Comments about HP 20 (C6614DN) Black Inkjet Cartridge:
For some time now I have been unable to purchase the HP20 black cartridges for the office fax machine except in a remanufactured version. HP machines seem to be built with some sort of a sensor that detects that it is not a new HP cartridge and begins to behave goofy. I finally remembered that HP direct might still carry this cartridge, and they did which I was very thankful for, I only wish they didn't put such a premium price on it . . . 3 times the remanufactured ones that are available. Other than that, working with HP directly is GREAT !
Bottom Line Yes, I would recommend this to a friend
