Cartridge is reporting that it's empty

The cartridge installed is producing an error message saying that the cartridge is empty and is preventing printing.
Send a document to print.
Once the error message appears, press continue to clear it.
If the printer is unresponsive, hold down the stop/cancel button on the printer for 3-5 seconds.
Resend the document to print.

Cartridge missing or damaged

Remove the faulty cartridge from the printer.
Make sure all the packaging clips and blue tape covering the copper part of the cartridge has been removed from the cartridge.
Clean the contacts with a dry cloth or tissue.
Pull the power cable out the back of the printer and leave the printer off for 15 minutes.

Cartridge doesn't "light up"

The lighting of the cartridge has been patented by Canon, to prevent compatible manufacturers being able to offer this feature to their customers.
This is normal and does not affect printing.

Not recognised

Make sure the cartridge is securely clipped in and the printers cover is closed.
Check the status monitor, either on the printers control panel, or on the computer.
Remember, the compatible cartridge does not light up to avoid patents.
If the fault persists, remove the cartridge carefully to check the chip has not been dislodged.
Reinstall the cartridge.
If the fault persists, replace the cartridge.

Leaking ink

If ink is dripping after removing the orange clip, the internal foam may be out of position.
Blot the exit hole gently with tissue paper to help stop the leak.

Printing blank pages / fading on print

If the print quality is poor or no ink is appearing on the paper, try performing 2–3 head cleans/nozzle cleans.
Leave 20 minutes between each cleaning cycle.
If the issue persists, switch off the printer and unplug it for 10 minutes.
Re-install the cartridge and try printing again.
