Paper
Paper types: Paper roll:Plain paper or pressure-sensitive paper
Paper roll width: 76 ± 0.5 mm (2.99 ± .020")
Paper roll maximum
diameter: 83 mm (3.27")
Paper roll core: Because the standard version of this printer is not equipped with a
mechanism that detects the amount of roll paper remaining (near-
end detector), paper rolls in which the paper roll core and paper
are attached to each other by tape or glue may jam. Because the
core will jam the paper guide, preventing paper from feeding
through. Make sure to detect the amount of roll paper remaining
with the optional near-end detector, or confirm the end mark of
the paper and change the paper with a new one when the paper is
attached in the core by tape or glue is used.

Printer Installation Position
Install the printer horizontally. Make sure it does not tilt more than 15°. The printer must also be
installed so that it does not move or vibrate during paper cutting or the drawer kick-out
operation. Fastening tape is available as an option.
