I had to replace 3 packs of Original HP color cartridges (cyan, magenta and yellow) less than 9 months after replacing them last year. (September 2020) This seems a bit off advertising as I rarely print more than 10 black and white sheets and maybe 2 color sheets in a month. I adjusted the print size, color, and font, but that didn't seem to reduce the amount of ink needed. Purple ran first. Yellow and blue levels have been found to be low and will soon disappear as well. It's just that I have an HP Deskjet 6600 and I'm not printing volumes and the display says I can print volumes of paper with a full black cartridge.
