refill kit

After spending all day trying to clear a code 1410 (cartridge not recognized) on my Canon Pixma iX6820 to no avail, until I drove to my local Staples for $85 worth of OEM XL carts... I now suspect that my remaining stock of cheap 3rd party carts ("Paeolos" brand) won't work. I know OEM Canon...

With my refund deposited, I made the jump and bought myself a new Brother color laser printer. This will be replacing the two other printers that have given me no end in being able to rescue. (That's for another thread) But I have a question: 1) I want to get a refill kit asap, so I am prepared...
