Installing the toner cartridge
1. Pulling the cover release buttons found on both sides of the machine
toward you, open the cover.
2. Unpack the cartridge from its plastic bag, and then remove the paper
rolled around the cartridge. Holding on to each end of the paper,
pull it straight out, and then carefully remove it.
3. Shake the cartridge from side to side 5 or 6 times to redistribute the
toner evenly inside the cartridge.
