OUTLINE
(1) Scope of this document
This document applies to the EU-m30 and bezel option OT-BU30.
(2) Product safety precautions
1) Do not allow a voltage that exceeds the absolute maximum rating to be applied to the power connector.
If the applied voltage exceeds the absolute maximum rating, excess current may flow, causing thermal damage
to components.
Absolute maximum rating
Articles Rating Units
Circuit input power supply voltage 26.4 V
Storage temperature See 1.13 Environmental Conditions (2)
Storage environment.
Storage humidity
2) Use the product within the range of operating conditions shown in the table below.

3) Do not create short circuits between connector terminals in the printer unit.
Do not create short circuits between power connector terminals.
A short circuit to a low-impedance power supply can create excess current, causing thermal damage to
components.
4) During transport and storage, properly protect printer unit exterior (exposed) circuit boards and electronic
components with conductive sponges, aluminum foil, and such.
5) Do not drop clips and other conductive materials onto the printer unit's circuit board.
Short circuits between component connectors (terminals) can create excess current, causing thermal damage
to components.
6) Use only the cables indicated in this document. Also, use only the wiring indicated in this document.
Wiring done incorrectly can lead to a failure, fire, explosion, or other accident.
7) Do not disassemble or modify. Such actions can lead to injury or electric shock.
8) During operation, do not directly touch gears or other moving parts. You can get cut or otherwise injured.
9) Do not install in an unstable location (such as on an unsteady pedestal or sloping area). The product can
fall and you can get injured.
10) Do not install in a damp or dusty location. Also, ensure that the product is not exposed to water droplets.
Failure to do so may result in product failure, fire, or electric shock.
11) If the product will not be used for a long period, be sure to turn off the power to the printer unit for safety.

1GENERAL SPECIFICATIONS
1.1 Print Specifications
(1) Print speed
The maximum is 100 mm/s {3.94"/s} when printing ladder bar codes, 2-dimensional symbols, or multi-tone
graphics.
The print speed changes automatically depending on the voltage applied to the printer and the condition of the
head temperature.
Maximum print speed may not be achieved depending on the data transmission conditions and the combination
of commands.
If the print speed fluctuates or intermittent printing occurs due to the data transmission conditions, printing
may be shaded or white lines may occur.
(2) Multi-tone graphics printing and limitations
Multi-tone graphics printing is possible (up to 16 tones when using our specified paper).
Multi-tone printing is not supported in Page mode.
Voids (white spaces) may appear depending on the paper type (uneven application of chromogenic coating).
It may not be possible to recreate an original image because a certain density level cannot be achieved due to the
following causes:
Environmental temperature, power supply and voltage
Paper type (chromogenic characteristics)
Paper variations, such as variations among manufacturing lots
Printing pattern (effect of heat accumulation of the print head or of voltage drop/speed change due to high
duty)
For multi-tone printing, the preservative quality of materials printed using multi-tone printing decreases in
direct relationship with the lighter the printing. Accordingly, do not use multi-tone printing when preservative
quality is required.
Reading quality of bar codes/2-dimensional symbols in multi-tone graphics printing is not guaranteed.
1.2 Character Specifications
Can be changed via the software settings.
For details, see 3.8.3 Software setting mode.
1.3 Autocutter
The cut paper may be pulled at the cut edge when it is removed, causing reduced printing pitch for the first line
of the next receipt.
To prevent dot displacement, after cutting, feed the paper approximately 1 mm {16/406"} or more before the first
line of printing. This operation can be enabled by enabling the pre-feed before next print, or by setting the top
margin specification via backfeed to 8.5 to 2 mm.
For the setting method, see 3.5.2. Software setting.
When issuing paper whose vertical length is short, ensure at least 20 mm.

7
1.4 Paper Sensor
(1) Function
Detects whether paper is present in the paper path.
(2) Method
Microswitch
1.5 Roll Paper Supply Device
Use roll paper that is not deformed, and ensure there is no slack when setting.
(1) Function
Supplies paper with a width of 80 mm {3.15"} or 58 mm {2.28"}
(2) Method
Drop-in roll paper

(3) Print density adjustment depending on the specified original paper
In order to ensure optimal print quality and reliability, we recommend using the print density settings in the
table below.
The initial setting is 100% print density.
The print density can be changed using customized values.
When the print density setting is too dark, the print speed tends to drop.
When the print density setting is too dark, paper dust sticks to the print head surface, often resulting in faded
print.

(4) Notes on preprinting
Preprinted thermal paper may cause faulty printing and decreased print density due to the thermal head sticking
to the recording surface. Therefore, it is preferable to avoid using preprinted thermal paper.
If using preprinted thermal paper, make sure in advance that the conditions recommended by the original paper
manufacturing company (type of ink, print conditions, etc.) are met, and that there is no faulty printing or
decreased print density in the actual usage environment.

Note:
Printing with this product is assumed to be receipts or the equivalent. If printing is continuously performed
with a high print ratio, the overcurrent limitation may be operated. Therefore, the printing length must not
exceed 20mm {0.79"} when printing with 100% print ratio.
(3) AC power consumption (AC100 to 230 V / 50 to 60 Hz)
EU-m30
Operating: Approx. 24.2 W
Standby: Approx. 0.8 W
*Average power under operating conditions. Depends on use conditions and model.

1.12 Reliability
(1) Life
Printer mechanism: 17 million lines (Repeating 10 line-printing + 5 line-paper feeding)
Print head 150 km
Autocutter 1,500,000 cuts
(At room temperature and normal humidity with specified original paper type no. being TF50KS-EY,
PD160R, KT55FA)
Note: End of life is defined as the point at which the component reaches the beginning of the wearout period.
(2) MTBF
360,000 hours
Note: Failure is defined as a random failure occurring at the time of the random failure period.
(3) MCBF
65,000,000 lines printed
Note: This is an average failure interval based on failures relating to wear-out and random failures
up to the service life.
