Check1 Make sure that the printer is turned on. Check2 Make sure that the Wi-Fi lamp is lit on the front side of the printer. If the Wi-Fi lamp is off, Wireless LAN is inactive. To activate Wireless LAN, press and hold the RESUME/CANCEL button, then release the button when the POWER lamp flashes white 10 times.
Canon printer not recognising a new ink cartridge

Hold down the stop / cancel button for 5 seconds to bypass the `ink has run out` message and your cartridge should work. The cancel button is a red button that normally looks like a triangle in a circle.

Ensure Proper Ink Cartridge Insertion

There is a possibility that it didn`t properly click into the designated slot. If this is the case, you should lift the cover and double-check in order to verify that the cartridge is clicked into place. Otherwise, it would not be possible for the printer to detect it.

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.
Just above the circuit board on most printer cartridges, you`ll find a small button. You`ve seen these tiny buttons before on cell phones, phone chargers, etc. This is your reset button, and the only way to get in there is either with a paper clip or the tip of a pen (which will leave a tiny ink smudge on the button).
The most common reason a refilled ink cartridge does not work is that you didn`t reinstall the cartridge properly. Check the cartridge and make sure it is not dislodged or misaligned. If there is no visible sign of misinstallation, remove the cartridge and reinstall it.
Verify the ink cartridge(s) is inserted properly. Some cartridges snap in place, and if they are not inserted fully, the printer won`t print anything. If a lever is moved from its original position to allow for installation of ink cartridges, ensure it is returned to its original position.
Press the button on the chip-reset tool for several seconds until the LED light on the device goes off. Then, unlock the reset tool from the cartridge. Use the resetter with other cartridges and install them back into the corresponding slots in your printer. Voila!
This error occurs due to the chip on your cartridge still reporting a low or empty ink level from its previous use. The chip itself cannot be reset, so when the cartridge is refilled and then installed into a new machine it will still register as empty.
Remove and Re-Add Your Printer in Windows

If this happens, go to Settings > Devices > Printers & Scanners, select your printer, and remove it. Then click Add a Printer or Scanner to re-add it to the device list.

Make sure printer is turned on. Press and hold Wi-Fi button and release it when POWER lamp flashes 3 times. Make sure POWER lamp changed from flashing to lit.
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.
