Ah, one of life's great mysteries--what kind of toner is the right kind of toner? We have an unopened box of HP Laserjet 641A Cyan C9721A that is compatible with: HP Color LaserJet 4600, 4600dn, 4600dtn, 4600hdn, 4600n, 4610n, 4650, 4650dn, 4650dtn, 4650hdn, 4650n It is for a printer that has long since left us. Rather than keep this wonderful memento of technology gone by, we offer it to the greater good of libraries. Let me know if anyone wants it and we can send it your way via MelCat. Best Regards, Linden Godlove Administrative Assistant Bloomfield Township Public Library
