2-3. Loading the Roll Paper
Notes: 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)
1. Make sure that the printer is not receiving data; Otherwise, data may be lost.
2. Open the paper roll cover by pushing down the cover-open button.
3. Remove the used paper roll core if there is one inside.
4. Insert new paper roll as shown.

2-4. Dip Switch Setting
The printer is set up at the factory to be appropriate for almost all users. On the other hand,
offers some more settings for users with special requirements.
It has DIP switches that allow you to change communication setting, such as handshaking and
parity check, as well as print density.
Your printer has two sets of DIP switches. The functions of the switches are shown in the
following tables.
♦Note : Power off. And open the cover of Dip Switch and change setting.
(*1) The detecting function of [Paper Low] is an option.
Please set Dip Switch (2-6) [OFF] if you don't need any option.
If Dip Switch is [ON] without any special option purpose.
Printer detects [Paper is Low] and it could cause error.

♣CAUTION:
Turn off the printer while removing the DIP switch cover to prevent an electric short, which can
damage the printer.
1. Make sure the printer is turned off.
2. Remove the screw from the DIP switch cover. Then, take off the DIP switch cover as shown in
the illustration below.
3. Set the switches using a pointed tool, such as tweezers or a small screwdriver.
4. Replace the DIP switch cover. Then, secure it with the screw.
The new settings take effect when you turn on the printer.

♣CAUTION:
When the paper is jammed with 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.
1. Make sure the printer is turned off.
2. Remove the screw from the DIP switch cover. Then, take off the DIP switch cover as shown in
the illustration below.
3. Turn screw with drivers to a direction until paper is released from the cutter.

4. Self Test
The self-test lets you know if your printer is operating properly. It checks the control circuits,
printer mechanisms, print quality, ROM version and DIP switch settings.
This test is independent of any other equipment or software.
Running the self test
1. Make sure the printer is turned off and the printer cover is closed properly.
2. While holding down the FEED button, turn on the printer using the switch on the front of the
printer to begin the self-test. The Self Test prints the printer settings and then prints the following,
Cuts the paper, and pauses. (Error LED On)
Self test printing
Please press the PAPER FEED button.
3. Press the FEED button to continue printing.
The printer prints a pattern using the built-in character set.
4. The self 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 self-test.

5. 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.
When you turn on the hex dump functions, the printer prints all commands and other data in
hexadecimal format along with a guide section to help you find specific commands.
To use the hex dump feature, follow these steps:
1. After you make sure that the printer is off and Dip s/w 1-2 is ON, turn on the printer.
2. Run any software program that sends data to the printer. The printer prints “Hexadecimal
Dump” 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 ASC
codes.
