Caution Symbol

This symbol is placed near the thermal head to indicate that it may be hot.

Never touch the thermal head immediately after the printer has been used.

Let the thermal head cool for a few minutes before touching it.

This symbol is placed near the thermal head to indicate that it is easily damaged.

Observe the precautions for handling electrostatic sensitive devices.

WARNING

1) Do not touch the cutter blade.

• There is a cutter inside the paper outlet slot. Not only should you not put your hand in the
paper outlet slot while printing is in progress, never put your hand into the outlet even
when printing is not in progress.

• The printer

cover can be opened when replacing the paper. However, since the cutter
blade is on the inside of the printer cover, be careful not to place your face or hands too
close to the cutter blade.

2) During and

immediately after printing, the area around the thermal head is very hot. Do

not touch it, as you could be burned.

CAUTION

1) Do not operate the cover open lever while pressing on the printer cover with your hand.

2) Do not push the cover open lever and open the printer cover when printing is in progress
or when the auto cutter is operating.

3) Do not push out paper while the printer cover is closed.

4)

The heating element and the driver IC of the thermal head are easily damaged. Do not

touch them with metal objects, sandpaper, etc.

5) Printing quality

may suffer if the thermal head heating element becomes soiled by being

touched with your hands. Do not touch the thermal head heating element.

6) There

is a risk of damage to the driver IC of the thermal head from static electricity. Never

directly touch the IC.

7) The printing

quality and working life of the thermal head cannot be guaranteed if any paper
other than that recommended is used. In particular, paper containing [Na+, K+, C1-] may
drastically reduce the working life of the thermal head. Please exercise caution.

8) Do not

operate the printer if there is moisture on the front surface of the head from con-

densation, etc.

9) A printed

piece of thermal paper may become electrically charged. If the printer is placed
vertically or mounted on a wall, the cut piece of paper may stick to the printer, instead of
falling. Beware that this could cause a problem if you use a stacker that stores the pieces
of paper that fall freely.

10)

Do not

change the paper width during use. The thermal printing head, rubber roller, and
cutter wear differently according to the paper width. This can cause the printing or cutter
movement to malfunction.

11) Do not transport the printer with its co

ver open and holding it by the cover.

12) Do not forcibly pull on the interface cable, power cable, or cash drawer cable that is con­nected. To detach a connector, make sure to grasp it at the connector portion, without ap­plying excessive stress on the connector at the printer.

– 13 –

Notes on Using the Auto Cutter

1) To print after a cut, feed 1 mm (8-dot line) or more of paper.

2) If the cutter is not in its home position after an error, first eliminate the cause of the error;
then, turn the power back ON.

3) A mar

gin of 5 mm or more is recommended from the end of the printed area to the cutting

position.

4) Do not attempt to remo

ve the paper during a cut, as this can cause a paper jam.

8-3. 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.

(4) If the cutter is locked, insert a Philips screwdriver

into the Philips screw hole on the side of the cutter,
and turn it in the direction of the arrow shown on
the right, in order to return the cutter to its normal
position.

(5)

Open the

printer cover, remove any jammed paper,

and then reinstall the paper roll.

(6) Install the

front cover, and then set the power

switch to ON.

(1) Set the

power switch to OFF to turn off the print-

er.

(2)

Remov

e the front cover to reveal the auto cutter.

(3) Remove any jammed paper.

Note: Be careful not to damage the printer while

removing an

y jammed paper.

Since the thermal

print head is particularly

sensitive, be sure not to touch it.

9. Periodical Cleaning

Printed characters may become partially unclear due to accumulated paper dust and dirt. To
prevent such a problem, paper dust collected in the paper holder and paper transport section
and on the surface of the thermal head must be removed periodically.
Such cleaning is recommended to be carried out once six month or one million lines.

9-1. Cleaning the Thermal Head

To remove the dark paper dust that has accumulated on the thermal head surface, wipe it clean
with cotton swab (or soft cloth) dipped in alcohol (ethanol, methanol, or isopropyl alcohol).

Note 1: The thermal head

is easily damaged, so clean it with a soft cloth, taking care not

to scratch it.

Note 2: Do not attempt to clean the thermal head immediately after printing, when the

thermal head is hot.

Note 3: Bew

are of the risk of damaging the thermal head as a result of static electricity

that may be created during cleaning.

Note 4: Turn the po

wer ON only after the alcohol has dried completely.

9-2. Cleaning the Rubber Roller

Use a dry, soft cloth to wipe off the dust that may have accumulated on the rubber roller.
Rotate the platen to clean the entire surface.

9-3. Cleaning the Paper Holder and the Surrounding Area

Clean the paper holder of debris, dust, paper particles, glue, etc. that may have accumulated.
