Refill Your Printer Cartridge





Introduction: Refill Your Printer Cartridge

About: I am studying electronics engineering (undergraduate)

Printer Cartridges are surprisingly costly. As an alternative, you can get it refilled at a store. The cheapest and effective alternative though is to refill it yourself. All it takes is a bottle of printer-ink and a syringe.

Step 1: What You Need

1. Printer-ink. You can buy it from a computer store. In Bangalore, you can buy it from an ink-refill shop at the entrance of SP Road, near City market.
2. A 1ml disposable syringe. The smaller the needle, the better.
3. Your printer cartridge. My printer uses a HP56 cartridge. But the refill method is same for most inkjet cartridges.

Step 2: The Cartridge

There is a black spot on the white-sticker covering the top-cover of the cartridge. Underneath the black spot is a hole through which ink can be injected into the cartridge. You can peel off the sticker to locate the hole. Or simply pierce the black spot with a needle ( as shown in the figure ).

Step 3: Refill Your Printer Cartridge

Draw ink into the syringe slowly and inject it into the hole. That's it!
Some important tips:
1. The needle size is very small. If you draw ink into the syringe too quickly, you can create air-gaps. Air gaps can block your ink cartridge. So make sure that there are no air bubbles, before you inject ink through the hole.
2. Refilling is a messy job. Make sure you have a piece of paper/waste cloth. The image has a clean background only to make it look good!
3. I was advised to fill the cartridge to near-capacity and not full. i.e., my cartridge's capacity is 19ml. So I filled it to about 13ml. Probably this is to prevent leakage.
4. Once, the cartridge is filled, it should be allowed to set for a few hours. This lets the ink to settle at the bottom of the sponge. The sponge is located inside the cartridge & cannot be seen.

P.S. Sorry for the poor image quality in this instructable. I ruined it by putting the camera too close to the objects.

Acknowledgement: I was "taught" to fill ink by my neighbor Sridhar. Thanks very much!

Does this article apply only to HP ink cartridges? My Brother cartridges appear to be a whole different trip.

Do you think you could use homemade ink for this? I'm wanting to use eco-friendly ink for my business labels.

get a chip resetter for your cartridgers

your cardridge has a chip built into it that tells the pc that the cardridge is full so its not that easy for people to refill their cardridges, that resetter will erase the memory and reset it on that chip

Can you be more specific about the size of the syringe? what size ml and needle?

just ask a chemist to give insulin syringe. I know it very well as my grandmother uses the same thing

Should i need to push the syringe needle into the sponge or the needle should be above the sponge,while refilling it with ink?

You can fill 15 ml ink into this cartridge. Always use pigment ink for this cartridge. I used inkclub brand ink bought from snapdeal & it worked fine. After refilling use a suction tool to make the ink flow from sponge to the printer head. Check it on tissue paper & install it in the printer. Happy printing!!!!

I got some oil-based printing press ink the other day.
Would this ink work???

BTW, where do you buy syringes?

sir,i am also studying enginearing,i have a dout,my email id id,please send me ur contact number,i will call u,i am in bangalore

I tried that with my HP cartridge and regular ink I bough from Office Depot but it didn't work out. Is it because the ink is not thick? Is the ink different than the other inks? Thanks.

Your cartridge did not work because you did not get the ink to flow down to the piezo pumps.
The way the cartridge works is this:
The bulk of the ink is sitting in a sponge and this sponge sits on a slightly-permeable membrane that only allows it to drip though the pores.
The space under the membrane must be filled with ink and the ink must reach each of the piezo pumps.
When a pump is activated, it squirts a microscopic amount of ink onto the page to form a dot and this action draws more ink through the channel and draws ink through the membrane, from the sponge.
When the cartridge runs out of ink, the channels to the pumps run dry and by merely filling the sponge with ink, will not re-start the ink-flow.
What you have to do is remove the lid, fill the square with a small amount of ink and get the rubber from an eye dropper and sit it against the pumps (the micro holes) and draw the ink through the membrane to the pumps.
You can also remove the sponge and fill the square with ink and replace the sponge. This will push some ink through the membrane and gradually get the ink to the pumps.
In addition, you can flick the cartridge very sharply in an attempt to flow the ink through the membrane and through the channels to the pumps.
This all boils down to one thing.
The ink must be at the piezo pumps so that more ink can be drawn to the pumps as each dot is produced.
The cartridge works on a “drawing motion” or “sucking motion” and this has never been explained before.
You must have ink at the “head” to draw more ink to the head.

Well, if you have used printer ink, there shouldn't be any problems.

In particular, did you allow the ink to set for a few hours ? Also, your HP printer software will invariably have features like: printing a test page, Clean your print cartridge etc. Try those

Further, What is your printer model, particularly the cartridge (number) ? Because as LasVegas has said (see below), some cartridges come with "smart chips" that tell the printer when the cartridge is empty. In such a case, simply refilling the cartridge wont help. If the chip is reset, then it will work. I have no experience with resetting :(

Try googling it!

I don't think that was a printer ink, I just grabbed refill ink from office depot and that was all they had. The cartridge is HP56 which is the exact one shown above. Printer is psc 1210 xi. I ordered a kit from ebay that is supposed to work as printer refill ink, item # 260185507269 and I am still waiting for the shipment to arrive. I will try it again with that ink and see what happens. I am shopping for a printer but haven't decided which one yet, I would like to buy one that is easily refilled. BTW, when I taped the chips with electric tape the printer didn't read that there was any cartridge installed.

I like this , but now i prefer remanufactured inkjet cartridges that are the same refilled inkjet cartridges but the refilling is done by professionals in their labs or workshops etc. and you do not have to get ino the mess of ink and anything. They also are very cheap as compared to other printer cartridges.
