To prevent possible malfunction or failure observe the following:
• Avoid operating the printer without roll paper properly loaded or
with paper not complying with specifications.
May damage thermal head or result in poor print quality.
• Avoid using torn pieces of paper or spliced with plastic adhesive
tapes.
• Avoid forcibly pulling already loaded paper by hand.
• Avoid wedging the paper in by the printer cover.
May jam paper. To release, refer to "Removing Jammed Paper"
in this manual.
• Avoid using a sharp pointed device to operate panel keys.
Neglecting these cautions may result in printer malfunction or
failure.
To prevent injury and printer failures from worsening, observe the
following:
• In case of trouble do not attempt to repair the printer.
Leave it to our service engineer.
• Do not touch the printing surface of the thermal head.
• Be careful that the printer cover does not entrap your hands or
fingers.
• Be careful with sharp edges on the printer. Don't allow them to injure
you or damage property.
• Do not touch any of the moving parts (e.g. paper cutter, gears, active
electrical parts) while the printer is working.
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 supply outlet.
DAILY MAINTENANCE
Observe the following precautions for daily maintenance:
• When cleaning the printer, always turn it off and unplug it from the
supply 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, or
benzen.
• Never use a chemically processed cleaning cloth.
• To remove paper chips, use a soft brush.
• When transporting the printer, remove the roll paper from its paper
holder.
• When cleaning the thermal head surface, use a cotton gauze slightly dampened
with alcohol.
CAUTION
• Do not touch the thermal head's printing surface with bare hand or a metallic
implement.
• The thermal head is at a dangerously high temperature immediately after printing.
Allow it to cool off before launching maintenance work.
