5. Miscellaneous informational literature
If any of the first 4 is missing or damaged notify your dealer immediately.
Note: You also need a cable to connect the printer to your particular computer.
You should obtain the appropriate cable which is compatible with the cable
to use for C -80 Type I type printer with your particular computer, from
your dealer.
If you use a non-standard type cable, make sure it is wired properly refering
Appendix C.
Setting up
Before starting to use your printer, you should make sure that it is in working
properly. This procedure includes checking for obstructions in the path of the
printer head or paper feed and that the printer ribbon is properly in place. Follow
this procedure.
1. Lift and remove the plstic top cover to expose print head and mechanism.
2. Remove shipping screw(s).
Carefully lift front of printer unit and make it stands as the bottom of case be
vartically face to you and hold the unit by the one of your hand on the soft
surface — see Figure 2. Then, remove the shipping screw(s) with a hillips-
head screw driver. After it is removed, gently back the unit to lay flat on a firm
surface, position the printer front be face to you.

4. Internal selector switches (DIP switch).
There are 12 different switches inside the printer case, they can be set to make the
printer functions wide variety of print features — see Appendix E.
To get the switches, the case has to be opened in the manner of followings — see
Figure 4 & 5.
CAU ION: Please, refer to SECT ON C, 5. before open case. Any time you
attempt to open the case, the power line must be disconnected.
a. Remove the ribbon cartridge.
b. Remove the platen knob by pulling straight out, with firm steady pressure.
c. Locate the unit on the top of table with the portion of case screw be outside of
table edge so can use the screw driver from bottom side of case, one screw at a
time, remove the screw then with repositionning the case remove the all screws
one by one.
d. Hold the both side of upper case and gently lift and push back towards back and
upper way so the portion of case below the tractor mechanism got by the tractor
blocks — to make it easy, move the right side tractor block to left as far as it can
be pushed over.

Caution : There are the lead wires connecting the key switch portion of upper case
to the main electronic circuit board on bottom case, so after the upper
case has been removed, do not it too far away as to strain the lead wires.
e. Then, taking treat care, tip the upper case gently to the right so it can lie to the
side of unit.
f. The circuit boards are now exposed to you. Ref ering Figure 6, locate the
selection switches.
g. With refering Appendix E, set the switches.
h. Reversing above procedures, put the case back together and tighten the screws.
The printer case assembles the same way it as disassembled.
5. Cable connection.
Before connect the cable, be sure the computer and the printer are turned FF.
Follow these steps to connect your printer to your computer — see Figure 7.
a. Place the printer in a convenient location close to the computer.
b. Be sure you have the right cable and connect it on to the receptacle of connecter
on back of printer unit. Double-check to ensure that the cable is in place and
locked. It may take a firm puch on the connecter to secure the clips.
The other end of cable should not yet be connected to your computer at this
stage.
6. Set the wire rack.
As shown on Figure 8, set the wire rack which is a paper separator, it allows the
paper to feed smoothly into and out of the printer.
7. Installing the paper see Figure 9.
a. Position the paper on the floor behind and below the printer.
b. Pull the paper release lever and paper bail toward you.
c. Feed the incoming paper above the wire guide of rack but below the wire frame,
into the slot and right on around to the tractors. Move the tractors as necessarry
to match the paper hole spacing. pen both tractor covers.
d. Position the paper holes on top of the tractor teeth and close the covers. Adjust
one or both tractors so the paper is entered as you wish ft, and is hold firmly in
7

e. Feed the paper forward with the platen knob.
f. Set the paper so a perforation between sheets is positioned just slightly below the
top of the ribbon.
g. Adjust head positioning for print image if necessarry, after made print test. At this
stage, just acknowledge the location of adjusting lever but should not touch the
adjustment that should been made by factory. — Refer Figure 10.
Note: While using the tractor for paper feed the release lever should be kept in the
R L AS position.

SECTION C
OPERATION
Definitions of some terms often used.
Before looking at the printer in detail, some terms should be defined first so that you
can understand them more easily and in less time. They are:
ASCII code
Escape codes
4- ” symbol
2, D and H
If you are already familiar with the above terms, skip the following.
ASCII code.
Characters in computer systems are represented by groups of bits. The various
groups of bits that represent the set of characters that are the alphabet ” of any given
system are called a coding system, ” or simply code ” . Codes for representing the
information vary in relation to both the number of bits used to define a single
character in the assignment of bit patterns to each particular character.
The sending and receiving equipment must be programmed to acknowledge the
code used in computer systems.
The CP-80 Type I has character set of 96 in normal font, 96 in italic font and
control codes. In addition it has 32 semi-graphic fonts so you can assemble the
graphic drawing by using codes — see Appendix A, those characters are put in
some addresses of the ASCII code table instead of the standard characters.
All those can be accessed by a particular control code (or the Dip switch).
The selection of which one to use is up to you if your host computer has an 8-bit
data bus line.
Escape codes.
In a lot of control codes that the Printer has, you might be confused by the word
Escape ” . Some alphabetical letters and some numbers follow it. Each of them
causes a special function to the printer i.e.
(1) To format a sentence.
(2) To do emphasized printing.
(3) To select paper end detector programmably.
(4) To set column length.
(5) To underline characters.
(6) To print superscript/subscript characters.
(7) To do bit image printing.
(8) Others.
Generally, printer control codes, especially like Escape ” i.e. CHR$ (27) are not
standarized. Every computer and printer manufacturer applies its own meaning to
such codes.
The Escape ” codes used in the printer should not confused with the Escape ” key
which some computers have — so familiarize yourself with these control codes.
10

“ + ” symbol
You will often see “ + ” symbol in the explanation or description of control codes in
this manual.
This symbol is used for legibility only and may not be input in your actual program.
2. D (or Dec.) and (or ex.)
( ) 2. ( ) D and < > respectively represent binary, decimal and hexadecimal
numbers.
1. Switches and indicators.
There are three switches and four indicators on the control panel and one power
switch on the right side of the printer case. Acknowledge its locations to become
familiar with operation of printer — see Figure 11.
a. Power switch:
Controls primary AC power to the printer. Check the paper is
properly set in the printer before turning this switch.
b. ON LINE switch:
When the power switch is turned on the printer enters the
On-line mode and can be utilized in conjunction with a host
computer.
Depressing the On-line switch will set the printer in the Off-line
mode and cause the green light to go out, it toggle the mode
from On-line to Off-line to On-line alternatively.
The switch does not function while the printer is actively
engaged in printing.
The printer is automatically placed Off-line if the paper supply
is exhausted or if a mechanical error occurs in the printer.
The operation of the line feed and form feed switches are
effective only while the printer is Off-line mode.
c. FF switch:
When this switch is depressed once, the paper is advanced
(form feed)
vertically to the next top of form position. This switch must be
depressed while the printer is Off-line mode.
The top of form posit ion is initialized when the power switch
is turned on, when IN IT signal is applied to the interface
connector, or when the ESC @ code is input. Therefore,
before turning the power switch on to start operation, set the
paper at the appropriate top of form position.
d. LF switch:
The paper advances while this switch is being depressed. The
(line feed)
line spacing is determined by ESC A + (n)D code.
The line feed operation is prohibited while the printer is
actively engaged in printing.
e. Indicators:
POWER — Illuminates while the AC power is on.
READY — Illuminates when the printer is ready to accept
data.
ON LINE — Illuminates when the printer is in the On-line
mode.
PAPER OUT — Illuminates when the paper supply is near its
end.
11

2. Buzzer.
The buzzer is located inside the printer, and sounds for about 0.3 second when the
printer receives BEL code CHR$ 7), and also when the paper supply is near its
end.
3. Paper end detector.
a. When the paper end detector sensing switch located on the paper guide)
detects that the paper is nearly exhausted, the signals on the interface connector
change to the following status, and the printing oepration stops.
To reactivate the printing, take the following procedure as shown in Fig. 12.

Figure 12. Flowchart of paper out status release procedure.
b. When the printer falls into paper-out status, it is automatically put in the OFF-LINE
state and paper advancement can be performed by depressing the LF switch.
After setting new paper in the printer, depress the ON LINE switch to that the
printer may resume operation.
c. There is another way to start the printer, again when it falls into paper-out status,
set new p aper in the printer and turn the power switch off and on again, or apply
the I NIT signal. In this case, all previously established datas are cancelled.
12

d. The paper end detecting function is useful to prevent erroneous printing when
the printer is out of paper. If printing of characters up to the last line is to be
continued, the paper end detecting function may be made invalid by either of the
following two methods.
(1) Set the DIP switch pin 1 3 to the ON position, and the paper end detecting
function will become invalid.
(2) Enter control code “ ESC 8 ” and the paper end detecting function will become
invalid.
4. Self test.
The CP-80 Type I has a self test function.
The self-test function is pre-programmed and can be performed by turning the
power switch on while depressing the LF switch. All characters provided by the
internal software are printed out by this operation.
Notes: To check all interface logic including the interface connector, proceed as
follows: _ ________
(1) Connect ACKNLG signal (pin No. 10) to STROBE signal (pin No. 1)
with a lead wire.
(2) Turn the DIP switch 2 3 to ON to effect auto-line feed.
(3) Set the adequate ASCII code data to be printed. To obtain low logic
level signals, connect the data transfer line required for printing (pin
Nos. 2 to 9) to GND level (pin No. 33, etc.).
Example of printing “ Z ” “Z ” = (90)D = (01011010)
in this case, connect pin Nos. 2, 4, 7 and 9 to pin No. 33.
5. Setting of DIP switches. Refer to Appen ix E.
In order to suit the user ’ s specific requirements, desired control modes are selectable
by the two built-in DIP switches. The DIP switches (SW1 and SW2) located on the
main circuit board are shown in Fig. 6. Internal switch location.
Note: The most of functions selectable by DIP switches can also be selected by
control codes, so be sure it is desirable to set DIP switch before open the
case.
13

SECTION D
CONTROL CODES
1. Control codes in the text mode.
With the CP-80 Type I two standard operation modes are available. One is the
Text Mode which prints corresponding characters on normal ASCII coded inputs,
and the other, the Bit Image Mode which permits printing o pictures and images in
dot con igurations. The Text Mode is described in this section while the Bit Image
Mode is covered in the ollowing section.
The CP-80 type I has been designed as a terminal unit capable o various so tware
controls. When control codes are trans erred to the printer, respective unctions
governed by these codes such as orm eed, line eed, etc. are excuted immediately.
In order to permit the printer to ully exhibit these unctions, care ul reading and
thorough understanding o the ollowing control codes are recommended. In this
section, irst the control codes in test mode are classi ied into groups. These two
modes are not ully independent o each other in that parameters set in the Text
Mode are also e ective in the Bit Image.
a. Print action codes.
CR .......................................... Carriage return
LF (or VT) .............................. Line eed
FF .......................................... Form eed
b. Paper formatting control codes.
ESC D, HT .............................. Tabulation
ESC Q ...................................... Column length
ESC 0, ESC 1, ESC 2,
ESC 3 + n, ESC A, ESC J ... Line spacing
ESC C, FF .............................. Form length, orm eed
ESC N, ESC O ...................... Skip-over per oration
c. Character designation codes.
SO, ESC W, DC 4 ................ Enlarged character printing
SI, DC 2 ................................ Condensed character printing
ESC E, ESC F ...................... Emphasized character printing
ESC G, ESC H ...................... Double printing
ESC S, ESC T ........................... Subscript/superscript printing
ESC --(minus) ...................... Underline printing
d. Other codes.
ESC @ ..................................... Printer initialization
ESC 8, ESC 9 .......................... Selection or deselection o the paper end
detector
BEL .......................................... Buzzer
BS .......................................... Back space
DEL ............................................ Delete
NUL .......................................... Null
ESC K, ESC L ....................... Access code to Bit Image mode
14

ESC II ........................................ Unidirectional printing set, reset
ESC # .................................. Accept eighth bit “ as is ” from computer
ESC 4 ...................................... Italic character set O
ESC 5 ...................................... Italic character set OFF
ESC < .................................. One line unidirectional print.
Prints current line only from left to right.
ESC = .................................. Clears eighth bit.
(i.e. sets to zero.)
ESC > .................................. Sets eighth bit to 1.
2. Print action codes.
a. CR (carriage return)
When the CR code is t ransmitted to the print buffer, all data stored in the print
buffer is printed. When AUTO FEED XT (pin o. 14 of the interface connector)
is at “ LOW ” level, the paper is advanced one line automatically after the
executioon of printing by the CR code.
otes: (1) When 80 columns of print data (including spaces) are continuously
received and the following data is valid and printable, the printer
automa tically begins to pr int the data stored in the print buffer. (In this
case, if AUTO FEED XT is at “ LOW ” level, the paper is advanced one
line after printing.)
(2) If no data procedes the CR code, or if all preceding data is SPA CE, the
carriage as sembly does not operate. Under this condition, if AUTO
FEED XT is at “ LOW ” level, only the paper is advanced one line.
(3) When all 80 columns of data are SP ACE, the carriage a ssembly does
not operate. Under this condition, if AUTO FEED XT is at “ LOW ”
level, or if the DIP switch pin 2 — 3 on the main circuit board is O , only
paper feeding is performed.
b. LF (line feed) or VT (vertical tabulation — functions same as LF)
When the LF code is input, all data in the print buffer is printed and the paper is
advanced one line If no data precedes the LF code, or if all preceding data is
SPACE, only paper feeding is performed. For example, if the data is transferred
in the order of DATA — CR LF, data will be printed by the CR code, and
when the printer receives LF code, it only carries out one line feed, because
no print data precedes the LF code.
c. FF (form feed)
The FF code causes the printer to execute the printing of all data stored in the
print buffer and advances the paper to the next predetermined top of form
position.
15

Notes: (1) Th e top o f form is determined when the power switch is turned on or
the I NIT signal is applied, or when the ESC@ code is input.
( ) If the form length per page is not set, one page length of form is
regarded as 66 lines set in the ON position.
(3) The form length can be set by ESC C 4- (n)D or ESC C 4- (0)D + m as
described in this manual.
3. Paper formatting codes.
a. HT (horizontal tabulation)
The HT code carries out the horizontal tabulation to a predetermined position set
by “ ESC D ” (up to 8 positions). In the absence of any predetermined HT
position, the HT code will be ignored. In enlarged character mode, two non 
enlarged characters correspond to one enlarged character.
b. ESC D 4- n1 4- n + ... + nk + NUL
(1 < (n)D < 14 , k < 8)
This code specifies the horizontal tab stop position, “ n ” denotes column position
where the print head stops. The first 8 tab stops per line are recognized in the
printer, and subsequent tab stops are ignored. The tab stop positions can be
specified up to 80 columns in normal character mode and 14 columns in
condensed character mode. The excess tab positions set by the DIP switch or this
code will be ignored.
1 < n < 80 in normal character mode
1 < n < 14 in condensed character mode
In enlarged character mode, two non-enlarged characters must be set as one
character. The NUL code should be input as the command for the termination of
the tab set sequence, and the lack of this code will cause incorrect data printer *t.
