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.

Self Test

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.

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.
