Loading the Roll paper
NOTE
Be sure to use paper rolls that meet the specifications. Do not use paper rolls that have the paper glued to the core because the printer cannot detect the paper end correctly.
Turn off power switch.
- Make sure that the printer is not receiving data; Otherwise, data may be lost.
- Open the paper roll cover by pushing down the cover open button.
- Remove the used paper roll core if there is one inside.
- Insert new paper roll as shown.
- Be sure to note the correct direction that the paper comes off the roll.
- Pull out a small amount of paper, as shown. Then, close the cover.
- Tear off the paper as shown.
CAUTION:
When the paper is jammed with the cutter, the top cover might be stuck. In this case, repeat power on and off several times.
If the top cover is still stuck, please follow the steps to release the papers from jamming.
- Make sure the printer is turned off.
- Take out DIP switch cover as shown.
- Turn screw with drivers to a direction until paper is released from the cutter.
Adjustment of paper width
- Please adjust the Paper Guide to fit to the paper width as the direction of the arrow.
- Tight the screw after adjusting the Paper Guide.
- Pull the edge of paper once the paper roll is installed correctly and close the Paper Cover.
Control panel and other functions
Control panel
You can control the basic paper feeding operations of the printer with the button on the control panel. The indicator lights help you to monitor the printer’s status.
Control Panel
Button
The button can be disabled by the ESC c 5 commands.
Press the FEED button once to advance paper one line. You can also hold down the FEED button to feed paper continuously.

The self-test result indicated whether the printer is operating properly. Also with this, user can check following options or status of the printer.
Control circuit
Printer mechanism
Printing quality
ROM version
Interface setting
This test is independent of any other equipment or software.
Running the self-test
- Make sure the printer is turned off and the printer cover is closed properly before performing the self-test.
- Turn the printer on holding the FEED button, then the self-test will start.
The self-test prints the printer setting value and then prints the following, and pauses.(Error LED On)
SELECT MODE BY BUTTON
1. ASCII PRINT
2. SELECT BAUDRATE MODE
3. HEXADUMP MODE - Press the FEED button consecutively (1~3)
1. ASCII PRINT (press the FEED button once) Printing test page constructed with ASCII code. 2. SELECT BAUDRATE MODE (press the FEED button twice) Set the speed of Serial Interface
(You can set the baudrate in this mode)3. HEXADUMP MODE (press the FEED button quad time) Printing the HEX value received from the interface Wait for 5~6 seconds if you want to exit. The printer performs a cutting when exiting this mode4
- The printer is ready to receive data after finishing the setting.
ASCII Print
ASCII PRINT is printing a test page constructed ASCII code. You can able to check the printer works properly with this The ASCII PRINT test automatically ends and cuts the paper after printing the following:
*** Completed ***
The printer is ready to receive data as soon as it completes the ASCII PRINT.
Select Baudrate Mode
After entering the BAUDRATE MODE, the list which can select the BPS will be printed. Similar like Self Test, you can press the FEED button to select a baud rate.
Once the input performs properly, the printer shows a result and store.
The printer is ready to receive data as soon as it completes the SELECT BAUDRATE MODE.
SELECT BAUDRATE BY BUTTON
- 9600bps
- 19200bps
- 38400bps
- 115200bps
Hexadecimal Dump
This feature allows experienced users to see exactly what data is coming to the printer. This can be useful in finding software problems.

To use the hex dump feature, follow these steps
- Please turn the printer off.
- Please turn the printer on while press down the “FEED” button.
- Press the FEED button three times when the Self Test is printed.
- Now printer had entered into Hexa dump mode.
- Run any software program that sends data to the printer. The printer prints ”Hexadecimal printing mode…” and then all the codes it receives in a two-column format.
The first column contains the hexadecimal codes and the second column gives the ASCII characters that correspond to the codes.
Hecadecimal Dump 1B 21 00 1B 26 02 40 40 .!..& . @ @
1B 25 01 1B 63 34 00 1B .%..c4 ..
41 42 43 44 45 46 47 48 ABCDEFGH
A period (.) is printed for each code that has no ASCII equivalent. - Turn off the printer.
- Turn on the printer.
Printer Cleaning
If the interior of the printer is dusty, printing quality can be lowered.
In this case, follow the instructions below to clean the printer.
NOTE
- Make sure to turn the printer power off prior to cleaning
- Regarding print head cleaning, as the print head is very hot during printing, turn off the printer power and wait approximately 10 minutes before starting.
- When cleaning the print head, take care not to touch the heated part of the print head. The print head is subject to be damaged by static electricity.
- Take care not to allow the print head to become scratched and /or damaged in any way.
- Use an applicator swab moistened with an alcohol solution to clean the print head and remove any dusts.
- Once the cleaning is completed, insert paper roll into the printer few minutes later and close the printer cover.
Preventing Overheating
To prevent the motor from overheating, continuous operation of the printer should be 1.5 m or less in print length. Set the pause time for 30 seconds or more than it.
