinter may be used to write in frequently
used telephone numbers and note any extensions
(see Page 9).
Note: The paper used with the sprocket feed
teleprinter is a new 12 inch wide sprocket feed. See
Page 6 for ordering information.

COMMUNICATIONS WITH DISTANT TERMINALS
• Establishing connection and transferring to the
Data mode automatically is basically under the
control of the communications device (modem)
over the switched-network or over private lines.
In some arrangements terminals are directly con-
nected to the distant terminal or computer. Use
of external devices should be specified locally
since
many variations are possible, ie, pushbuttons
on modem or on phone, if present, exclusion,
auto answer keys, etc .
• The procedures as shown below, that normally
apply
to operation of the controls of the termi-
nal, should
be followed:
• To Condition Terminal to Transfer to Data Mode:
4
ie, Place terminal in Terminal Ready mode:
1. Turn on ac power (see Page 2).
2. Clear
any alarm condition (paper-out,
cover
open).
3. Depress RESET key.
• Transfer from Terminal Ready to Data Mode.
The DATA key lights under control of the ex-
ternal device, if present, or distant station.
Note: Data can be received on-line only
when the DATA key is lit.
• Transfer from Data mode to Terminal Ready Mode.
1.
The RESET key is depressed.
2. Eight line feeds
are received after a paper-
out condition (sprocket feed only).
3. Printer test is initiated.
4.
Telephone call is disconnected for any
reason such as received EaT. See the back-
side
of the directory card for any exception
of the feature, Option 433.b.

PRINTER OPERATION
• Printer
The printer copies all received printable
data messages when the DATA key is lit.
• Signal Bell
The signal bell sounds when
characters are printed seven
characters before and at the
right margin, ie, margin at 80,
bell at 73 and 80. Also sounds
at left margin when back-
spaces are received, when a
bell
character is received or
when a paper-out condition
is detected. It may also ring
when a call is disconnected.
• Indicator Scale
• Margin
Setting
When power is turned on, the
left and right printing margins
are reset to 1 and 132 on sprocket
feed or 1 and 80 on friction
feed. They may be set or cleared
on-line by receiving escape
sequences. (See Page 15.) To
change either margin outward,
both must be reset.
The next printing location of the print head is indicated by the
print head marker at the print indicator scale after a 1 second
delay. The print head moves back when printing resumes or
when nonprintable characters are received.

It is your responsibility to keep the teleprinter equipped with sufficient paper and
ribbon. In addition. an adequate supply of these items should be ordered and kept in

Avenue, Skokie, IL 60076. An order fonn included with each new cartridge may be
used for this purpose or established ordering procedures may be followed for large
orders.
The ribbon should be replaced whenever it becomes frayed or print density becomes
light. After the "first few ribbons, replacement ribbons should produce three million or
more legible characters of printing.
Paper
