Please check if your router is up to date by either unplugging it or restarting it.

Also, check the printer's firmware update, to do so go to Updating or Upgrading Printer Firmware.

Please restart the printer, computer, and router for solve this problem.
  1. Turn the printer off, and then wait 10 seconds.
  2. Disconnect the printer power cord from the printer.
