2. Setting Up the Printer
2.1 Unpacking
Your printer box should contain the following items. If any items are damaged or missing, please contact your dealer for assistance.
Included Items: The Printer, CD, Roll Paper, Adaptor (Option), USB Cable (option).
2.2 Connecting the Cables
All cables connect to the connector panel on the back of the printer. Before connecting any cables, ensure both the printer and the computer are turned off.
2.2.1 Interface Connector
25-Pin Serial Interface:
| Pin | Signal | I/O | Description |
|---|---|---|---|
| 2 | TxD | Output | Printer transmit data line RS-232C level |
| 3 | RxD | Input | Printer receive data line RS-232C level |
| 4, 20 | DTR | Output | Printer handshake to host line RS-232C level |
| 6 | DSR | Input | Data Send Ready |
| 1, 7 | GND | - | System Ground |
USB Interface:
| Pin | Signal | I/O | Description |
|---|---|---|---|
| 1 | +5V | - | +5V |
| 2 | DATA- | - | Printer transmit data line |
| 3 | DATA+ | - | Printer transmit data line |
| 4 | GND | - | System Ground |
2.2.2 Cash Drawer Connector
The printer supports two cash drawers via a 6-pin RJ-11 modular connector. The driver can supply a maximum current of 1.0A for 510ms or less when not printing.
| PIN | SIGNAL | DESCRIPTION |
|---|---|---|
| 1 | Signal GND | - |
| 2 | Drawer kick-out drive signal 1 | Output |
| 3 | Drawer open/close signal | Input |
| 4 | +24V | - |
| 5 | Drawer kick-out drive signal 2 | Output |
| 6 | Signal GND | - |
NOTE: Cash drawers 1 and 2 are internally connected. As the printer cannot distinguish between them, it is recommended to use only one cash drawer.
2.3 Loading the Roll Paper
Notes: Use paper rolls that meet specifications. Avoid rolls with paper glued to the core, as this can prevent correct paper end detection.
- Turn off the power switch.
- Ensure the printer is not receiving data to prevent data loss.
- Open the printer cover by pushing the 'COVER OPEN PUSH BUTTON'.
- Remove any used paper roll core.
- Insert the new paper roll, ensuring the paper comes off in the correct direction (indicated by a circular diagram showing 'O' for correct and 'X' for incorrect).
- Pull out a small amount of paper.
- Close the printer cover.
- Tear off the paper.
3. Control Panel and Other Functions
3.1 Control Panel
The control panel allows basic paper feeding operations and monitoring of printer status via indicator lights.
Control Panel Components: POWER, ERROR, PAPER indicators, and a FEED button.
FEED Button: Press once to advance paper by one line. Holding the button down feeds paper continuously. This button can be disabled via the ESC c 5 command.
3.2 Error Indicators
The two LED indicators on the top cover signal printer status:
| STATUS | PAPER RED | ERROR RED | POWER GREEN | REMARKS |
|---|---|---|---|---|
| Power off | OFF | OFF | OFF | No power supplied to the printer. |
| Power on | OFF | OFF | ON | Normal power supplied. |
| On line | OFF | OFF | ON | Normal error-free mode. |
| Cover open | OFF | ON | ON | Close the cover. |
| Paper empty | ON | ON | ON | Insert new paper roll. |
| Test mode | OFF | OFF | ON | Error LED ignored. |
Cutter Jam Troubleshooting: If the cutter is jammed, follow these steps: 1. Turn off the power. 2. Open the cover using the 'COVER OPEN PUSH BUTTON'. Be cautious of the cutter blade. 3. Turn the power back on; the cutter will reset automatically. 4. Close the cover.
4. Self Test
The self-test verifies printer operation and allows checking of control circuit, printer mechanism, printing quality, ROM version, and interface settings. It operates independently of other equipment.
Running the Self Test
- Ensure the printer is turned off and the cover is closed.
- Turn the printer on while holding the FEED button. The self-test will begin, printing settings and then pausing (Error LED ON).
- The printer will prompt to select a mode by pressing the FEED button:
- 1. ASCII PRINT (prints a test page with ASCII code)
- 2. SELECT BAUDRATE MODE (sets the Serial Interface speed)
- 3. HEXADUMP MODE (prints received HEX values)
- 4. SELECT ERROR BEEP MODE (enables/disables printer error beeps)
- Press the FEED button consecutively (1-4 times) to select the desired mode.
Wait 5-6 seconds to exit the mode; the printer will cut the paper. The printer is ready for data input after setting completion.
5. ASCII Print
This function prints a test page using ASCII code to verify printer functionality. The test automatically ends and cuts the paper upon completion, displaying "*** Completed ***". The printer is then ready to receive data.
6. Select Baudrate Mode
After entering this mode, a list of Baud Per Second (BPS) options will be displayed. Use the FEED button to select the desired baud rate. The printer stores the selection and is ready to receive data.
Baudrate Options: 1. 9600bps, 2. 19200bps, 3. 38400bps, 4. 115200bps.
7. Hexadecimal Dump
This feature allows experienced users to view raw data sent to the printer, aiding in software problem diagnosis. The printer outputs commands and data in hexadecimal format with a guide section.
Using Hexadecimal Dump:
- Turn the printer off.
- Turn the printer on while holding the FEED button.
- Press the FEED button three times after the Self Test begins.
- The printer enters Hexa dump mode.
- Run any software that sends data to the printer. The printer will display "Hexadecimal printing mode..." followed by codes in a two-column format: hexadecimal codes and their corresponding ASCII characters. A period (.) indicates no ASCII equivalent.
- Turn the printer off and then on again to exit.
8. Select Error Beep Mode
This function controls the buzzer status for printer errors like paper out or cover open. The setup menu will print, and the FEED button can be pressed once or twice to select BEEP MODE ON or BEEP MODE OFF.
9. Peripherals Connection
The printer supports communication with other devices via Bluetooth, Wi-Fi (802.11a/b/g/n), and cable connections.
9-1. Bluetooth Connection (Optional)
Connect to devices with Bluetooth capacity (PDAs, PCs, etc.) using the device's built-in Bluetooth connection function. Refer to the Bluetooth Manual for details.
9-2. Wi-Fi (802.11a/b/g/n) Connection (Optional)

10. Printer Cleaning
Dusty interiors can reduce printing quality. Follow these instructions for cleaning:
Notes:
- Turn off the printer power before cleaning.
- Allow the print head to cool for approximately 10 minutes before cleaning, as it gets very hot during printing.
- When cleaning the print head, avoid touching the heated part to prevent damage from static electricity.
- Do not scratch or damage the print head.
- Use an applicator swab moistened with an alcohol solution to clean the print head and remove dust.
- After cleaning, insert paper and close the printer cover after a few minutes.
Preventing Overheating: To prevent motor overheating, limit continuous printing to 1.5 meters or less. Set a pause time of 30 seconds or more between print jobs.
