Hello Teddy - thank you for your feedback. The patented HP® cartridge is designed to always have some ink remaining in the ink cartridge to ensure the nozzles are able to fire properly - this extra ink is accounted for when filling the cartridges and they are rated to deliver 42ml of ink for you. If you feel you have any cartridges that are not printing completely as they should, please feel free to contact our Technical Services team to assist with diagnosing the root cause and provide general cartridge maintenance and care tips: 833-926-3464 x2 or support@sneedcoding.com
