Caren 18:40 07 Dec 2015 Locked My printer has been behaving beautifully for months, but the ink was low so I have today replaced both cartridges with genuine Canon cartridges. The printer displays E 5 and I can't remember how to get it to work from this point. Help please! Bris 18:54 07 Dec 2015 This may help This thread is now locked and can not be replied to.
