Operation
For form-feed operation, this disc can be punched
with the disc punch (see Figure 3-6) so that the
recognition of a FF code causes the line feed drive to
run quickly to the first line of printing on a new
form.
The vertical tabulation operates in the same manner
as the form feed. The programmable disc controls the
response of the Printer to a recognized VT code. This
operation is used for rapid consecutive line-feeds
within a particular form.
The VTFF is designed to help prevent mis-indexing of
a form if you should inadvertently press the VT
rather than the FF key. Recognition of a VT code
causes
either vertical tabulation or form feed
indexing, depending on which hole appears next on
the programmed disc. If there are no holes punched
in the disc or there is a malfunction in the sensing
mechanism, a timer will stop paper feeding within a
few seconds.
PROGRAMMING THE DISC
a. Mount the disc on the punch so that the
disc-key protrudes through the disc key hole
(see Figure 3-7).
b. By rotating the disc, set the desired number in
line with the VT and FF holes. This number
should coincide with the line position where
the form is to be started.
c. Press the punch in the FF hole to punch a hole
in the disc in line with the desired numbered
position.
d. Rotate the disc and punch a hole at each VT
position where the form is to have a vertical tab
stop.
OPERATING THE VTFF OPTION
a. Press a pre-punched disc over the keyed hub of
the disc wheel until it can be rotated (see
Figure 3-8). Rotate the disc until the key on
the wheel protrudes through the disc keyhole.
b. Press the FF key (or FORM FEED pushbutton
on RO or SR Printer). The Printer will line feed
to the first line position that is to be printed.
c. Using the Platen Knob, advance the form so the
first line to be printed is under the embossed
characters on the fingers. The Printer is now
ready to print.

SPLIT PLATEN PRINTER
The Split Platen (Pin Feed) Printer configuration
{Figure 3-9) is available with the TermiNet 300 KSR,
SR, RO and ASR Printers. This Printer configuration
is capable of printing dissimilar information on two
separate,
standard
size
forms
by
using
two
independently operated platens. The left hand platen
prints up to 75 columns on 8 1 /2-inch wide paper and
the right hand platen prints up to 26 columns on 3
1 /2-i nch wide paper. Each platen has its own
independently-operated manual paper advance knob,
paper supply and paper out sensor.
When the Split Platen Printer is first placed in ON
LINE or LOCAL mode, the left hand platen is
energized first while the right hand platen remains
idle.
In this mode, when the linefeed {LF) key is pressed,
only
the left hand form will advance.
Upon
recognition of the character sequence ESC 3 {from
local or remote source), the left hand platen will be
deactivated and the right hand platen will be
energized; linefeed will now advance the right hand
. form only. To return to left hand platen operation,
the Printer must recognize the character sequence
ESC 4. All normal Printer operations and standard
option functions (except Backspace {BS), as noted
below) remain operable in conjunction with the Split
Platen Printer configuration.
Pressing the BS key moves the print position to the
first print position on the right platen regardless of
current column location. This use of the BS character
provides a method to automatically tab to the right
hand
platen.
THEREFORE,
ON
THE
SPLIT
PLATEN
PRINTER,
THE
NORMAL
BS
BACKSPACING FUNCTION IS NOT OPERABLE.
Whenever the Printer is turned off briefly, then on
again {or whenever power is interrupted), the left
hand platen is automatically energized when power is
restored, regardless of which platen was energized
previously.
On Printers employing the Vertical Tab and Form
Feed (VTFF) option, the VTFF controls the left
hand platen only.
