A:Answer Hello, the ink is different, and more economical for the 7602.
Ink for 6000 are cartridges (very expensive)
Ink for 7602 are bottles that customers use to fill reservoirs located inside the printer (very affordable, User & Environmentally Friendly, and not messy) You also receive 2 years of FREE Ink when you purchase this model!!
Hope this information was helpful!! The HP 7602 is truly a “Best Buy”!!
