Restart the printer and the computer or mobile device to clear possible error conditions. Restore Wi-Fi setup mode. Most printers with a touchscreen display or menu: Open the Wireless or Setup menu, select Network setup or Settings, and then select Restore Network Settings.
The printer is either low in toner, the density is set too low, or the Economode may be turned on. Remove the toner cartridge and shake it. This will redistribute the toner and often will temporarily solve the problem. However, this usually indicates it is time to install a new cartridge.
Check cables or wireless connection

Make sure that the printer`s USB cable is properly connected from the printer to your PC. If your USB isn`t recognized, see Automatically diagnose and fix Windows USB problems. Check the wireless connection (for wireless printers).

Make sure your Wi-Fi network and printer setup meet connection requirements. Restart the printer and the computer or mobile device to clear possible error conditions. Make sure the printer is not connected to a computer with a USB cable.

In Windows, search for and open Add a printer or scanner . Click Add a printer or scanner, and then wait for Windows to locate available printers. If your printer is found, click it, and then click Add device to complete the driver installation.
Make sure that both ends of the USB cable are correctly inserted into the computer and the printer. Try disconnecting and reconnecting the USB cable at both ends. Disconnect the printer and the computer and reconnect them. Try another USB port if available.
