Cannon cartridge
The order came quickly and at a reasonable price. The color one kept blinking so I did what they recommended I do but nothing worked. House of toner's was nice enough to replace the color cartridge which did stop blinking but the black cartridge then started blinking. I went through all of the cleaning process again but finally just gave up. I'm beginning to think it's as much an issue with my printer more than it is the cartridges.
