Hi everyone, I recently got the Canon Pixma G6020 and I'm using it to make stickers for my art and whenever I print, there is always some vertical blue streaks showing up and I don't have any clue on how to fix it? I am currently using sticker paper with the photo "best quality" media setting. I opened up the inside of the printer and it kind of looks like it's a little dirty inside too? But im not too sure if that's what is causing the streak?
