Working drum AND toner from an OKI C3200 color laserjet printer. I have included the "printer summary" sheet showing the remaining life of the toner and drum. It shows 36% for the toner and 56% for the drum. HOWEVER, if I am correct, the useful life is what YOUR printer shows. It only reverts back to 100% if you install a NEW drum (or toner). So, if your printer shows 80% useful life of your drum (or toner), that's what it will show when you install this one. If your printer shows 20%, that's what it will show when you install this one. I also have the black and yellow ones listed as well as the fuser and belt. If you need any OTHER parts for this printer, let me know.
