1) 2 color printing (Red and Black)
2) High-speed bidirectional printing (2 line/sec, 29 or 44 columns per line)
3) 9-pin print head
4) Parallel interface (Centronics compatible)
5) Commands for expanded characters, inverted characters, emphasized
characters, red and black printing, and 10CPI or 15CPI characters etc. are
provided, which makes the printer very versatile.

2-3. Handling Notes
(1) Install the printer near an easily accessible socket-outlet.
(2) Place the unit on a flat and stable surface for operation.
(3) Do not connect the AC Power Plug to the same outlet used for other noise
generating devices (large motors, etc.).
(4) Be careful not to drop paper clips, pins and other foreign objects into the
unit.
(5) Wipe off dirt with a soft cloth soaked in alcohol or benzine. Do not use
Lacquer thinner, Trichlorethelene or Ketone solvents because they may
damage plastic parts.
(6) Use a soft brush, etc. for cleaning the printer mechanism and PCB.
(7) Keep hands out of printer while power is on.
(8) Do not attempt to print when there is no ink ribbon or paper in the unit. The
print head life could be severly reduced.
(9) If the paper is fastened tightly to the roll, the paper may not detach from the
roll when the end is reached.
If this happens, the no paper detection function and paper feed will not
operate.
(10) Always keep the printer cover attached when printing to prevent paper
jams, noise, and other problems.
(11) Always turn the power off before opening the printer cover. (e.g. When
renewing a ink ribbon)

Toggles between the on-line and off-line modes. The
printer will go on-line after turning power on.
Momentary operation of this button provides one
line feed. Pressing this button continuously will
cause continuous paper feed. If power is turned on
while pressing this button, self printing*1 will be
performed.
(9) Interface Connector Connects the printer to host computers. Check that
both computer and printer are off before connecting.
(10) DIP Switches
Allows for setting of various functions according to
user requirements.
(11) Peripheral Drive
Output
Connects the printer to the peripheral devices such
as Cash Drawer, Paper Cutter and Paper Take-Up
Device etc. to drive them.
*1 Self Printing
This printer has another convenient function, the
Automatic Test Printing. With the ink ribbon and
paper properly installed in the printer, turn the power
ON while holding down the Feed switch. Test print-
ing will start and stop again automatically.

4. INSTALLATION OF INK RIBBON AND PAPER
4-1. Installation of Ink Ribbon
(1) Turn power off, lift the Printer Cover up and remove it.
Note: Be careful not to touch the print head immediately after printing,
because it can get very hot.
Figure 4-1. Printer Cover Removal
(2) Unwind ribbon so that the spools are separated as shown in Figure 4-3.
Hold the ribbon taut as shown with the drive pins facing down and slide the
ribbonbetweentheprintheadandtheplaten. Whilekeepingtheribbontaut,
wrap one side around the black ribbon guide on the end of the platen and
droponespoolonthespoolshaft. Asyoumovethespooldownwards, move
the detecting lever aside to allow the spool to drop into place. Make sure the
spool drive pins engage with the spool drive holes. As the spool drops into
place there will be a click.
(3) While continuing to hold the ribbon taut, install the remaining ribbon spool
in a similar fashion.
(4) Turn the spool that rotates freely to take up the ribbon slack.

4-3. Paper Insertion
4-3-1. For Roll Paper
(1) Cut the Roll Paper end straight and square. Hold the roll so that the paper
comes from the bottom.
(2) Attach the Roll Paper to the Holders Paper by slipping one side of the roll
onto the Hub and pulling the other Hub out to allow the roll to slip in place.
(3) Insert the paper evenly into the Paper Insertion Slot.
(4) Turn the Power Switch “ON”, and press the FEED Button. The paper will
be fed into the unit.

4-3-2. RollPaperInstallation(WhenusingtheoptionalPrinterCover8340R)
When installing roll paper with the optional “Ptinter Cover 8340R”, please use
the following procedure.
(1) Turn power off, lift the Printer Cover up and remove it.
Note: Be careful not to touch the print head immediately after printing
because it can get very hot.
(2) Insert paper into the printer, and feed the paper so it extends 3 inches or
more above the top surface of the printer.
(3) Insert the paper into the slot in the “Printer Cover 8340R”.
(4) Install the “Printer Cover 8340R” on the printer.

4-3-3. Validation Option Installation
The validation printing requires the optional printer cover 8340R. Refer to
item 4-3-2 for the installation.
(1) Turn power ON.
(2) Enter the printer the validation mode.
(Refer to the control code “GS” in Chapter 5.)

Roll Paper Removal
Cut the paper close to the slot and use the feed button until paper has passed
completely through the printer.
Note: Do not try to remove the paper by hand as it could become crooked and
get jammed inside the printer.

GS
(1D)H
CODE
Validation printing instruction
FUNCTION
OUTLINE
This code causes the printer to perform validation printing
of a maximum of 32 subsequent characters (at 15 CPI, from
the thirteenth to the forty-forth column).
After the GS code is received, a maximum of 32 characters
should be input, followed by the LF code which indicates
the end of the validation printing data.
(At this time, control codes except FS, ENQ, CAN and SUB
codes, or any character received beyond the limit of 32
characters are ignored.)
When the printer enters the validation mode, the ribbon is
shifted up and the ON-LINE lamp blinks. (This lamp goes
on and off at a 0.5-second interval until the end of the va-
lidation mode.) Afterthematerialtobevalidatedisinserted,
and the LF button is pressed, the validate line is printed,
followed by a single line feed. When the check is removed
and the ON-LINE button is pressed, the printer returns to
regular mode and is set to ON-LINE status.
1) The print settings by commands (such as emphasized
mode and underline mode) are invalid only during val-
idation printing.
REMARKS
2) When the CAN code is received in the validation mode,
the printer returns to regular mode, and the mechanism
is initialized.
3) If the FS or SUB codes is received in the validation
mode, these codes are executed just after the printer
returns to regular mode.
4) In the validation mode, the LF button and the ON-LINE
button do not work except the above behavior.
5) If the printer has a Red black ribbon installed, the va-
lidate line will be printed in red.

units (Paper Cutter, Take-Up Device, Cash Drawer, etc.)
The 6P Modular Jack is used as the Drive Circuit. When using this circuit,
connect the peripheral unit cable to the 6P Modular Jack (cable is not included).
Note: Peripheral unit drive circuit connector only connects to peripheral units
such as cash drawers, etc.Do not connect it to a telephone.

Note: Make sure that the metal structural parts of the peripheral device are
connected to frame Ground (Pin 1) to provide a static drain path.
2. Control code
Codes for Drive Circuit control are ESC BEL n1 n2, BEL, FS and SUB.
Refer to the Control Codes in Section 5.
7-6. Error Condition Alarm Mode
If an error condition is detected during operation, the printer will stop printing
and cause the ERROR signal to go Low. All solenoids & motors will be de-
energized. It is necessary to turn the printer power off and on again in order to
recover from the alarm mode.
The printer can detect the following error conditions:
a. Motor Lock
b. Defective timing detector
c. Micro-processor out of program sequence

8. WHEN POWER IS SUPPLIED BY THE USER
When printer power is supplied by the user rather than through the accessory
power source unit, please be careful of the following points.
+10%
–5%
Note 1: The power supply must be +12V
2A or above. An electrolytic ca-
pacitor (C = 4700µF/25V to 6800µF/25V) must be connected across
the output of the power supply.
Note 2: A DC power plug is available as an option.
Reference: Design the power supply referring to the power supply circuit shown
below.
Note: A line noise filter must be used to prevent line transients from passing
through power supply. Filter design to be determined by environmental
noise requirements.
