MG6320 , always used after market inks past 5 years. One I was getting doubled like 3d text. so many deep cleans, took it washed in hot water sprayed with canned air, put back in , same thing, so I then ordered a print head from good ole' Ebay for 33...
I read other posts that ppl have this issue, because if 1 ink or few more are low, Canon forces you to buy the ink to replace the low ones, then you can print in greyscale ???
