Review on Original HP 64 Black/Tri-color Ink Cartridges (2-pack) | Compatible with HP ENVY Photo 6200, 7100, 7800 Series | Eligible for Instant Ink | X4D92AN by James Hova

You estimate 200 pages from this cartridge. We only print a few pages per week, standard forms that require a signature, etc. So pages with a lot of free space. After we printed about 10 pages, we started getting low ink messages. After another 10 or so pages, there were blank pages. I took out the cartridge and shook it. The next page prints fine, but the cartridge is clearly empty, so I'm ordering another one. I am very annoyed - it turns out to be very expensive per side.
