Network Status

What to Do

Connected normally.

If you are unable to print, see 1 on What to Do.

  1. If you are unable to print, check the items below:

    • whether the computer is connected to wireless LAN
    • whether the firewall of your security software is enabled

    • whether a privacy separator, SSID separator, or Network separation function is enabled on your wireless router

      If one of the above is enabled, disable it before setup.

    • whether the SSID of the printer (see "3-2-6" of network setting information printout) matches that of the router to connect
  2. To change the network connection method (wired/wireless), change it on the printer's network setting screen.

Wireless LAN is disabled on the printer.

Perform printer setup following the instructions of the manual.

Wired LAN connection is disabled.

  • Make sure the printer is connected to the router with the LAN cable.

    If the LAN cable is loose, connect the cable properly.

    If the LAN cable is connected to the WAN side of the router, connect the cable to the LAN side of the router.

  • Make sure the network devices (e.g. hub or router) are turned on.

IP address is not assigned.

  • If you specify the printer's IP address automatically, enable DHCP on the router.

  • If you specify the printer's IP address manually, the address is disabled because it is out of the valid range. You specified (0.0.0.0) as the IP address, for example.

    Specify the valid IP address.

The default gateway is not specified.

Check the items below to communicate by hopping routers (e.g. using a cloud application).

  • If you specify the printer's IP address manually, make sure the correct default gateway address is specified for the printer manually.

  • Make sure the device specified as the default gateway is turned on.

  • Specify the default gateway address correctly.

    To check the default gateway, print out the network settings information.

    Note

    • For some printers, you can check the default gateway on the operation panel.

Cannot connect to the specified network.

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

  • If they are turned off, turn them on.

  • Make sure wireless signal is strong.

    Monitor signal status and move the printer and wireless router as necessary.

  • The security key specified for the wireless router may not match that you entered.

    The security key is case-sensitive.

    Enter the correct security key.

The number of connected clients reaches the upper limit.

Make sure wireless signal is strong.

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

  • Wireless Direct does not allow more than 5 devices to be connected.

    If you add a device to connect, disconnect a device you do not use before adding the device.

A link local address is assigned.
  • Perform printer setup again.

  • The security key specified for the wireless router may not match that you entered.

    The security key is case-sensitive.

    Enter the correct security key.

The specified SSID is left default value.

The SSID is not specified.

Enter the SSID specified for the destination.
