Cautions Regarding Paper
• Use roll paper having a φ15 inner diameter or greater (with no core)
and a φ83 outer diameter or smaller.
• Depending on the usage environment or paper conditions, even
when using recommended paper, sticking (a phenomenon where
paper sticks to the thermal printhead during printing) may occur. It
may make some text unreadable or missing in print out, or result in
a paper feed error.
Sticking is likely to occur when coverage is high (horizontal lines,
logo marks, etc.), in a low temperature environment, when printing
at low speed, etc.
Before printing, check the operation by using the paper that you use
for actual printing, at the actual temperature and humidity levels,
under the actual operating conditions.
• Thermal paper does not like an environment where temperature or
humidity is high. Especially when temperature reaches 60°C
(140°F) or higher, discoloring begins. Take extra care when storing
paper.
If the temperature becomes high while paper is caught in the paper
output section, the paper components may begin to melt and cause
the paper to stick to the thermal printhead.
• When using perforated paper, perforate it from the heat-sensitive
side. Note, however, that the burr height or paper chips generated
during perforating may lower the print quality or cause the printer to
malfunction. Take extra care.
• Do not pull paper or cover the paper output section during
operation.
• Use the type of roll paper whose heat-sensitive side is on the
outside of the roll.
• Use paper that is not deformed or loosened, as shown below.
