Model: Canon Pixma ts6350
Problem: PGBK (probably), the bigger the letters the more visible white stripes, sometimes there are gaps between regular size letters too. It all started about week after purchase, I set it up, printed some test documents and photographs and it was all good, then I left it without printing for a week and this started happening...
I did: cleaning, deep cleaning, cartridge replacement, print head alignment (manual)
From my observations it seems like the more problem appears as more ink is being used at once, that could explain why printing smaller text usually gets less visible white stripes, also thin diagonal lines looks good
Here it happend more at the bottom of a document, dunno why or it's a problem with the print head
Nozzle check was a "little" misleading in this case, here everything seems nominal
Also it's pretty much ok when printing in higher quality, when it thinks it's a photograph so it uses K instead of PGBK, but it's not a solution.
I've printed around 40-50 pages since it started happening and it gradually becomes a little bit more bearable, but still it's not really usable for printing regular documents at the moment, I have no idea if it will magically recover by just printing more and more pages, please help me find a solution
