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.
