Warning - U.S.
This equipment has been tested and found to comply with the limits for a Class A digital
device pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference when the equipment is operated in a
commercial environment. This equipment generates uses, and can radiate radio frequency
energy and if not installed and used according to the instruction manual, may cause
harmful interference to radio communications. Operation of this equipment in a residential
area is likely to cause harmful interference in which case the user will be required to correct
the interference at his own expense.
Notice - Canada
This Apparatus complies with class “A” limits for radio interference as specified in the
Canadian department of communications radio interference regulations.
Get appareil est conforme aux normes class “A” d’interference radio tel que specifier par
ministre canadien des communications dans les reglements d’interference radio.
Caution
Some semiconductor devices are easily damaged by static electricity. You should turn the
printer “OFF”, before you connect or disconnect cables. This will help protect the printer
against static electricity. If the printer is damaged by the static electricity, you should turn
the printer OFF, and refer to your local service provider.

6)
. Tear off the paper as shown, if necessary.
10
. Insert the end of the roll paper into the groove on the Roller-Pulley, warp the paper
7)
around it two or three times and load the Roller-Pulley onto the groove of the Case.
8). Push the auto-cutter cover as shown below and close the printer cover.
NOTE : Push upper face of the au t o cut ter cover for completely locking of it .
9)
. When the ERROR light is on and PAPER OUT light blinks, please press the FEED
button. After that, the printer is ready for printing.

Chapter 4. Setting the DIP switches
The DIP switches are located on the bottom of the printer. The DIP switches are used to
set the printer to perform various functions. Follow these steps w hen changing DIP switch
settings :
1. Turn the printer power switch off.
2. Turn the printer over and remove the dip switch cover.
Move the DIP switches using tweezers or another narrow-ended tool.
3.
Switches are on when up and off when down in the figure below.
The new setting takes effect when you turn on the printer.
4.
NOTE : Always change DIP switch settings when the printer is turned off.

Chapter 5. Hexadecimal Dumping
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 hexadecimal dump
function, the printer prints all commands and data in hexadecimal format along with a
guide section to help you find specific commands.
To use the hexadecimal dump function, follow these steps:
1. After you make sure that the printer is off.
2. Set DIP switch 2-2 On.
3. Turn on the printer, then the printer enters the hexadecimal dump mode.
4. Run any software program that sends data to the printer. The printer will print
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.
1B 21 00 1B 26 02 40 40 . ! . . & . @ @
02 0D 1B 44 0A 14 1E 28 . . . D . . . . (
00 01 0A 41 0D 42 0A 43 . . . A . B . C
A period(.) is printed for each code that no ASCII equivalent.
During the hex dump, all commands except DLE EOT and DLE ENQ are
disabled.
Insufficient print data to fill the last line can be printed by pressing the feed
button.
5. When the printing finishes, turn off the printer, and then change DIP switch 2-2
OFF.
6. Turn on the printer and then the hexadecimal mode is off.
15
Chapter 6. The self test
The self-test checks whether the printer has any problems. If the printer does not function
properly, contact your dealer.
The printer is ready to receive data when it completes the self-test.
1. Make sure paper roll has been installed properly.
2. Turn on the power while holding down the FEED button. The self-test
begins.
3. The self-test prints the current printer status, which provides the control
ROM version and the DIP switch setting.
4. After printing the current printer status, s elf-test printing will print the
following, and pause (The PAPER LED light blinks).
Self-test printing.
Please press the FEED button
5. Press the FEED button to continue printing. The printer prints a pattern
using the built-in character set.
6. The self-test automatically ends after printing the following.
** Character Test Completed **
16
Chapter 7. Code Table
The following pages show the character code tables. To find the character corresponding to
a hexadecimal number, count across the top of the table for the left digit and count down
the left column of the table for the right digit. For example, 4A = J.

3) Remove the ribbon cassette.
4) Loosen the manual screw.
5) Remove the head cover.
CAUTION: The printer head becomes very hot during printing.
Allow it to be cool before you reach into the printer.
33
Move the print head carriage to the reverse direction of paper jam. By pushing
6)
on the side of the print head as shown in the illustration.
7) Remove the jammed paper by rotating the paper-feed knob.
8) Replace the head cover and secure it with screw.
9) Replace the ribbon cassette and roll paper, then close the printer cover.
