Whenusingtheprinter
Do not subject the printer to strong shocks by dropping or hitting it.
Avoid using the printer at the following location. It may cause failure.
◆Locations with much dust, particles, water or oil.
◆Locations with slanted surfaces or strong vibration.
◆Locations with direct sunlight. near heating/warming equipments, or temperature over
60℃.
◆Locations with temperatures of below -20℃, a relative humidity of 85％or more,
dew condensation caused by extreme temperature change.
◆Location with electromagnetic noise or corrosive gas.
Do not touch the dot line on the thermal head and driver IC with metal and sandpaper
etc. There is a possibility for damage of those parts.
Do not touch the dot line on the thermal head with your fingures. The contamination
may reduce the printing quality.
Do not use the printer if there is condensation occurs on the thermal head. If the
condensation occurs, keep the power off until condensation evaporates completely.
Do not block the paper exit of the printer.
Do not use a volatile chemical such as thinner or benzene.for maintenance work.
３
SK1-211/311
Do not pull the paper end from the exit forcedly when the printer cover is closed.
Turn off the printer power when trouble such as a paper jam occurs.
Do not use loose paper. It may cause paper jam.
Be careful of handling the thermal head to prevent heat elements and driver IC from
exposure to static electricity.
When setting the printer
The details such as the setting positions of the printer shall be reffered to “3-7．
Dimansions”
Set the printer horizontally to the level, and make sure so the level not to be slanted.
Handling printer unit
◆Never disassemble or repair the printer ,AC adapter or power cord by yourself.
◆Do not use any AC adapter and power cord other than those specified.
◆Do not bend the AC power cord or place heavy objects on it. Doing so may damage
the cord and cause fire or electric shock.
◆Never use a damaged AC power cord. It may cause fire or electric shock.
◆Do not drop any metalic objects nor spill coffee,water or any other liquid.
◆Do not use the printer in a places where it will be exposed to excess moisture
or water spray. It may result in electric shock, short circuit and failure.
◆Do not connect or disconnect the ACadapter with wet hands. It may result in
electric shock, short circuit and failure.
Warning
As the thermal head may be very hot immediately after printing, do not touch it to
avoid burning your fingers. Be sure that the thermal head is cool before replacing a
paper or cleaning the thermal head.
Do not open the paper cover while printing.
Do not pull the paper when the cover is closed.
◆In the following cases, turn the printer power OFF and unplug the AC power cord from
the outlet.
・Smoke, unusual noises or odd smells are emittied by the printer.
・When metallic objects is dropped or any liquid is spilled inside the printer.
◆Continueous use may lead to printer failure,fire and electric shock.
◆Make sure the fault does not continue and contact dealers for further assistance.
If the printer is not to be used, turn the printer power OFF and leave the AC adapter
disconnected from the outlet.
Caution
４
SK1-211/311
Remove the interface cable or AC adapter from the connector or the receptacle by
gripping the connector or the AC plug. Never pull the cable itself.
Doing so may damage the cable or adapter.
Handling Paper Roll
Use the specified paper or equivalent. Use of other paper may reduce life of the
thermal head and cause a decrease in printing quality
Especially sodium(Na+)、potassium(K+) and chlorine(Cl-) containing substances can
remarkably reduce the life of the thermal head.
Store the paper in a dry, cool and dark place.
When pasting printed pages, use water-bnased glue. (starch glue, synthetic glue, etc.)
The surface of thermal paper has been specially treated with a chemical agent to
produce coloring by thermal chemical reaction.
◆Do not expose the paper for a long time under bright light.
◆Avoid storing in high temperature, high humidity,damp area and
direct sunlight.
◆Do not rub the paper with hard objects.
◆Keep the paper away from organic solvents.
◆Do not let the paper touch vinyle chloride film, erasers or adhesive tapes for hours.
◆Do not place he paper on diazo print paper or wet, freshly made paper copies.
◆Do not touch the paper with wet hands. It may cause fingerprint to be marks on the
paper or smudges.

SK1-211/311
3- 2．Sensor
(1) Paper-end sensor
The paper-end sensor is installed into the paper path and the photo-interrupter detects the
existence of paper in the printer. When the paper runs out, the red LED lights and the printer
goes into error mode and stops in the printing process.
After the paper is replaced, the printer resumes printing.
・Once the paper end sensor sends the paper empty signal, the printer stops printing.
・As soon as the paper end strip appears, replace the paper roll.
(2) Head open sensor
The head open sensor detects whether the print head is open or closed. Once the sensor detects
the head open signal, the printer stops printing and goes OFF-Line, the Error LED lights Red. The
printer resumes printing after the head is closed.
(3) Thermistor
The thermistor built in the print head detects the temperature of the print head.
If printing at a high printing rate for a long time, the print head temperature rises and
the head may become overheated. To prevent overheating, the printer stops printing when the
temperature is beyond a certain level, and blinks the red Error LED.
