In order to prevent injury hazard to operators, third parties or damage to property, special warning
symbols are used in this user’s manual to indicate important items to be strictly observed.
Please be familiar with the following precautions before reading this manual.
●The following describes the degree of hazard and damage that could occur if the printer is
improperly operated by ignoring the instructions indicated by the warning symbols.
Warning Neglecting precautions indicated by this symbol may
result in fatal or serious injury.
Caution Neglecting precautions indicated by this symbol may
result in injury or damage to properties.
This symbol is used to alert your attention to important items.

—3 —
●Never handle the printer in the manners described below; otherwise, it may be
damaged, get out of order or overheated, possibly causing smoke, fire or electric
shock.
If the printer is damaged or breaks down, be sure to turn off the power, disconnect
the power plug from the wall outlet, and contact your CITIZEN SYSTEMS dealer.
•Do not allow the printer to be subjected to any strong impact or shock, such as
stamping, hitting, dropping, and the like.
•Install the printer in a well-ventilated place. Do not use the printer in such a manner
that its ventilation slots are blocked.
•Do not install the printer in a place like a laboratory where chemical reactions are
expected, or in a place where saltish gases are present in the atmosphere.
•Use the printer only on the specified voltage and frequency.
•Do not connect/disconnect the power cord or data cable by holding the cable. Do
not pull or carry the printer in such a manner that undesirable force is applied to
the cables.
•Do not drop or insert any foreign substances, such as paper clips or pins, into the
printer.
•Do not connect the printer to an electrical outlet shared by other devices.
•Do not spill any liquid on or spray any chemical-containing liquid over the printer.
If any liquid is spilled on the printer, turn it off, disconnect the power cord from the
wall outlet, and contact your CITIZEN SYSTEMS dealer.
•Do not disassemble or modify the printer in any manner; otherwise, a fire or electric
shock may result.
●The plastic bag the printer came in must be disposed of properly or kept away from
children. Wearing it over the head may lead to suffocation.
WARNING

—4 —
●Do not use or store the printer in a place exposed to heat of fire, moisture or direct
sunlight, or in a place where the prescribed operating temperature and humidity are
not met, or in a place exposed to oily mist, iron powder or dust; otherwise, the printer
may get out of order, emit smoke or catch fire.
●Do not install the printer in a place like a laboratory where chemical reactions are
expected, or in a place where saltish gases are present in the atmosphere; otherwise,
there may occur a danger of fire or electric shock.
●Install the printer on a sturdy and good ventilation place and free from any vibration.
(Be careful not to block the ventilation slots of the printer.)
●Do not put any object on the printer, or this may cause a trouble.
●Do not use the printer near a radio or television receiver. Avoid sharing an electrical
outlet with a radio or television receiver, or this may cause a reception problem.
●Use the printer only on the specified voltage and frequency; otherwise it may emit
smoke, catch fire or cause other problems.
●Confirm that the wall outlet used for printer connection has sufficient electrical
capacity.
●Avoid sharing a single electrical outlet with other devices; otherwise, the electrical
capacity may be exceeded, causing the outlet to overheat or the power supply to be
shut down. Also, do not stamp or put any object on the cables.
●Never connect the grounding cable to a gas pipe, or this may lead to a danger of
explosion. Before connecting or disconnecting the grounding cable, be sure to
disconnect the power plug from the wall outlet.
●Be sure to turn off the power of the printer and the host computer connected before
connecting or disconnecting the cables; always hold both plug and cable. Do not
pull or carry the printer in such a manner that an undesirable load is applied to the
cables.
●Connect the connector cables correctly and securely. Especially, if a connection is
made with the polarity reversed, internal elements inside the printer may be damaged
or the host computer connected may be adversely affected.
●Use shielding wires or twist paired wires for signal lines in order to minimize the
effects from noise. Avoid connecting to a device that is likely to generate much
noise.
●Install and use the printer in a place provided with a suitable wall outlet nearby so
that you can immediately disconnect the power plug to shut off the power to the
printer if an abnormal condition occurs.
●When transporting the equipment, remove the paper roll from it.
PRECAUTIONS FOR INSTALLATION

—5 —
Do not handle the equipment in the following manners, because problems may result.
●Do not print when there is no recording paper or ink ribbon set in the equipment.
●Be careful not to drop foreign substances, such as clips, pins, and screws, into the
equipment.
●Do not spill any liquid or spray any chemical-containing liquid over the equipment.
●Do not stamp on, drop, hit, or give a strong shock to the equipment.
●Never use a pointed object, such as a pen, to operate the operation panel.
●Do not use Scotch tape to fasten paper together for continuous use.
●Never pull the set paper forcibly.
●Replace the ink ribbon before it is broken by overuse. Do not refill the ink ribbon.
●Leaving the printer unused for a long time with a ribbon cassette loaded may cause
smudged printing. Continuous printing at low temperature may cause thin printing
due to the characteristic of ink.
●Do not deliver the equipment with a ribbon cassette loaded.
To Prevent Injury and Spreading of Damage
●Do not touch the printing part of the print head.
●While the equipment power is on, do not touch the moving parts, such as a cutter
and gear, or electric parts inside the equipment.
●Be careful to avoid bodily injure or damaging other objects with an edge of sheet
metal.
●Should any error occur while operating the equipment, stop using it immediately,
disconnect the power plug from the plug socket, and then contact your CITIZEN
SYSTEMS dealer.

3.2 Part Descriptions
(1) DC jack Insert the output plug of the AC adapter attached.
(2) Power switch When switched ON, power is supplied to the printer and
the Power lamp goes on.
(3) Power lamp Lighted when power is turned ON and goes out when turned
OFF.
Blinks during memory switch setting and at the occurrence
of memory error. While memory switch setting error is
present, the Power lamp blinks at 1/10-second intervals.
While memory error is present, the Power lamp and the
SEL lamp blink simultaneously at 1/10-second intervals. The
memory switch setting error can be recovered by resetting
but memory error is not recoverable.
(4) SEL lamp Printer lights up in Select (ON LINE) state, and is put off in
Deselect (OFF LINE) state. Printing operation is available
only while this lamp is lit.

Supply paper and press the SEL switch to turn off the
lamp.
2) On occurrence of any alarm state (blinking) due to any
reason other than paper-near-end, it starts blinking at
1/4-second intervals. Eliminate the cause and either
press SEL switch or turn the power off and on again to
stop blinking.
(5) LF switch Paper is fed when switch is pressed (deselect condition
only). Used to supply paper or to insert some space in the
output.
(6) SEL switch Printer is selected (ON LINE) by pressing this switch.
Printer is deselected (OFF LINE) by pressing the switch
again.
Also used to release alarm state. In Deselect state, if data
still remain in the input buffer, they are all printed out.
(7) Interface connector Printer is connected to various hosts via cables. Please
ensure that both the printer and the host are turned off
before connecting.
(8) Printer cover Opened to exchange ribbon cassette and paper roll.
