You can do virtually nothing with your HP Photosmart 6512 E-All-in-One when it runs out of ink, so make sure you always have replacement HP ink cartridges on hand. But the cost of OEM cartridges can be very high, so this is probably why you can’t get a replacement easily. Our remanufactured HP 564XL ink cartridges are rebuilt to strict quality control standards to ensure they meet or exceed OEM specifications.
