Canon Pixma G620 Streaky

Hey, so I bought a Canon Pixma G620 for my cricut to make stickers. It keeps printing streaky and certain colours look faded. I’ve tried going through the cleaning setting in it several times and it’s not helping. Does anyone else have this printer or a similar problem that has resolved it? It’s very frustrating. It’s an eco tank so everything I’ve found online is pertaining to regular cartridge printers.
