These cartridges are simply a plastic tank that holds the ink. They have no affect with regards to the printing quality which is determined by the print heads situated inside your printer.
Some cartridges are fitted with removable seals to prevent toner leaking from the product. Simply pull the detachable plastic seal from the side of the cartridge fully to release the toner
If the print quality is poor or no ink is appearing on the paper then try doing 2-3 head cleans/nozzle cleans through your printer software to help the flow of ink leaving around 20 minutes between each clean. During this rest period, ink from the cartridge will migrate through the cartridge and absorb / push any trapped air from the print head.
