I don't understand "cleaned these nozzles". The cleaning function is described at https://support.usa.canon.com/kb/s/article/ART162916.
As cleaning consumes a fair amount of ink others here and I have found that weekly-ish test sheets are a good way to keep the nozzles from drying out and clogging.
If this doesn't work I recommend calling Canon support at 1-800-OK CANON is 1-800-652-2666.
If Cannon cannot resolve the issue I found a mention of soaking the print head in online searches. This guy is using third-party ink, which I cannot recommend, but if all else fails it might be worth a try - https://www.youtube.com/watch?v=KKdCDqpa3XI
