Comments about HP 507X High Yield Black Original LaserJet Toner Cartridge:
My IT Department purchased non-HP toner for our LaserJet 500 Color MFP M575 and these "universal" toner cartridges were horrible. One day two following installation the Black toner cartridge started having "drop out" throughout every document that was printed it didn't matter if it was text or images. I order a new Black Toner Cartridge through Staples received it the next day and installed in the printer. I also told IT not to order "faux" toner cartridge any more only HP for my department.
Bottom Line Yes, I would recommend this to a friend
