How to refill HP 40 (51640) Cartridges
Step 1. Flip the cartridge upside down, and you will see a black sticker covering a refill hole. Remove the black sticker, and you will see a steel bearing sealing the refill hole. Push the ball down into the cartridge with the supplied accessory. Our accessory may change and looks different than the picture. You can use a small screwdriver do the job too.
Step 2. Insert the needle into the fill hole and inject about 1/2 of the bottle. Slowly inject the rest of the ink or till the cartridge is full.
Step 3. Insert the green rubber plug and seal the refill hole with a push-and-twist action.
Step 4. You can put the cartridge back to the printer, do a head cleaning using printer's built-in function. If the result looks good, skip the rest of the steps. Insert the cartridge into the cartridge holder while still keep the cartridge upside down.
Step 5. Insert syringe into the hole on the end of the holder. Draw the plunger out until 1 ml of ink enters the syringe. Return the cartridge to the upright position. Take the cartridge out and dab any excessive ink around the printhead. Install the cartridge and do a head cleaning. If the print quality is not acceptable, repeat step 4 and 5.

Not a 5 difficulty! Would give it a 3. I watched the video and it came out perfect. I sanded and ran cart under faucet. I used Harbor Freight quick glue. I practiced a few times and used a lot of glue. Let it dry for 1 hour (30 seconds may have been enough) and filled. Made a mess when I used the plunger ( which I don't think was required). Dabbed with paper towel and put in printer. Worked perfect the first time. Really like the clear plastic cover so you can see how much ink in in the cart. Will be ordering more for my wife's printer at work.

BCH offers amazing quality products at very reasonable prices. I ordered the 4 ink 30ml kit and a larger black to refill my #62 HP cartridges. The videos are great and show how to easily refresh these wasteful cartridges and save a bunch of $. Thanks to Kevin and the team at BCH!

4-Color Dye Ink Refill for All Printers - INK ONLY BULK PACK

It was just what we needed. Thanks to your YouTube instruction I was able to order the part and fix my 83 yr old sister's printer. I am an 80 yr old female and was thrilled that this part fixed her printer and saved her some money since she did not have to buy a new printer. I have never before tried to fix something like this. Needless to say, I was surprised it work so well.
