HP 51629A and 51629G Cartridge

Refill Instructions

Step 1) Put the cartridge on some paper towels in an area where you can tolerate a spill.

Step 2) Tape over the bottom maze-like hole and the top center hole. Be sure that the top center hole seal is particularly air tight. Use black electrical tape -- not scotch tape or masking tape, since these are not air tight.

Step 3) HP has made two types of 51629A cartridge. Some have a top corner hole and some do not. Look for the top corner hole, which has a white plastic bead plugging it. (Many newer cartridges don't have such a hole.)

Step 4) If your cartridge has a hole, push the ball in the top corner hole into the cartridge with a ball point pen or similar device. Never insert anything sharp into the top center hole! We sell replacement beads.

If your cartridge does not have a corner hole, point the arrow toward you. On the top surface of the cartridge in the left rear corner, drill a 1/16 inch (1.5 mm) hole. If you don't have a drill, you may melt a hole by unfolding a large metal paper clip, heating one end with a lighter and melting a hole into the plastic cartridge. Be careful not to burn your fingers with the paper clip or the lighter!

Do not push the drill bit or paper clip deep into the cartridge, since you may snag the bag and cause an irreparable leak!

Step 5) Inject about 40 ml of the ink into the top corner hole.

Step 6) Now you must seal the top corner hole air tight.

If your cartridge came with a top corner hole, we suggest using a plastic bead to reseal the hole. Or, you may use hot glue, hot wax, or silicone rubber.

If you had to drill or melt a hole, we suggest using hot wax or hot glue, or silicone rubber.

Step 6) Now you must seal the top corner hole air tight. We suggest using hot wax or hot glue, or a plastic bead. Black electrical tape will often work. Whichever you decide to use, you should squeeze the cartridge just before sealing to set up the vacuum.

Step 7) Remove the tape.

Step 8) Set on a paper towel for an hour as a drip precaution. Expect a few drips until the vacuum stabilizes.

If it does not stabilize within an hour or so, take the cartridge, turn it upside down, take the needle off the syringe bottle and use the bottle to blow air into the (formerly top) center hole. Then set aside the cartridge to stabilize.

Troubleshooting a Leak

1. If you stick something sharp into the top center hole, the cartridge will leak forever.
2. If the seal applied to the fill hole is not air-tight, the cartridge will leak. Be sure not to use scotch tape or masking tape, since neither are air-tight.
3. If you have a leak around the bottom maze-like hole, this may be able to be fixed with some glue. These leaks can be caused by a crack in the plastic around the hole, or caused by a rip in the interior bag.
4. If you have ripped or punctured the interior bag, the cartridge will leak forever.
