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.
13. Please use both hand when you hold the printer.
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, 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

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.
※This is only applicable for Serial interface.
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

4.1.4 Setting 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 Platen: Close Feed switch: ON (press) Entry swich: ON (press) Turn the power on, initialize the print mechanism, then release the Feed and Entry switch.
It print "** MEMORY SW SETTING MODE **". This is the setting mode.
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.
・It print the switch number you are setting.
・Press Feed switch, the memory switch setting will be OFF.
・Press Entry switch, the memory switch setting will be ON.
Please continue such setting 16 times to complete all the settings.
※ All setting will not be effective If you turn off the power during the setting.
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
2) Start and end of self diagnostic print
Turn on the power while pressing the FEED switch and release the FEED switch after
initializing print mechanism. Self diafnostic print will take place.
The self diagnostic print automatically ends when a preset number of characters are finished
printing. While printing, the printer is in Off-line mode.
4.1.6 Paper sensor
Paper end sensor equipped in the paper course of the printer mechanism, and it detects paper
end status. It stops printing by error bit ON, when detected the paper end.
The sensor can not detect paper end of the roll with glue. Please load the paper when
detected the paper end.

When the above errors are detected (except transmission error and paper empty end error), printer
stops all operation and turn on the error bit of the status. ・It turns ON error bit of the status information.
2) Return to normal status from error statuses
Remove causes of error statuses and turn the power on again or input the /RESET 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
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 ANK, Kanji or bit images.
4.4 Partition drive
The fixed partition drive (No partition or 2 partitions) or automatic partition drive can be selected
by the memory switch and or the command. It should be selected according to the power supply
capacity and print duty.
1) Partition drive select

MS1-3 Partition drive select 2 partitionsAutomatic
※2 partition or automatic partition can be selected by the memory switch by default. No
partition can be selected only by command.
※2 partitions select may decrease print speed.

No partition 2 partitions
NP-266S Less than 248 dots Higher than 249 dots
NP-366S Less than 352 dots Higher than 353 dots
※ Automatic partition drive will change the print speed according to print ratio. Print noise
may occur.
※ The default status is set as selected. Partition setting can be selected by DIP switch or
command. Refer to the command description for the details.

Definition of download character( such as alpha numeric).
1. “s” indicates a number of bytes in a vertical direction and “a” is a number of dots in
horizontal direction.
2. “n” indicates the start character code, and “m” means the end character code. If only 1
character should be defined, then n = m.
3. Definable characters are from [20] h to [7E] h in ASCII code (95 characters).
4. “Dn” indicates the data to be defined. It indicates the “a” dots pattern from the left.
Remaining area on the right of a character is filled with spaces.
5. Once a download character is defined, it remains valid until the download character is
redefined, printer is initialized, reset signal is input, or the power is turned off.
