A:Answer To change the ink cartridges, you turn on the printer, open the front panel door. The cartridges move to the middle so you can remove them. Directions are on the door and in the manual that is on your computer when you install the printer. The printer comes with two cartridges 244 for color and 243 for black. The cartridges can be found where printer ink is sold. Don*t forget to align the print heads after installing the cartridges.
