4x4oz Nano Refill Ink and 4 Refill Syringe for HP940 cartridge for HP Officejet Pro 8500 printer , HP Officejet Pro 8000 printer ...

The package includes 4oz black ink, 4oz cyan ink, 4oz magenta ink, 4oz yellow, and 4 syringes. This water-based photo dye ink or UV dye ink is specially designed desktops and wide-format inkjet printers for photo or indoor advertising printings with a vivid color. Note: If the cartridges need to change ink from dye ink to pigment ink, or from pigment ink to dye ink, it's better to do 3 print head cleanings at once after installing the new ink. That will prevent these two types of inks from bonding together and clogging the print heads. The ink is compatible with the HP printers: Officejet Pro 8500 All-in-One and HP Officejet Pro 8000 Printer series.
