The 44XL is a high yield, black inkjet cartridge manufactured by Lexmark for use in its line of home printers. While you can purchase an entirely new replacement cartridge if you like, it is also easy and possible to refill this cartridge at home. Properly refill new black printer ink into the high yield cartridge and you can quickly return to your printing duties.
Take the Lexmark 44XL cartridge out of your Lexmark printer and position it onto a flat surface protected by a few layers of newspaper or paper towel.
Pull off the label on the top surface of the Lexmark 44XL cartridge.
Slowly fill your plastic refilling syringe with up to 15ml of black replacement inkjet ink.
Position the tip of the syringe into any of the refill holes on the top surface of the Lexmark 44XL cartridge.
Push the syringe's plunger slowly to begin releasing the black replacement ink into the cartridge.
Finish releasing all of the ink, then carefully remove the syringe from the refill hole and allow the cartridge to sit upright inside the printer for eight hours before continuing printing.
