large number of pages
has been printed.

The Wireless LAN
board can be accessed,
but an error has been
detected.
A destination is being
registered using Web
Image Monitor.
A network error
occurred.

firewall function is

Solution and reference
You may hear a rotating noise while the fan is
active, but you can continue using the machine
as usual.
Remove the paper from the output tray. When
the finisher tray is specified as the output
destination, press [Stop] to pause printing and
then remove the output paper to prevent paper
from falling off the tray.
Turn off the power of the machine, check that
the Wireless LAN board is correctly installed in
the machine, and then turn on the power.

If the message persists even after you have
turned the power off and then on, consider
repairing the machine.
Wait until the message disappears and do not
turn off the power of the machine. You may not
be able to perform operations for a while
depending on the number of destinations
being registered.
Check the connection between the machine
and the computer.
Add the destination list program to the
exception list in the anti-virus software on the
computer, or register the machine IP address to
the exception list in the firewall function. You
can check the IP address in [Check Status]
"Network".
