WARNING
• 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.
• During and immediately after printing, the area around the thermal head is very hot. Do not
touch it, as you could be burned.
CAUTION
• Do not operate the cover open lever while pressing on the printer cover with your hand.
• Donotpullthecoveropenleverandopentheprintercoverwhenprintingisinprogressorwhen
the auto cutter is operating.
• Do not pull out paper while the printer cover is closed.
• The heating element and the driver IC of the thermal head are easily damaged. Do not touch
them with metal objects, sandpaper, etc.
• 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.
• There is a risk of damage to the driver IC of the thermal head from static electricity. Never
directly touch the IC.
• 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.
• Do not operate the printer if there is moisture on the front surface of the head from
condensation, etc.

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 auto cutter models, it means that the auto cutter is not
at the home position. In this case, return the auto cutter to the home position by following
the instructions provided in section 7-3. Then open the printer cover after the paper jam has
been removed.
(3) Remove the jammed paper.
CAUTION
Take care not to damage the printer when removing the jammed paper.
Since it is easy to damage the thermal head in particular, take care not to touch it.
(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.

(3) Remove any jammed paper.
Note: Be careful not to damage the printer while removing any jammed paper.
Since the thermal print head is particularly sensitive, be sure not to touch it.

(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.

8. 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.
8-1. Cleaning the Thermal Head
To remove blackish dust collected on the surface of the thermal head, wipe it with Isopropyl
alcohol (IPA).
Note: The thermal head is easy to damage, so clean it gently with a soft cloth. Take sufficient
care not to scratch it when cleaning it.
8-2. Cleaning the Paper Holder
Use a soft cloth to remove paper dust from the paper holder and paper transport section.

Notes:
• When using a printer power supply other than the optional AC adapter (PS60A-24A
series), be sure that the following cautions are observed.
• Use a power supply of DC 24 V 5% and more than 2.0A(5.0ALoad 10 sec. Min.) with
SELV output and LPS or Class 2 output approved by IEC60950.
• Be careful about installing the printer in an area where there is noise. Take the appropriate
measures to protect against electrostatic AC line noise, etc.

10-6. Reliability
1) Life
Mechanical: 20 million lines
Head:
100 million pulses, 100 km ( 15% max. average head resistance
fluctuation)
For 2-color printing, 50 million pulses, 50 km ( 15% max.
average head resistance fluctuation)
Auto cutter: 1millioncuttings(providedthepaperthicknessisbetween65and
85 µm)
<Conditions>
Average printing ratio:
12.5%
Recommended thermal paper: 65 µm
2) MCBF: 60 million lines
The Mean Cycle Between Failure (MCBF) is defined to be the overall failure cycle, which
includes random or wear failures that occur until the printer reaches its mechanical life of
20 million lines.
* As the mechanical remains at 20 million lines, the MCBF of 60 million lines does not
indicate its useful life.
3) Auto Cutter (Life)
1 million cuttings (provided the paper thickness is between 65 and 85 µm)
* All the reliability values indicated above are based on the use of the recommended thermal
paper. No reliability can be guaranteed for the use of non-recommended thermal paper.
