Use thermal paper with this printer. If printed text is written
over or stamped, the text may disappear or become discol-
ored. 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.
