configure the Wi-Fi network settings.
• Move your printer to an obstruction-free area.

cordless phone, or other device is near your printer or the wireless access
point/router, move the device away from your printer or wireless access point/
router.
Move your printer to an obstruction-free area.
You can confirm the MAC address by printing the Printer Settings Report. For
more information, see Related Information.
• Make sure the printer is in the mode you want to connect to.
• If the printer is still not connected, do the following:

complete.

If the Wireless Direct icon is displayed on the LCD, search for the printer
from the device you want to connect.
- For Wired LAN
