Check3
Make sure printer is selected as connection for device (e.g. smartphone or
tablet).
Select the identifier for direct connection (SSID) specified for the printer as the connection destination for
devices.
Check4
Have you entered the proper password specified for the direct connection?
If the security setting of the direct connection is enabled, you need to enter the password to connect your
device to the printer.
To check the password specified for the printer, display it using the operation panel of the printer or print out
the network setting information of the printer.
• Display on the LCD.
• Print the network settings.
Check5
Make sure the printer is not placed too far away from the device.
Place the device and printer 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 wireless LAN due to
a wall, place the printer and the computer in the same room.
In addition, if a device like a microwave oven that emits radio waves of the same frequency bandwidth as a
wireless router is nearby, it may cause interference. Place the wireless router as far away from interference
sources as possible.
Place devices a suitable distance from the printer.
Check6
Make sure 5 devices are already connected.
Direct Connection does not allow more than 5 devices to be connected.
