Status
The printer has detected
the external modem that
was once connected to
the serial port is no longer
responding. If the printer
has been configured to
receive faxes from a serial
port and the Fax Port
setting is not set to
disabled, it polls the
modem. If it detects the
modem connection is
missing, it displays the
attendance message. If
the modem connection is
re-established, the printer
removes the message
from the display.
An External Network
Adapter (ENA) that was
once connected to the
standard parallel port is no
longer responding. The
printer only recognizes the
missing connection when
the printer power is first
turned on.
The printer software has
detected that a network
port is installed and
cannot establish
communications with it.
Action
If the modem has been
intentionally disconnected,
you can press
Go
the message and continue
printing.
• Be sure the cable
connecting the ENA and
the printer is securely
attached.
• Turn the printer off and
then on again to see if the
printer recognizes the
connection.
• Press to clear the
Go
message. The printer
erases any reference to
the ENA and then resets.
Press Go to clear the
message. The printer
disables all communications
to the associated network
interface. No data can be
transmitted through this
interface. You can program
new firmware in the network
interface through the
parallel port after this
message clears.
