I purchased all 3 color cartridges because my printer said they were low. I found the override setting on the printer and thought I would see how much ink is left. To date I have still not replaced the old ones and I have printed 1600 yes 1600 pages since the printer told me to replace. Now most of what I print is black and white with small color thumbnails on the page. I print about 25 pages a week that are full color. So I suggest using the override setting a few hundred at a time to see where your limit is. So far, mine is showing no signs of color drain.
Switched back to HP cartridges, we were trying to save money so we were using re-manufactured cartridges, but had problems with the remanufactured units,one made rubbing noise and was not working at all. We were told by copier service tech not to use remanufactured cartridges because of quality of units.
