HP 31 70-ml Cyan Original Ink Bottle, ~8,000 pages, 1VU26AN

This product is exactly what I needed! It was received intact and unopened, it was simple to open, and even more simple to install into my printer. All of what I've printed has been flawless with this ink. I intend to invest again.

One bottle of black ink will last our family about a year. Does not smear. It's the only way to go and save a lot of money.

The refill was easy enough to use but the printer wasn't quite ready for the whole 135 ml. I added it and when it was full it just stopped. Now I have about a half inch of ink left in the bottle. Hope it keeps.

I not only love my HP printer, but the ink bottles are so easy to use with no mess. The initial install of the inks was very easy, and the Black replacement bottle of ink was just as easy.

good quality

‏i love the service

Easy to Install, and reorder.. love how long it lasts!

The problems I'm complaing about is actually with the single black in bottoles. My black in on my tank printer was empty. After installing a new bottle following instructions we notced the black in under the printer. I assume the amount in the bottle was too much for the ink resivoir and overflowed. It did clean up a lot easier than we expected. In other words it did not stain the area underneath the printer at all. It is possible it was operator error. Maybe the printer in fact was not all the way empty. I do not know that answer. I am 80 so maybe it was just me that messed up?

Even with high quality print paper and applying the noted settings, the color contrast does not appear in print as it does on screen. Notably "blue" is a more muted blue in appearance and "purple" is much more subtle, "red" less rich, even with bold, that appears on screen. Disappointing contrast on new printer so the print heads are new and tanks are full.

Kind of difficult to install. Have to turn them upside down.
