2-2. Choosing a place for the printer
Before actually unpacking the printer, you should take a few minutes to think about where
you plan to use it. Remember the following points when doing this.
3 Choose a firm, level surface where the printer will not be exposed to vibration.
3 The power outlet you plan to connect to for power should be nearby and unobstructed.
3 Make sure that the printer is close enough to your host computer for you to connect
the two.
3 Make sure that the printer is not exposed to direct sunlight.
3 Make sure that the printer is well away from heaters and other sources of extreme
heat.
3 Make sure that the surrounding area is clean, dry, and free of dust.
3 Make sure that the printer is connected to a reliable power outlet. It should not be on
the same electric circuit as copiers, refrigerators, or other appliances that cause power
spikes.
3 Make sure that the room where you are using the printer is not too humid.
WARNING
3 Shut down your equipment immediately if it produces smoke, a strange odor, or unu-
sual noise. Immediately unplug the equipment and contact your dealer for advice.
3 Never attempt to repair this product yourself. Improper repair work can be dangerous.

2-3. Handling Care
1. Be careful not to drop paper clips, pins or other foreign matter into the unit as these cause
the printer to malfunction.
2. Do not attempt to print when either paper or ribbon cartridge is not located in the printer,
otherwise the print head can be damaged.
3. Do not open the cover while printing.
4. Do not touch the print head immediately after printing as it gets very hot.
5. Use only roll paper that is not glued to the core.
6. When the paper end mark appears on the paper, replace the roll paper before it runs out.
2-4. Maintenance
Essentially, your printer is a robust piece of equipment, but should be treated with a modicum
of care in order to avoid malfunctions. For example:
1. Keep your printer in a “comfortable” environment. Roughly speaking, if you feel comfort-
able, then the environment is suitable for your printer.
2. Do not subject the printer to physical shocks or excessive vibration.
3. Avoid over-dusty environments. Dust is the enemy of all precision mechanical devices.
4. To clean the exterior of the printer, use a cloth barely dampened with either water with a
little detergent or a little alcohol, but do not allow any liquid to fall inside the printer.
5. The interior of the printer may be cleaned with a small cleaner or a compressed-air aerosol
(sold for this purpose). When performing this operation, be sure not to bend or damage any
cable connections or electronic components.

6-4-2. Adjusting the Dot Alignment Mode
You may never have to use the procedure described in this section, but after you have been using
your printer for some time you may find that the dots of some graphics do not align correctly.
For example, what should look like:
may come out looking like one of the following:
This is caused when mechanical parts of the printer get out of alignment. This happens only
rarely and you may never experience it at all throughout the life of the printer. If you do have
problems, use the following procedure to correct it.
(1) Enter the Dot Alignment Adjust Mode according to the procedure described in Section 6-4.
(2) After entering the Dot Alignment Adjust Mode, a printout of the adjustment patterns
similar to the printout below will be printed. The asterisk indicates the current adjustment
pattern.
– 27 –
(3) To adjust, use the FEED switch to select the adjustment pattern from the printout with the
smallest gap between the first printing pass and the return printing pass. Press the FEED
switch once to specify the first adjustment pattern, twice to specify the second adjustment
pattern, and so on up to seven times to specify the seventh adjustment pattern.
At the number that you want to specify, press and hold (2 seconds) the FEED switch until
the long buzzer sounds. This will specify the setting value. (For example, if you want to
select the eighth pattern from the top, press the FEED switch seven times. Then, at the eighth
pattern, press and hold (2 seconds) the FEED switch until the long buzzer sounds.)
There are only twenty three adjustment patterns. The buzzer will sound each time the FEED
switch is pressed. However, if you press the FEED switch more than twenty three times, a
warning alert will sound.
(4) If there is no matching pattern among the adjustment patterns, perform the “Backward” or
“Forward” operation described below in order to print a printing pattern in which the dot
alignment settings are changed. Then, repeat step (3).
Backward:
Press and hold the FEED switch for 2 to 4 seconds. The buzzer will beep, and the
printer will print a pattern in which the forward is adjusted more leftward of the pres-
ently indicated pattern and the backward is adjusted more rightward.
Forward:
Press and hold the FEED switch for 4 seconds or longer. The buzzer will beep-beep,
and the printer will print a pattern in which the forward is adjusted more rightward
of the presently indicated pattern and the backward is adjusted more leftward.
(5) After selecting the adjustment pattern, the setting value is stored in the non-volatile memory.
A printout similar to the one below with the selected adjustment pattern highlighted and
the message “Adjust Completed!” will be printed.
Note: Before the printout is printed, the setting value is stored in the non-volatile memory
of the printer after the adjustment pattern has been selected and the long buzzer
sounds. During this period, do not set the power switch to off. If this power switch
is set to off when the setting value is being stored in the non-volatile memory, the
setting value for the adjustment pattern and all of the memory switch settings will
be reset.
(6) The long buzzer sounds once more and the setting value is automatically set.
The adjusting the dot alignment mode is complete.

7. Preventing and Clearing Paper Jams
7-1. Preventing Paper Jams
The paper should not be touched during ejection and before it is cut.
Pressing or pulling the paper during ejection may cause a paper jam, paper cutting failure or
line feed failure.
7-2. Removing Paper Jam
If a paper jam occurs, clear it as described below.
(1) Set the power switch to off to turn off power to the printer.
(2) Push the cover open lever, and open the printer cover.
If the printer cover will not open on an auto cutter model, it means that the auto cutter is
not in the home position (or locked). In this case, return the auto cutter to the home posi-
tion by following the instructions provided in Section 7-3.
(3) Remove the jammed paper.
CAUTION
Take care not to damage the printer when removing the jammed paper.
(4) Position the roll paper straight and close the printer cover gently.
Note 1: Make sure that the paper is positioned straight. If the printer cover is closed with
the paper skewed, a paper jam may result.
Note 2: Lock the printer cover by pressing down on the sides. Do not try to close it by
pressing down on the center. The cover may not lock properly.
(5) Set the power switch to on to turn on power to the printer. Make sure that the ERROR LED
is not lit.
Note: While the ERROR LED is lit, the printer will not accept any commands such as
the print command, so make sure that the printer cover is locked properly.
– 31 –
7-3. Releasing a Locked Cutter (Auto Cutter Mode only)
If the auto cutter locks up or fails to cut the paper, follow the steps below.
WARNING
Since working on the cutter may be dangerous, be sure to turn off the printer first.
(1) Set the power switch to OFF to turn off the printer.
(2) Ordinarily, a locked cutter will recover automati-
cally by closing all the covers and turning the power
back ON.
Recovery means that the locked cutter has been
released, so steps (3) and thereafter are unneces-
sary. If the cutter has not recovered, proceed to
step (3).
(3) Pull the cover open lever towards you, and open
the printer cover. The printer cover may not open
due to the cutter being locked. In this case, follow
steps (4) and (5) to first open the front cover and
remove the tear bar. If the printer cover opens,
proceed to step (6).
Note: Since the print head is hot immediately
after printing, be sure not to touch it. On
an auto cutter model, a paper cutter is
located at the paper outlet slot. Be careful
not to touch the cutter blade.
(4) Open the front cover by holding the finger grips
on both ends of the cover and lifting it up.
(5) Remove the two screws to remove the tear bar.

(6) After you have opened the printer cover, remove the four screws to remove the printer cover
and reveal the cutter.
(7) If the cutter is locked, insert a Phillips screwdriver into the Phillips screw hole on the side
of the cutter, and turn it in the direction of the arrow shown below, in order to return the
cutter to its normal position.
(8) Reinstall the printer cover by tightening its screws.
