How to install HP 850 ink cartridges?

  1. Turn on your printer, then open the top lid.
  2. Lift the cradle latch to remove the used cartridge.
  3. Get your new CompAndSave HP 850 cartridge. Open it over a sink or garbage can to avoid any mess in case it leaks, as sometimes, factories tend to overfill the ink cartridges. Make sure to touch the black plastic part only, then remove the covering tape that is usually bright in color along with the plastic protective case, if there is, before installing it.
  4. Insert the new ink cartridge into its slot until it snaps into place.
  5. Hold the cartridge by its sides with the nozzles facing the printer.
  6. Close the latch until it locks out.
  7. Close the top cover.

    Was an unexpected treat being able to find cartridge no longer stocked at the big office supply stores (for a largely obsolete printer!). These remanufactured cartridges seem to work fine and pricing from CompandSave is VERY competitive! Questions were promptly answered by capable associates with product shipped promptly. No complaints!

    I have an old HP960 inkjet printer and the ink is the least expensive which allows me to keep using the printer.

    When I needed ink, Comp and Save was temporally out of this product so I ordered from another vendor. The cartridge I received from the other vendor did not work. I called and they sent me a second cartridge. That didn't work either. By this time, Comp and Save had this back in stock and as usual, it works in my old HP Desk Jet 932C. Thank You Comp and Save!

    Price is good; one cartridge did not work at all and the others did not last long. I will not reorder these cartridges.
