HP #74 Cartridge
1. Put the cartridge on some paper towels in an area where you can tolerate a spill.
2. Peal off the top label.
3. Fill the syringe with 20
ml. of black ink.
4. Very S-L-O-W-L-Y inject ink into any hole (they all go to the same sponge, HP just used the same color mold for the black ink cartridges).
5. When finished, replace the top label or leave it off (it will make no difference in the printing)
6. Replace the cartridge and run 1 - 3 cleaning cycles as per printer instructions.

For best results, leave cartridge in printer for 8 hours after refilling so the ink can saturate the entire sponge.
