How do I replace the toner cartridge?

First, ensure the printer is powered on and open the print cartridge access door. Grasp the handle of the old toner cartridge and pull it straight out, then unpack the new HP 88A Black Original LaserJet Toner Cartridge and shake it 6 to 8 times to distribute toner evenly. Remove the orange sealing tape completely, insert the new cartridge into the printer until it clicks into place, and close the access door.
