Part 16
•
Do not set any liquid or drinks such as coffee on the printer case.
•
Do not touch any metal part to avoid possible electrostatic damage.
•
Do not touch the areas around the print head and motor during or right after
printing. It can be very hot.
•
Do not allow the cut receipt to slide back into the cutter during the
operation. As this would lead to multiple cutting at the lower edge of a
receipt and the multiple cut thin slips tend to cause mechanical malfunction.
•
Use a grounded AC power outlet with only the power cord and power
adaptor furnished with the printer.
•
Do not use a power outlet of a circuit shared with any equipment that uses
a lot of power or causes great electrical noises, such as a copier, electric
motors or a coffee maker.
•
Do not use thermal paper containing Sodium (Na+), Potassium (K+) and
Chlorine (Cl-) ions that can harm the print head thermal elements.
•
If the surface of thermal paper is scratched with a hard object such as a nail,
the paper may become discolored.
•
If thermal paper touches diazzo copy paper immediately after copying, the
printed surface may be discolored.
•
Use only water paste, starch paste, polyvinyl paste or CMC paste when
gluing thermal paper.
•
If thermal paper touches anything containing phthalic acid ester plasticizer
for a long time, the image formation ability may be reduced or the printed
image may fade.
•
Use of volatile organic solvents such as alcohol, ester and ketone or some
adhesive tapes on thermal paper can cause discoloration.
•
Thermal paper must not be stored with the printed surfaces against each
other as the printing may be transferred between the surfaces.
•
Since the paper roll is highly thermal sensitive, please keep them in a dark
place that is 20º and 65% RH when not installed in the printer. Avoid
extended exposure to direct light. Use only products made from
polyethylene, polypropylene or polyester for storage of thermal paper.
