You'd have to look up your printer model to be sure. Mine is the ET 2550. You can recap the unused portion of the bottle and I don't think it ever dries up. I don't know how many pages, I just know that when I got my printer it came with one set of bottles and I didn't have to buy ink for 2 years at least. At that point, I only needed to buy a bottle of the black ink. I do quite of bit of printing. I have no idea how many pages.
Sorry, there was a problem. Please try again later.The ink hasn't dried up in my bottles after being opened. You can close them very securely. I've used ink from already opened/sealed bottles to top off my printer's tanks and it seems to work fine.
