How do I change the ink cartridge on my lexamark

Hi there.
You open the lid on the front/top of the printer.
Then the printer will set up the print head with the cartridges in the middle. There are white plastic clips on front of each cartridge, pull them gently towards you and the cartridge moves slightly up or you will have to pull it up. To put the new one is you must first take all the wrapping off the cartridge and twist the orange lid off the bottom of the cartridge. Make sure you put the right one in the right place. Push them gently down until you hear a "click" close the lid on the printer and carry on printing.
