We have both a high yield and low yield for this printer, these two are:


B4600C, Approx 7000 Pages. 


B4400C, Approx 3000 Pages. 

Although they are seemingly a bit different, both can be used for B4600. 

  1. When installing the new cartridge, as you remove it from it's protective bag, gently shake the cartridge as to free up all the toner and then peel/take of the protective sealing strip. Place the cartridge aside. 
  2. Open the printer door, turn the blue/colored lever towards you which unlocks the cartridge from the drum unit, and pull it out.
  3. Now place in the new cartridge where the previous one was and rotate the blue/colored lever to lock it in. You can now close the printer.
