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.
