Precautions
The following precautions will help to ensure that this machine will continue to function correctly.
•Try to avoid locations that have the following adverse conditions:
* Temperatures out of the specification * Direct sunlight * High humidity
* Shared power source * Excessive vibration * Dust/Gas
•The cover should be cleaned by wiping with a dry cloth or a cloth slightly dampened with a mild detergent solution. NEVER
USE THINNER OR ANY OTHER VOLATILE SOLVENT on the plastic covers.
•USE ONLY Oki Data SPECIFIED paper and ribbons.
•DO NOT STORE the paper or ribbons where they might be exposed to direct sunlight, high temperatures, high humidity, dust,
or gas.
•Ensure the printer is operated on a level surface.
•Any data stored in the memory of the printer could be lost during a printer fault.
•Try to avoid using this equipment on the same power supply as high voltage equipment or equipment likely to cause mains
interference.
•Unplug the machine whenever you are working inside it or cleaning it.
•Keep your work environment static free.
•Do not place heavy objects on top of the machine, as these items may become unbalanced and fall causing injury.
•Do not block the ventilation slits of the machine, as this will cause heat to build up inside the machine and may cause fire.
•Do not lean against the machine. It may fall on you and could cause injury.
•Unplug the machine when it is not used for a long period of time.
•Place the machine on a stable and level surface.
• Do not turn on the printer power while the ON LINE and ERROR lamp are blinking as this may cause damage to the printer.
•RISK OF EXPLOSION IF BATTERY IS REPLACED BY AN INCORRECT TYPE.
DISPOSE OF USED BATTERIES ACCORDING TO THE INSTRUCTIONS.
Request Regarding Maintenance
•Utilise our maintenance services.
After purchasing the machine, contact your authorised Oki Data representative for assistance once a year to have the inside of

2.1 Installation
To insure the best operating environment and to assure the safety of the
operator and equipment, please observe the following precautions.
•Operate the printer on a stable, level surface in a location free from
excessive humidity, high temperature, dust, vibration and direct
sunlight.
•Keep your work environment static free. Static discharge can cause
damage to delicate internal components.
•Make sure the printer is connected to a clean source of AC power and
no other high-voltage devices, that may cause line noise interference,
are connected to the same mains.
•Assure that the printer is connected to the AC mains with a three-
prong power cable that has the proper ground (earth) connection.
•Do not operate the printer with the cover open. Be careful not to
allow fingers or articles of clothing to get caught in any of the
moving parts, especially the optional cutter mechanism.
•For best results, and longer printer life, use only Oki Data
recommended media and ribbons.
•Store the media and ribbons in accordance with their specifications.
•This printer mechanism contains high-voltage components; therefore
you should never remove any of the covers of the machine as you
may receive an electrical shock. Additionally, the printer contains
many delicate components that may be damaged if accessed by
unauthorised personnel.
•Clean the outside of the printer with a clean, dry cloth or a clean cloth
slightly dampened with a mild detergent solution.
•Use caution when cleaning the thermal print head as it will become
very hot while printing. Wait until it has had time to cool before
cleaning. Use only the Oki Data recommended print head cleaner to
clean the print head.
•Do not turn off the printer power or remove the power plug while the
printer is printing or while the ON LINE lamp is flashing.

2.3 Loading Supplies
1. Do not touch any moving parts, projection and the edge of sheet metal. To reduce the risk of
fingers, jewellery, clothing, etc., being drawn into the moving parts, be sure to load the supplies
once the printer has stopped moving completely.
2. The Print Head becomes hot immediately after printing, allow it to cool before loading the media.
3. To avoid injury, be careful not to trap your fingers while opening or closing the cover.
WARNING!
CAUTION!
1. Be careful not to touch the Print Head Elements when lifting the Print Head Block. This may
cause missing dots due to static electricity or other print quality problems.
2. When loading or replacing the media or ribbon, be careful not to damage the print head with hard
objects like watches or rings.
Since the print head element can be easily damaged by shock, please treat it carefully and do not
hit it with hard objects.
Care must be taken not to allow
the metal or glass part of a watch
to touch the print head edge.
Care must be taken not to allow a
metal object like a ring to touch
