Why? I dont want to put another new cartridge in for the same thing to happen again. Is there a reason why the new cartridge just filled up like that? please help</P> Tue, 28 Mar 2023 13:43:47 GMT https://community.usa.canon.com/t5/Production-Printing/imagePROGRAF-iPF8400S-New-Maintenance-Cartridge-Immediately-Full/m-p/411794#M782 spec1 2023-03-28T13:43:47Z https://community.usa.canon.com/t5/Production-Printing/imagePROGRAF-iPF8400S-New-Maintenance-Cartridge-Immediately-Full/m-p/414510#M809 <P>Hey, exact same thing just happened to me!
