1.1
GENERAL DESCRIPTION (Figure 1-1)
The Model lOlA printer is a medium speed impact printer which uses a
9 x 7 dot matrix for character generation.
\
,- -
Figure 1-1. MODEL lOlA PRINTER (FRONT COVER REMOVED)
The .unit prints at a rate of 165 characters per second with an average
speed of 132 characters per second (in~luding the return time for the printing
head).
The printer is capable of printing 132 columns, with paper width varying
from 4 inches to 14-7/8 inches. The unit uses sprocket-fed paper with 6 lines
to the
inch vertically and 10 characters per inch horizontally. The printer
does not require special paper and can produce an original plus four copies.

Rev. C

1.2 LOGIC FLOW DIAGRAM (Figure 1-2)
The 132-character input buffer can receive parallel data at a rate of
up to 75,000 characters per second. If the input device transmits serial data
(100-9600 Baud), then an optional RS232 interface is required to assemble the
serial data, then transfer it in parallel to the input buffer in the printer.

HEAD MOTION
CONTROL
PAPER ~OTION
CONTROL
TIMING
Once a line of printable characters is stored in the buffer, head
motion is initiated by activat1ng the forward clutch, causing the print head
to move from left to right across the paper. With the head in motion, data is
transmitted from the buffer to the character generator. From there, character
write pulses
are sent to the driver circuits, which energize the print head
solenoids causing the print wires to form the characters on the paper.
Paper movement is initiated by a line feed, vertical tab and form feed
function.
The Vertical Format Unit (VFU) tape reader provides vertical tab
and top Of form spacing control by means of a perforated paper tape.
In addition, the printer recognizes the following special control codes:
bell, delete, select, de-select and elongated character, as described in
Section 1.3.3.
1-3
Rev. C

1.3 PRINTER OPERATION
Basically, all printer functions can be grouped into one of the
following three categories:
1) character printing, 2) paper movement, and
3) other auxiliary functions such as printer select/deselect, delete, etc.
1.3.1
CHARACTER PRINTING (Figures 1-3, 1-4)
A
small aluminum carriage supports the print head assembly. During
printing operation, the carriage travels along the print line from left to
right. Printing is accomplished by selectively firing the print wires as
the print head moves from left to right across the print line. Printing
impulses energize the print solenoids
and drive the print wires against the
ribbon,
paper an~ platen to form the characters in a dot matri~ pattern. When
the solenoids are de-energized, the wires are withdrawn so they are flush
with the surface of the jewel.
Each solenoid can fire independently up to
five times for anyone character.
F~gure 1-3 shows an example of the dot
matrix
forming the letter H. All character formations in the standard 9 x 7
dot matrix are
shown in the Series 100 Operators Manual.
JEWEL
~-A-~
Figure 1-3. PRINTING THE LETTER (H)
Figure 1-4. PRINT HEAD COMPONENTS
The print head (Figure 1-4) consists of the jewel, casting and seven
solenoids with attached print wires. The seven print solenoids and their
attached print wires are- arranged radially around the print head. The free
ends of the print wires pass through a wire guide at the front of the print
head, which properly spaces the wires so that the correct wire passes through
the correct hole
1'n the print jewel.
Printing action
is initiated when the input buffer has been filled or
a carriage return
(CR) code has been received. The print head then sweeps
across the page until a CR command is decoded at the buffer output or the head
reaches the 132-column limit (right) switch. At this time, the print head re-
turns to the left margin and an automatic line feed is performed. As an option,
the automatic line
feed can be disabled.
REV. H

1.3.2 PAPER MOVEMENT (Figure 1-5)
Paper can be moved manually by rotating the platen knob or automatically
by any of three paper movement commands: line feed, vertical tab and form
feed. .

CAM
PAPER

Figure 1-5. PAPER MOVEMENT MECHANISM
'v
FORM FEED
HOLE
A small independent motor not shown in Figure 1-5, provides the power
necessary to move the sprocket-feed tractors which control paper movement.
To move the paper, the printer electronics activates a line feed solenoid
which activates a clutch that mechanically links the motor to the sprocket-feed
tractors. .
To initiate a single line feed, the form feed solenoid is energized
from 15 milliseconds. For paper slewing, a dc level is applied to the form
feed solenoid allowing paper to advance until the Vertical Format Unit (VFU)
deactivates the level. Upon completion of the line feed command, a 60-90
millisecond delay is generated. This allows the clutch pawl and clutch
mechanism to return hole before another line feed is allowed.
To initiate a single line feed, the form feed solenoid is energized
for
15 milliseconds. For paper slewing, a de level is applied to the form
feed sol'enoid allowing paper to advance until the Vertical Format Unit (VFU)
deactivates the level.
The VFU is controlled by a paper tape, which uses one track for
top of form indication and one track for vertical tab. The movement of the·
paper tape is caused by direct mechanical linkage to the gear train which
drives the paper feed tractors.
1-5
REV. H

When the printer runs out of paper, a sensing switch activates a
two-second audible tone in a speaker located at the rear. The printer also
st~ps printing and lights the PAPER EMPTY light on the control panel.
1.3.3 SPECIAL FUNCTIONS
In addition to the printable characters shown in Appendix B, the
printer
can recognize the following special functions:
Carriage return
(Octal 015) - Initiates the printing of a line.
Form Feed (Octal 014) - Moves the paper until the next hole in Tape
Reader Channel 7 is reached.
Vertical
Tab (Octal 013) - Moves the paper until the next hole in
Tape Reader Channel 5 ;s reached.
Line Feed (Octal 012) - Advances the paper one line.
Delete
(Octal 177) - Initializes the printer electronics and clears the
buffer.
Bell (Octal 007) -Generates a two-second audible tone in the speaker
at the rear of the printer.
Select
(Octal 021) - Allows printer to receive data, same as acti-
vating SELECT switch.
De-Select
(Octal 023) -Inhibits printer from receiving data, same
as deactivating SELECT switch.
