Note on installation
(1) The printer must be used indoors. If used outdoors, the printer may fail
because of dust.
Note on the modular connector
(1) This product uses a modular connector as a dedicated connector for the cash
drawer or customer display terminal. The connector must not be connected
with a connector that leads to a public switched line or other such destination.
Note on using the printer in special mode
(1) If a large diameter roll is used, paper may fold or unusual noises may be
heard. To prevent these problems, use a roll with a small diameter (φ50mm
or less). If a Windows PC is used as the host system, a utility program can be
used to make settings.
