I put the new cartridge in our printer, and, it doesn't work. I note on my Google search that this is a common problem with the 564 printers. I continue to do the things the search tells me such as cleaning the printer heads, printing a test sheet...no black. Pretty frustrating.
The ink always runs out way before it should. I get nowhere near the yield that's advertised. I'm stuck until I get a new printer and it won't be an HP
