PRECAUTIONS ON PRINTER INSTALLATION
WARNING
Do not use or store this product in a place where it will be exposed to:
* Flames or moist air.
* Direct sunlight.
* Hot airow or radiation from a heating device.
* Salty air or corrosive gases.
* Ill-ventilated atmosphere.
* Chemical reactions in a laboratory.
* Airborne oil, steel particles, or dust.
* Static electricity or strong magnetic elds.
These locations create the risk of printer damage, as well as product fail-
ure, overheating, emission of smoke, re, or electric shock.
They can also result in re or electric shocks and so should always be
avoided.
Do not drop any foreign object nor spill liquid into the printer. Do not place
any object on the printer either.
Do not drop any metallic object such as paper clips, pins or screws into the
printer.
Do not place a ower vase, pot, or anything containing water on the print-
er.
Do not spill coffee, soft drinks, or any other liquid into the printer.
Do not spray insecticide or any other chemical liquid over the printer.
Dropping a metallic foreign object into the printer, may cause printer fail-
ure, re, or electric shock.
Should it occur, immediately turn the printer off, unplug it from the supply
outlet, and call your local Citizen Systems dealer.
Do not handle the printer in the following ways:
Do not subject the printer to strong impacts or hard jolts (e.g., being stepped on,
dropped or struck).
Never attempt to disassemble or modify the printer.
These actions create the risk of printer damage, as well as product failure,
overheating, emission of smoke, re, or electric shock.
They can also result in re or electric shocks and so should always be
avoided.
This device is not appropriate to be used where a child may be present.
Install, store, or use the device where it cannot be reached by a child.
Electric appliances could cause an unexpected injury or accident if they
are handled or used improperly.
Keep the power cord and signal cables out of the reach of children. Also
children should not be allowed to gain access to any internal part of the
printer.
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.

8——
CAUTION
Do not use the printer under the following conditions.
Avoid locations subject to vibration or instability.
Avoid locations where the printer is not level.
The printer may fall and cause an injury.
The quality of printing may deteriorate.
Do not obstruct the printer’s air vents.
Do not place anything on the printer.
Do not cover or wrap the printer in cloth or blankets.
Doing so could cause heat to build up and deform the case or start a re.
Avoid using the printer near a radio or TV set or from supplying it from the same
electric outlet as these appliances.
Avoid using the printer interconnected with a cable or cord that has no protection
against noise.
(For interconnections, use shielded or a twisted pair of cables and ferrite cores,
or other anti-noise devices.)
Avoid using the printer with a device that is a strong source of noise.
The printer may have an adverse effect on nearby radio or TV transmis-
sions. There may also be cases when nearby electrical appliances adverse-
ly inuence the printer, causing data errors or malfunction.
 Installed in any orientation other than those specied.
Malfunction, failure, or electric shock may result.
Connect the printer to a ground.
Electric leakage may cause an electric shock.
Do not connect the printer’s ground to any of the following:
A gas explosion could result.
* Gas piping
* Telephone line ground
* Lightning rod
 If lightning strikes a large surge of current may cause re or shock.
* Water pipes
Plastic water pipes should not be used for grounding. (Those approved by a
Waterworks Department may be used.)
Before connecting or disconnecting the grounding lead to or from the
printer, always unplug it from the electric outlet.

PRECAUTIONS IN HANDLING THE PRINTER
WARNING
Please observe the following precautions for power source and power cord:
Do not plug or unplug the power cord with a wet hand.
 Use the printer only at the specied supply voltage and frequency.
 Use only the specied AC adapter with the printer.
Use only the power cord that comes with the printer, and never use the supplied
power cord with another device.
Check to make sure that the supply outlet from which the printer is powered has
a sufcient capacity.
Do not supply the printer from a power strip or current tap shared with other ap-
pliances.
Do not plug the power cord into an electric outlet with dust or debris left on the
plug.
Do not use a deformed or damaged power cord.
Do not move the printer while its power is on.
Neglecting to handle it properly may result in printer failure, emission of
smoke, re, or electric shock.
An overload may cause the power cord to overheat, catch re, or the circuit
breaker to trip.
Do not allow anything to rest on the power cord. Do not place the printer where
the power cord may be stepped on.
Do not subject the power cord to severe bending, twisting, or pulling. Do not
carry the product while it is in this state either.
Do not attempt to modify the power cord unnecessarily.
Do not place the power cord near any heating device.
Neglecting these cautions may cause wires or insulation to break, which
could result in electric leakage, electric shock, or printer failure.
If the power cord sustains damage, contact your Citizen Systems dealer.
Do not leave things around the electric outlet.
Supply power to the printer from a convenient electric outlet, readily accessible in
an emergency.
Pull the plug to immediately shut it down in an emergency.
Insert the power plug fully into the outlet.
If the printer will not be used for a long time, disconnect it from its electric outlet.
Hold the plug and connector when plugging or unplugging the power cord or
signal cable after turning off the printer and the appliance connected to it.

10 ——
CAUTION
Caution label is attached in the position shown in the following gure. Carefully read the
handling precautions before using the printer.
These labels indicate that the head
becomes hot, so touching it may
cause burns, and touching the auto
cutter when opening the paper cover
may cause cuts on hands.
Do not transport this printer with the paper roll inside.
Printer failure or damage may occur.
To prevent possible malfunction or failure observe the following.
Do not open the paper cover during printing.
Avoid operating the printer without paper properly loaded.
 Avoid the use of paper not complying with specications.
May result in poor print quality.
Avoid using torn pieces of paper or paper spliced with plastic adhesive tape.
Avoid forcibly pulling already loaded paper by hand.
Avoid using a sharp pointed device to operate panel buttons.
Be sure to rmly insert the cable plugs into their mating sockets.
A cross connection may damage the printer’s internal electronics or the
host system’s hardware.
Only use the printer with devices that have designated solenoid specications for
the cash drawer interface connector.
Neglecting this caution may result in malfunction or failure.

11 ——
To prevent injury and printer failures from worsening, observe the following:
Do not touch the printing surface of the thermal head.
Do not touch any of the moving parts (e.g., paper cutter, gears, active electric
parts) while the printer is working.
In case of trouble do not attempt to repair the printer. Ask Citizen Systems ser-
vice for repair.
 Be careful that the covers do not pinch your hands or ngers.
Be careful of the sharp edges on the printer. Do not allow them to injure you or
damage property.
May result in electric shock, burn, or injury.
If the printer emits smoke, an odd smell, or unusual noise while
printing, immediately abort the current print session and
unplug the printer from the electric outlet.
DAILY MAINTENANCE
Observe the following precautions for daily maintenance.
When cleaning the printer, always turn it off and unplug it from the electric outlet.
Use a soft, dry cloth for cleaning the surface of the printer case.
For severe stains, use a soft cloth slightly dampened with water.
Never use organic cleaning solvent such as alcohol, paint thinner, trichloroethyl-
ene, benzene, or ketone. Never use a chemically processed cleaning cloth.
To remove paper dust, use a soft brush.
CAUTION
The thermal head is at a dangerously high temperature immediately after
printing.
Allow it to cool off before starting maintenance work.
