KS55 SERIES OPERATION MANUAL
2 - IMPORTANT NOTES ON THERMAL PRINTER HANDLING
In order to preserve the life of the printer, it is necessary to keep in mind some precautions on the
handling of the KS55 printer. Please read carefully the following points in order to make a good use of
the printer.
2.1 - SAFETY PRECAUTIONS
•
Before using the printer, read carefully section
- INSTALLATION.
•
NEVER
connect the external power supply with the wrong polarity. This could permanently
damage the printer.
•
Turn off the printer immediately if it produces smoke, a strange smell or an unusual noise. Keeping
on using the printer could cause fire. Unplug the equipment immediately and contact your official
distributor.
•
NEVER
connect cables with different connectors from the ones mentioned in this manual. Failing
on doing so could permanently damage the printer.
•
Use a power supply whose output voltage is within the specification range stated in this manual.
Over voltage can permanently damage the printer. Under voltage can cause malfunctions.
•
NEVER
wet KS55 thermal printer with water or any other liquid. If any liquid is spilled inside the
equipment, unplug the power cable immediately and contact the technical service.
•
Make sure the printer is on a steady, securely fixed surface. If the printer falls down, it could break
or damage.
•
NEVER
use the printer in high humidity or in locations with high risk of fire.
•
NEVER
place heavy objects on top of the printer and never lean on it.
•
NEVER
put any object inside of the printer, as it could cause hardware damage on it, such as
short-circuit, print head breaking or general failure of the printer.
•
NEVER
shake the printer.
•
NEVER
disassemble or modify the hardware of the printer.
•
NEVER
try to repair the printer. Please contact your official distributor in case of failure.
•
As the printer contains electromagnets (inside of the motor), it should not be used in excessively
dirty environments or places with dust or metal particles.
•
NEVER
print without paper loaded or without the cover closed, as the thermal print head life can
be highly shortened.
•
NEVER
pull the paper out when the cover is closed. Use the paper advance button instead.
•
Avoid touching accessible parts with metallic objects, such as screwdrivers or tweezers, the print
head thermal elements as well as the electronic printed circuit. They are delicate parts.
•
NEVER
touch with bare hands the areas around the print head and the motor surface as they
become very hot during and just after printing; wait 15 seconds after printing to let them cool down.
•
NEVER
touch the surfaces of the print head thermal elements or the electronic printed circuit, as
dust and dirt can stick to their surface and cause damage by electrostatic discharge. Moreover,
some electronic components can get very hot during operation.
•
The thermal paper contains Na+, K+ and Cl- ions that can cause harm to the print head elements.
Therefore, use only the specified paper.
•
If the printer has not been used for long period of time and the paper was loaded, the paper could
become deformed by the drive roller pressure. It is recommended to make it advance at least 30
mm before printing again.
•
For safety reasons, unplug the printer if it is not going to be used over a long period of time.
•
Do not print continuously (without stopping) for more than 6 minutes.
