4. MAINTERNANCE & TROUBLESHOOTING
4-1. INSTALLING OR REPLACING PAPER ROLL
CAUTION: Make sure that paper rolls meets printer’s specifi cation. Do not use paper rolls that have one
end glued to the core. This causes excessive load on the paper feed.
1: Make sure that the printer is not printing or receiving data, and open the
printer cover by sliding the cover open knob. Unroll 10 to 15 cm of the
paper as shown.
2: Insert the paper roll as shown.
3: Pull out 10 to 15 cm of paper and close the printer cover as shown.
Tear off the excess paper on the cutter edge.
4-2. ADJUSTING THE PAPER NEAR END SENSOR
A sensor detects when the paper roll is running out. Due to variation in the width of paper roll cores, it is
diffi cult to measure the exact length of the paper left on the roll when the detector is triggered. The factory
setting is based on a paper roll core with an outside diameter of 18 mm and an inside diameter of 12 mm. If
you use a paper roll with different widths, adjust the setting as described below.
1: Open the printer cover and remove the paper roll.
2: Loosen the adjusting screw and move the tab to fit the core of the paper roll.
3: Tighten the adjusting screw.
4: Replace the paper roll and close the printer cover.

4-3. PAPER JAM
CAUTION : Do not touch the printer head because they are very hot after continuous printing. Do not
attempt to clear a paper jam until the printer cools down.
1: Turn the printer off and slide the cover open knob.
2: Remove the jammed paper and replace the paper roll.
If the printer cover can’t be opened after a paper jam, follow the procedure below.
1. Push down and slide to remove the Automatic Paper Cutter Cover.
2. Pull up the clear fi lm, and slowly turn the screw inside counter-clockwise
until the cutter edge reaches home position.
3. Push down and slide to close the Automatic Paper Cutter Cover.
4. Now, the printer cover should open easily.
Remove the paper jam and replace the paper roll.

4-4. TROUBLESHOOTING
Error Contents Causes / Points to check Solutions
Can’t turn the printer ON Is the power switch turned ON? Turn the power switch ON
Is the connector on the power
adapter properly connected?
Connect the connector firmly
Does the printer reset when you turn
the power switch ON?
If it does, something is wrong with the
operation Panel.
Does the LED on the adapter light up
when connected to the wall?
If it doesn’t, check the connection of the
Power Supply cord. If the connection
is OK, something is wrong with the
adapter.
Other Something may be wrong with the
power switch parts or with the main
board.
The ON LINE indicator
doesn’t light up
Is the ERROR Indicator ON? If it is, see “the ERROR Indicator is ON”
Press the ON LINE button If the ON LINE Indicator turns on, it’s
normal
The ERROR Indicator is
ON
Check if the printer is out of paper If paper is out, replace with a new roll
The cover doesn’t open even if
you slide the cover open knob
The Automatic Paper Cutter may be
locked. 3.3, “Printer Jam”
The printer cover doesn’t close
completely
Open the cover by sliding the cover
open knob, and close it again by
pushing at center of the cover.
The ERROR indicator
doesn’t light up while
paper is exhausted
(The Printer Cover is close)
The ON LINE Indicator lights up by
using the ON LINE button
Something is wrong with the paper
sensor of the main board inside the
printer
Other Something is wrong with the operating
panel
Can’t print the self test The ON LINE indicator is not ON See “ON LINE Indicator doesn’t light up
Printing causes the paper to feed Something is wrong internally or with
the printer head.
Printing cannot be done
by the commands from
the HOST or printing
garbled
Check print capability by running the
Self-Test
If printing fails, see “Can’t Print”
Is the Connector of Interface firmly
connected with screws?
Seat the connector firmly and tighten
the screws
Check the setting of DIP switch Refer Appendix and set the switches
correctly, then power cycle the printer
The drawer Kick doesn’t
work
Is the drawer kick connected
properly?
Re-plug in the cable. You should hear
or feel a click if the proper connection is
made.
Is Y-cable connected in reverse
order?
Check the Y-cable and verify it is
connected in the correct order.
Other Something may be wrong with the main
board inside the printer.
The ERROR Indication
and ON LINE Indication
flash on and off
alternately
Check the setting of DIP Switch Refer to Appendix. Turn the printer off,
make any necessary changes, then
turn the printer on

Self Print (Japanese CG)
4-5. SELF TEST
Use the self test to check that your printer is operating properly. It checks the control circuits, printer
mechanisms, print quality, and displays the firmware version and DIP switch settings.
1: Make sure that the printer cover is closed properly and turn the power off.
2: While holding down the FEED button, turn the printer on and continue holding down the FEED button
until the self test starts.
3: The self test will end automatically and detach the self test print out.
Cut
Printing quality is confirmed.

The number changes according to the version.
Confirm that the font is JAPANESE.
DIPSW setting appears differently if the setting
at the factory default is different.
Board defect if "not found" appears.
Write defect if "OK" does not appear.
