Refilling the coloured HP 951 cartridge:
Attention: Pictures 3 and 5 show how the cartridge looks inside. Do not disassemble the cartridge yourself! You would not be able to reassemble it tightly.
Draw as much ink as recommended into a syringe. Insert the needle into the cartridge carefully (picture 2). Make sure that the needle does not puncture the plastic bag inside the cartridge (see picture 3). This bag is not filled, it only compensates the pressure inside the cartridge while printing. Now carefully insert the ink. After refilling the cartridge, close the filler opening with one of our sealing plugs (pictures 4 and 5). Make sure that the sealing plug does not protrude from the guide rail. Otherwise you will not be able to reinsert the cartridge into the print head.

Refilling the black HP 950 cartridge:
Attention: Pictures 6 to 10 show an open cartridge in order to illustrate the inside. Do not disassemble the cartridge yourself!
To refill the black cartridge, proceed as with the coloured one. Drill a 3mm filler opening into the lower guide rail of the cartridge (picture 6). Carefully insert the filled syringe with needle into the cartridge (picture 7). Make sure that the needle does not puncture the plastic bag inside the cartridge. This bag is not filled, it only compensates the pressure inside the cartridge while printing. Then close the filler opening with a sealing plug. Make sure that the sealing plug does not protrude from the guide rail. Otherwise you will not be able to reinsert the cartridge into the print head.

Pictures 9 and 10 show the inside of the black HP 950 cartridge. Although the black cartridge has 2 ink chambers and 2 plastic bags, you can fill both chambers. The partition between the ink chambers is perforated in order to balance the filling level.
