– The printer driver may not be installed correctly. Uninstall and re-install the printer driver. Make sure that there is a direct connection between the printer and USB port of the computer. Reboot the computer with the printer`s USB cable unattached and reconnect the cable once the computer has restarted.
It`s usually because the printhead inside your printer is clogged or dried out. Like with most printers, Canon printheads can clog due to ink or dust drying up and collecting in the nozzle.
If there is plenty of ink and the printer does not print, clean the Print Head then print the nozzle check pattern to ensure ink is ejected properly. If the problem is not resolved after performing Print Head Cleaning twice, carry out the Print Head Deep Cleaning.
Check Cables and Printer USB Ports

Check all cable connections (including the power cord) on the printer side. If the printer does have power and you`ve properly connected the communication cable, but the printer is still not recognized, try switching to a different USB port on the PC.

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.
Sometimes power cycling your printer can resolve the issue. Turn off your printer and unplug it, wait 30 seconds, plug your printer back in, and then turn the printer back on.
Restart your computer – this often will recover any lost connections with wireless devices. Power off and on the printer, and even the access point or wireless router your printer connects to. Check your printer configuration – you may not be assigned to the correct port for the printer.
Restart the printer and try again. Unplug the printer from an outlet. You can plug it back in again to see if it works this time. Check if the printer is properly set up or connected to your computer`s system.
Check6 Make sure wireless signal is strong. Monitor signal strength and move printer and wireless router as necessary. Place the printer and wireless router where there are no obstacles between them. Wireless communication between different rooms or floors is generally poor.
The easiest way to connect the Canon printer to the computer is via a USB cable. It`s the traditional method of connecting devices. One end of the USB remains connected to the printer, and the other must be connected to the computer`s USB port.
If you connect the printer to your computer via a USB cable, check whether the cable is properly connected. If it isn`t, re-plug it and make sure they are properly seated into the ports on both your printer and your computer. Try another USB port on your computer in case the one you previously used is broken.
Connect your printer via a USB cable

Simply plug one end of the cable into the USB port on the Canon printer and the other into the USB port on your computer. Then, plug in the power cable and turn on the printer.
