How do I replace the toner cartridge on the HP LaserJet Pro MFP M226?

Lift the scanner assembly, open the top cover, and remove the old toner cartridge. Insert the new cartridge by aligning it with the tracks inside the product and pressing until firmly seated, then close the top cover and lower the scanner assembly. Before inserting, gently rock the new cartridge to distribute the toner and remove the pull tab and tape. Place the used cartridge in the bag from the new cartridge for recycling. (Page 25-27)
