Extended I/O Interface
If you have installed a commercial modular input/output (MIO) card in
the printer, you can select the extended I/O interface in this mode. If the
installed MIO card requires any optional interface settings, they appear
under this menu. To set them up, referring to the manual for the MIO
card.
Note
This setting appears only when an MIO card has been installed. For
installation of the MIO card, see the Network manual.
The network card may be pre-installed on some HL-3400CN series
