2. Remove the old toner cartridge by holding it across the center,
squeezing the sides to loosen the pins on the back side from
the developer cartridge notches. Then, lift the toner cartridge
straight up and out of the printer (fig. 6.1), and dispose of it
following safety laws and regulations.
3. Remove the new toner cartridge from its protective bag.
(Toner cartridges are color-coded on the top. Be sure you have
the correct color cartridge.)
4. Hold the cartridge by the ends, and shake it horizontally (fig.
2.10). This distributes toner evenly inside the cartridge and
helps assure quality printing.
5. Hold and squeeze the toner cartridge across the center, and
align it with the developer cartridge of the corresponding color
(fig. 2.11). Make sure the toner cartridge’s color-coded pins
line up with the notches on the developer cartridge.
