HP Black Cartridge Refill InstructionsInstructions1. Put the cartridge on some paper towels in an area where you can tolerate a spill. 2. Peel off the top label. 3. Fill the syringe with 15 ml. of black ink. 4. Very S-L-O-W-L-Y inject ink into any of the front three holes (they all go to the same sponge). The back two holes is just an empty space, don't use them. 5. When finished leave the top label off and the filling holes exposed (when printing it has to pull in air). 6. Replace the cartridge and run 1 - 3 cleaning cycles as per printer instructions. The cartridge will print just like a new one. Even though the cartridge prints good, the ink level gauge will not read full after a refill. |
