HEWLETT-PACKARD 51625A, and 51649A Print Cartridges

  1. Protect your work surface with newspaper or paper towels.
  2. Remove ink cartridge from printer according to manufacturer instructions.
  3. The cover must be removed before refilling. Remove plastic cover by carefully prying it off (use short-bladed knife, box knife, Exacto-knife or small screwdriver).
  4. Determine which chamber (cyan, magenta, or yellow) requires refilling. Fill the syringe with the appropriate color of ink. Insert the syringe tip at a "downward" angle into the fill hole as far as it will go. (Apply enough force to penetrate sponge inside.) Then draw it back about 1/4"(6 mm) to leave a well for the ink as it is dispensed. The chamber should hold approximately 5 mls. of ink.

  5. IMPORTANT! Slowly eject the ink into the cartridge, filling the chamber by pushing the plunger gently but firmly. Allow the ink to absorb into the foam sponge. DO NOT OVER FILL!
  6. Replace cap and secure with tape.
  7. Replace cartridge into printer. Run self-test or print head cleaning program. If printing is too light, remove cartridge and stand it upright on a dry paper towel. Let cartridge rest on wet towel for 3 to 5 minutes. Three spots of ink (magenta, cyan and yellow) should appear. Wipe cartridge and repeat self-test or print head cleaning program. Clean any ink on hands or surface with water.

Note: It is highly recommended that you refill the color chamber before it runs completely out of ink. As soon as a color of ink starts to skip, refill that color. Do not "top off" the other two colors, but refill each one as soon as it shows signs of skipping.

  1. Protect work surface with a few layers of newspaper or paper towels.
  2. Using the point of a sharp knife, carefully remove round black patch to expose ball plug which seals fill hole. Push ball plug into cartridge with ball point pen.

  3. Fill cartridge with 40 ml (15ml for model 6615) of black ink. DO NOT INSERT NEEDLE MORE THAN 1/2 INTO CARTIRDGE. (Cartridge has liner that may be damaged if needle is inserted more than 1/2. Once syringe is inserted, tilt back to vertical position and gently push in plunger to fill cartridge.
  4. Place new sealing ball over fill hole and press into place.
  5. Wipe any ink drips from around fill hole and apply a new round plastic seal over fill hole. Turn it over so printhead faces down and squeeze sides of cartridge firmly until several drops of ink are expelled from the printhead.
  6. Gently wipe excess ink from printhead.
  7. Let cartridge stand, print head down, for 30 minutes or more to allow any air to rise to the top of the bladder.

Note: Green-Black ink level indicator may not completely reset but will turn completely black when cartridge is empty. If ink continues to seep from print head when inverted press printhead against absorbent pad until seeping stops.

Hewlett-Packard 51641A, C1823, 6578 Tri-Color Cartridge

  1. Protect your work surface with newspaper.
  2. Remove ink cartridge from printer according to manufacturer instructions.
  3. Holding the cartridge upright, use the tip of a ballpoint pen, or similar object, to push the three plugs that seal the ink fill holes into the cartridge.

  4. Determine which of the 3 ink chambers is empty. (Only fill empty chamber) Fill the injecting syringe proper ink color (cyan, magenta or yellow).

  5. Tilt the cartridge forward so that you can insert the syringe into the correct fill hole without dripping. Insert the syringe plunger into the cartridge as far as it will go.
  6. Bring the cartridge and syringe back to the vertical position. Carefully inject the ink into the hole moving the tip so that the ink saturates all areas of the sponge inside the ink chamber.
  7. Stop immediately if ink starts to overflow from the fill hole. Draw back the syringe plunger a little so that the excess ink is drawn back into the syringe chamber.
  8. Remove the syringe from the cartridge.
  9. Dry any overflow from around the fill hole.
  10. Repeat steps, as other chambers need refilling. The ink will not leak from the fill holes so there is no need to reseal them.
