You could try replacing the cartages even if they are full of ink. I found new cartages fixed my problem even though the existing cartages were less than 15% used. Of course it is a complete rip off but that how Canon have set up the devices to trigger such errors and make you buy new supplies. I had an expensive Canon iX680 A3 printer which was used probably less than 25 times in the 3 years before it without warning trew up an error B200 and there was nothing I could do except return to the service centre and pay for the replacement of the entire print head that would cost more than the printer was worth so I had to dispose of it in ewaste. I wasted a lot of time trying to fix it forst and I was ledt with replacement ink unused in the fridge.
I had a BJC 6000 15 years ago which was also an expensive supposedly high end ink jet and it too was a world of pain, in fact never worked properly from new.
Fool me to ever buy a Canon printer but will not be fooled again
Good luck with it.
