  3. This trick might work for a colored ink cartridge, but it's probably a better idea to use a black cartridge.
  4. Try to rest it sort of diagonally so that the part where the ink actually comes out isn't completely touching the paper towel or you could have a mess.
  5. No more than 3/4" from the very bottom.
  6. Make sure it gets past the surface of the water. Ink may (and probably will) come out, don't be alarmed!
  7. About 5 minutes in the sink should do the trick. Otherwise, you might have to wait up to 20 minutes.

The Last Resort Method

  1. This should be either electronic, sponge or open head. Electronic heads are normally covered with orange wire strips. Sponge heads are obviously sponge which can be touched. Open heads are a hole with nothing in them but ink.
    • For electronic heads, simply throw in trash. These heads are unreliable, especially if you don't print every day.
      1. Get rid of your printer. Give it away. Deliver it to your local thrift store.
      2. Buy a printer with sponge or open heads. These almost never dry out because the system keeps them sealed. Usually you will find these in printers with four or more cartridges; three separate colors and one black (aka CMYK).
    • If you have a sponge or open head cartridge, and you already did the other methods to no avail, your cartridge is dead. The ink has dried and hardened to a point it cannot be salvaged. Buy a new one. They can usually be found cheap on Ebay.

    Open the printer below the scan glass with the printer turned on and the cartridges will slide into view. Push them down to release them. Make sure when adding the replacement cartridge you remove any tape or other materials designed to protect the print heads.

      Tips

      • If you accidentally get some ink on a counter top or in the sink and can't get rid of it, use a bit of hydrogen peroxide and rub it off.
      • If you don't use your printer much (like most homeowners), cartridges drying out could be problem. You will want to get sponge head cartridges. These don't dry out as quickly.
      • Consider searching Ebay or similar site for specialty refillable or Continuous Ink Systems for your printer model. These are designed to be used a long time.
