Check your network settings.

"Network Problems (MF4890dw/MF4870dn/MF4780w Only)"

YES

Are you connected with the wireless LAN?

YES

Check the following

The distance between wireless LAN router/access points is within 50 m (may vary on the communication speed or environmental condition).

There are no obstacles between the wireless LAN router/access point and the machine.

There are no microwave ovens or digital cordless phones near the installation area.

When multiple networks are used, to avoid interference between the channels, each network will be set to a channel that is as far apart from other network channels as possible such as Ch.1, Ch.6, and Ch.11.

For information on checking and setting methods for channels, refer to the instruction manual of the wireless LAN router/access point, or contact the manufacturer.

If there is no improvement:

Turn OFF the machine and wait for at least 10 seconds before turning it back ON.
