Summary: HP LaserJet 64X Black Toner Cartridge, maximum capacity, as well as the printer are real work horses - performing very well. We print over 15K letters and envelopes per month and the cartridge actually prints about 20% to 25% over the stated throughput. It's also easy to install. Two issues that we have run into with our printer are with the fuser and ink smearing or build-up, and dust.
Excerpt: I've used HP for many, many years and in the past the"x" on the end meant that in was the high yield version of the same number cartridge with the "a" on the end. But the 64x does not fit the same printers as the 64a. Bought the 64x for the P4014n printer - wrong!! I guess there is no high yield cartridge for the P4014n.
Excerpt: This print cartridge is advertised as lasting for 25,000 pages. We have been using a new printer for the last 2 months which uses this cartridge. We have been averaging about 7,000 pages per 1 of these cartridges. VERY EXPENSIVE. I would NOT suggest purchasing this cartridge or any printer which takes it.
Cons: does not meet advertized yeild, very expensive
Excerpt: If you want this cartridge for HP 4014n Printer...STOP! DON'T BUY IT... IT DOES NOT FIT THIS PRINTER! We tried and it does not fit this printer, even though HP AND OFFICE DEPOT indicate it will work. IT WILL NOT FIT. Instead, use the #64A cartridge.... it will fit and works very well. Good Luck!
