benzene or paint thinners, otherwise the printer may become
discolored or deformed. (→ Refer to page 14.)
" When using optional accessories, use them as described in
their instruction manuals.
" Use thermal paper with this printer. If printed text is written
over or stamped, the text may disappear or become discolored. In addition, it may take some time for the ink to dry.
" Do not touch the printer with wet hands.
" Do not leave paper cassette cover open when storing as this
may cause paper misfeeding or a paper sensor error.
xi
" Concerning the paper cassette and the handling of the paper
! Store the paper cassette away from extremely hot,
extremely humid or extremely dusty locations and out of
direct sunlight, otherwise the paper may become discolored or a malfunction may result.
! Be sure to close the lid of the paper cassette before storing
it, otherwise the paper may become discolored.

sun, otherwise they may become discolored.
! After opening the package of paper cassettes, close it
again as soon as possible, otherwise the paper may
become discolored.
! Do not use paper that has been exposed to condensation.
! Do not try to use paper transferred from one paper cassette to another, otherwise a malfunction may result.
! Do not try to reuse paper that has already passed through
the printer, otherwise a malfunction may result.
! Do not open the paper cassette cover or pull out or push in
the paper while the printer is printing, otherwise a malfunction may result.
! Do not use folded, curled, cut, wet or damp paper, otherwise a paper misfeed or a malfunction may result.
! Do not touch paper cassettes or paper with wet hands,
otherwise a malfunction may result.
! Do not prepare or replace the paper cassette in an
extremely humid location, otherwise a malfunction may
result.
xii
Precautions
! Depending on the environmental conditions of the location
and the quality of the material that the adhesive-backed
paper is attached to, the adhesive-backed paper may
become discolored, peel off, be difficult to remove, leave
adhesive behind or damage the surface that it was affixed
to. Before using the adhesive-backed paper, test it by affixing a small piece to an inconspicuous area of the intended
surface.
