Cannot Print/Scan from Smartphone/Tablet

Check1 Check the power status of printer, network devices (e.g. wireless router), and smartphone/tablet.

Turn on the printer or devices.

If the power is already turned on, turn it off and on again.

It may be necessary to resolve wireless router problems (e.g. update interval of a key, problems of DHCP update interval, energy saving mode, etc.) or to update the wireless router firmware.

For details, contact the manufacturer of your wireless router.

Check2 Check the settings of your device (smartphone/tablet).

Make sure wireless LAN is enabled on your device.

For details, refer to your device's instruction manual.

Check3 Is the printer connected to the wireless router?

Print out the network settings information to check the connection status between the printer and wireless router.

• Printing Network Settings

Make sure "Active" is printed on "Connection" under "Infrastructure".

If "Inactive" is printed, connect the printer to the wireless router.

Check4 Are network settings of printer identical with those of wireless router?

Make sure the network settings of the printer (e.g. wireless router name, SSID, network key, etc.) are identical with those of the wireless router.

To check the settings of the wireless router, refer to the instruction manual provided with it or contact its manufacturer.

To check the current network settings of the printer, print out the network setting information.

• Printing Network Settings

If the network settings of the printer are not identical with those of the wireless router, match the network settings of the printer to those of the wireless router.

Check5 Are network settings of your smartphone/tablet identical with those of wireless router?

Make sure the network settings of your smartphone/tablet (e.g. wireless router name, SSID, network key, etc.) are identical with those of the wireless router.

To check the settings of your smartphone/tablet, refer to the instruction manual provided with it.

If the network settings of your smartphone/tablet are not identical with those of the wireless router, change the network settings of it to match with those of the wireless router.

Check6 Make sure the printer is not placed too far away from the wireless router.

Place the wireless router 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.

Note

• Though an antenna is attached to most wireless routers, note that some of them have it inside.

Check7 Make sure wireless signal is strong. Monitor signal status and move printer and wireless router as necessary. (Windows)
