If the printer is using wireless LAN, failure to print might result from a weak wireless signal.

Check the radio signal status of the wireless LAN in [System Settings]. If the signal quality is not satisfactory, move the printer to a location where radio waves can pass or remove objects that might cause interference.

You can check the signal status only when wireless LAN is used in infrastructure mode. For details about the radio signal status of the wireless LAN, see Checking the signal.
