Check 6
If problem occurs only when wireless router is in energy-saving
mode, turn off energy-saving mode of wireless router.
If the problem seems to occur suddenly, it may be resolved by updating the wireless router firmware (e.g.
update interval of a key, problems of DHCP update interval, etc.). For details, refer to the wireless router's
instruction manual.

If printer is connected to AirPort Base Station via LAN, make sure
you use alphanumeric characters for network name (SSID). (macOS)
If your network name (SSID) contains characters other than single-byte alphanumeric characters, the
connection is not established properly. Change the network (SSID) of the printer to use only single-byte
alphanumeric characters.
C-4
No default gateway is set.
When you set the IP address of the printer manually, enter a valid default gateway IP address. If you don't
know the default gateway, set the IP address to automatic.
C-7
There may be a problem with the signal.
Check the following items.
Check
Monitor signal status and move printer and wireless router as
necessary.
• Place the printer and wireless router where there are no obstacles between them. Wireless communication
between different rooms or floors is generally poor.
• Wireless communication can be impeded by building materials containing metal or concrete. If the printer
cannot communicate with the computer over a Wi-Fi due to a wall, place the printer and the computer in
the same room.
• After changing the installation location, print out the network settings information again and check the
status of the signal. Compare with the value in section "3-2-1" in the printed network settings information
and place the printer in the location with a higher value.
Note
• In some cases, "C-7" and "C-9" are displayed at the same time. In that case, refer to both items.
C-8
Too many clients are connected.
Wireless Direct does not allow more than 5 devices to be connected.
If you want to connect additional devices to the printer, unplug any devices that are not in use before
adding them.
