Wrong handling of the printer may cause its performance declined and the product damaged. Please
read the notes below before handling.
1. Static discharge prevention must be made for installation and removal of the printer to protect IC
and other electrical parts. Connect it to the earth ground. It is also requested to remove the static
from body of the person before handling, especially, the input terminal.
2. Avoid excessive force to the input terminal for handling.
3. When any type of paper, other than specified in this manual, is used, it may cause deterioration
of the print quality and thermal head reliability.
Examples of troubles
1) Print quality deterioration by using low sensitivity paper.
2) Thermal head wears due to roughness of paper surface.
3) Sticking between heat receipt layer and thermal head, and vibration noise during printing.
4) Print ink disappears on low print durability paper.
5) Electrolyte corrosion on thermal head due to low quality of heat receipt layer.
4. Avoid printing with no paper loaded. It damages platen and thermal head, printer life will be
shorten.
5. Do not scrabble thermal head with sharp edge or something hard, or give impact. The heat
element may be damaged.
6. Set the power of printer off before connecting or removing connecters.
7. When printing in high speed under low temperature of high humidity environment, the paper may
be stained by moisture that appears from paper, or the printer may have condensation. Avoid
dew from dropping down to the thermal head that may cause electrolyte corrosion. Turn the
power off until any dew is removed.
8. The printer is not protected from water or dew formed. Do not water the printer or handle it with a
wet hand, which may cause damage to the printer due to short circuit, or heat or fire.
9. The printer is not protected from dust or dirt. If it is used at dusty place, the thermal head may be
damaged or paper feed is not operated properly.
10. When cooling the printer with a fan, avoid the printer’s paper outlet from locating fan’s air inlet. It
may cause mal-function of printer.
11. Reflection type of infrared ray sensors are used at some locations in the printer. Direct sun light
may cause mal-function of printer. Avoid from such a location for installation.
12. This printer does not support any operations caused by the commands or control commands not
specified in this manual.
Please use both hand to holding the printer.
13.
14. In order to prevent excess current, please put elemental device to external 24V power line
(Please refer to the power supply specification for the details), and also put fuse.
15. Please plug off the printer when you do not use the product for a long time. Please also insert
paper between the platen.
16. When paper jam occurred in the print head, please make sure to slowly remove the paper to
paper exit direction after head up status.
17. The product is designed to use with general electronic devices (Computer, PC, OA, others). This
is not designed and not guaranteed to use with extremely high quality, high reliability product or
product whose failure may danger human life (Atomic power control device, aerospace aircraft
devices, Transportation devices, Traffic signal devices, Ignition control devices, Medical devices,
other safety equipments: we call “Specific application” thereafter). Users take full responsibility
for using with such specific application.
18. The product uses part that includes GaAS (Gallium arsenide).Please do not break the product,
no chemical splitting ,otherwise it may harm human with such part broken pieces.

*1: A sufficient volume of power supply is required to maintain print quality due to high peak current that
may run according to printing.
*2: If power supply cable is excessively long, the operation may become unstable. Cable should be
made as short as possible. If not available, connect cables near the printer and place an electrolysis
condenser of 2200µ between power supply and ground. Voltage resistance should be higher than 35V.
*3: For preventing from static electric discharge, make sure to connect FG wire.

4.1.3 Rewriting Flash ROM
Please do the following procedure to rewrite a program in a Flash ROM. Send the program from
the host, and turn off the powe after confirming the ALM LED turns off completely.
1) Switch operation when rewriting the firmware program
Head up lever: Head up
Feed switch: ON (press) Entry swich: OFF Turn the power on, the ALM LED start flashing slowly, then release the feed switch.
2) Switch operation when rewriting boot program
Head up lever: Head up
Feed switch: ON (press) Entry swich: ON (press) Turn the power on, the ALM LED start flashing slowly, then release the feed and enrty switch.
4.1.4Setting of Memory switch For setting or changing Memory switch, first load a roll of paper, then follow the below
procedure for mode setting (1) and switch setting (2).
After completion of the settings, it automatically operate software reset. Please confirm the
setting result by self print.
1)Mode setting Head up lever: Head down Feed switch: ON (press) Entry swich: ON (press) Then turn the power on, it print "** MEMORY SW SETTING MODE **". This is the
setting mode. You may release the Feed and Entry switch.
2)Memory switch setting Setting starts from Memory switch S1-1 to S1-8, and from S2-1 to S2-8. After change to the SETTING MODE, the LED start flashing.
・Press Feed switch when the LED is on, memory switch setting is on, and the result will
be printed.
・Press Feed switch when the LED is off, memory switch setting is off, and the result will
be printed.
Please continue such setting 16 times to complete all the settings.
If you would like to cancel the setting in the middle, please head up and press the feed
switch once, then head down.
If you change the setting when head up state, such change is not effective.
1) By performing self-diagnostic print following items are checked.
a) Proper function of control circuitry
b) Proper function of printer mechanism
c) Print quality
d) Control F/W version
e) Memory switch setting status
f) Correct function of paper out sensor
g) Head wide and head rank (automatically detected)
2) Start and end of self diagnostic print
Set the power on while pressing the FEED switch and release the FEED switch after the printer
mechanism activates to start self-printing.
The self diagnostic print automatically ends when a preset number of characters are finished
printing. While printing, the printer is in Off-line mode.
4.3 Operation panel
Operation switch is attached at the side of the printer.
1)PO (green) [Power lamp]
It is on when power is supplied to printer.
2)ALM(red) [Alarm lamp] It will be on or flash when printer is in an error status.
I will be flash/on/ off when rewriting to the Flash ROM
3)ENTRY [Setting switch] It is the switch when change the setting of memory switch.
It is used when rewriting to the Flash ROM.
4)FEED [Feed switch]
It is a feed switch for paper feed.
It is used when the memory switch setting mode, memory switch setting,
rewriting to the Flash memory mode set, and self print.

2) Return to normal status from error statuses
Remove causes of error statuses and turn the power on again or input the /INIT signal to
return to normal. When this process is activated, at the time of power switch turned off, the
printer will be initialized, so that settings are required again.
If data remains in the buffer, attention should be paid
4.5 Buffer full print
If there remains data in the buffer after one line of data is received, printer automatically prints
preceding data. The volume of buffer full data varies depending on ASCII characters or bit
images.
If you insert paper to the printer mechanism, paper will be automatically loaded. Please make sure
to insert the paper propaerly so the sensor will detect the paper.
