4 Remove the tape seal.
Hold the cartridge in place with one hand and, using your other
hand, grasp the orange tab on the right side of the tape seal.
Keeping the toner cartridge parallel to the flat surface, pull the
orange tab straight out (26.4"/67 cm). Discard the orange tab and
tape seal.
▲ Caution: Once the toner cartridge is installed, each time the front
cover of the printer is opened, the drum protective shutters open and
the drum surface is exposed to light. This may deteriorate the drum
and reduce print quality.
