Now it has both Black and Color Covers!

Difficulty Level: 5 (Very Difficult).  

This kit can make a pair of  SPONGELESS Refillable Cartridge for ALL Canon integrated Cartridges.  

Different regions will have different names for the same cartridge.  For example, we will call it PG-240, CL-241.

South Asia will call it PG-840 CL-841 (use 8* instead of 2*)

European will call it PG-540, CL-541.(use 5* instead of 2*)

India will call it PG-740, CL-741 (use 7* instead of 2*)

Same thing as PG-845, CL-846 (same as PG-245, CL-246 in US and Canada).  So this kit will work on all those 8's, 5's, 4's,...


An integrated cartridge is a cartridge and printhead built into one unit.  Canon uses different model numbers across sales regions.  For example, PG-245 becomes PG-645 in Australia and PG-445 in the Philippines.  If the cartridge has a ribbon and a printhead, then this kit is compatible.

We will list a few compatible models as examples: PG-210, CL-211, PG-240, CL-241, PG-243, CL-244, PG-245, CL-246, PG-440, CL-441, PG-445, CL-446, PG-540, CL-541, PG-545, CL-546.  

  • Yes, it includes both color and black Covers!  We started at black and then added the color cover to this kit. 
  • The process involves cutting with a sharp knife and glue things together. This kit should be bought by experienced refillers.
  • This is a Level-5 Project.  Please read our Beta Tester's Tip before proceeding.  The unit is shipped without ink.


The black cover can be installed backward.  If you install it backward, it won't fit in your printer anymore.  Please take a look of this picture: you should have 3 notches on the top, one long bar on the bottom and an arrow on the left side to tell which side should be up.

Package content:


  • 1 x Black Cover
  • 1 x Color Cover
  • 1 x Priming Syringe

  1. Use a piece of saran wrap to cover up the printhead.
  2.  Find the seam between the cartridge and cover. Put the cartridge on the table and push the knife down on the seam. Use the middle of the knife as a pivot, tilt the blade up and down, work your way gradually and cut off the cover. The cover should come off quickly.
  3. Remove the sponge. Use the sandpaper to make the cartridge wall even on the top. You will need to glue this wall airtight to the new cover.
  4.  You can wipe off the dust with paper towel. Or, wash the cartridge under hot water. There will be dust inside the cartridge if you do not remove it. The filter will stop the dust, but it is a good idea to wash it and have a clean cartridge.
  5. Apply glue and put on the new cover. Before applying glue, do some dry-runs. The new cover's shape is a little different than original Canon's cover. Point the narrower side towards the top, which is the side with electronic ribbon. Apply a layer of super glue evenly. Make sure the super glue covers the entire width of the wall. When the super glue is dry, it has to form an airtight bond. Install the cover. You can put the cartridge upside down and push some pressure on it, or use a clamp.
  6. Wait 12 hours and fill up with ink. Unplug the black plug, and fill it up with ink. The original Canon uses 7 ml of ink. Now the spongeless cartridge can take 20 ml of ink quickly. You can fill it all the way to the top, or leave a little room for the plug. Clean the electronic ribbon.
  7.  For the first time usage, we need to remove air bubbles from the bottom of the printhead. Use the flat priming syringe, blow up to 1 ml of air into the air hole, which is the little hole on top of black refill plug. Ink should run down from the cartridge. Use a paper towel to dab and absorb the excessive ink. Do not rub the printhead with a paper towel. A gentle pat is enough. This method is also useful to remove clogging in the future. Put the cartridge in the printer and enjoy printing.
  8.  Turn off the ink gauge. The printer's ink indicator will not be accurate for refilled cartridges. Eventually, you will see the cartridge's LED light flashing; printer stops printing and claims there is no ink in the cartridge. Do not cancel the print, just press and hold the Stop button, which is a triangle sign. Hold it for 5 to 10 seconds, the printer will be back to work and will not track your cartridge's ink level anymore. You need to keep an eye on the print quality. In our experience, one refill lasts about 500 pages. Once you see the printout missing color, you can take the cartridge out and refill it. The printer will no longer bother you about ink level, and the cartridge lasts almost forever.


Package content: 

1 x Black Cartridge cover, with air pressure assembly and a black refill plug. 
1 x Color Cartridge cover with air pressure regulator and color refill plugs
1 x Flat-head priming syringe with a silicone tip.

Things you will need (not included in the package):

1. a working cartridge. 
2. A 150 grit sandpaper, or a cement surface, like garage floor or driveway. 
3. Super glue (e.g., Scotch or Gorilla). If you use Gorilla glue, use the clear glue with a white bottle. Do not use the brown type.
4. Some saran wraps. 
5. A box cutter (utility knife)
5. Black ink. We suggest black dye ink for Canon (example)


Beta Reviewer's Tip;

I recently converted a couple of Canon cartridges using your clear plastic lids. I've been printing for a while and noticed the printer started skipping a little. Checking I saw the black level was down to the filter level so I popped the corks and refilled both cartridges. Working perfectly again. Well done guys!

BTW, I used the GEL super glue, fills in cracks better and doesn't drip as much.

Reviewer 07/10/2016

It works great!  I had a decision if I want to wipe the excessive black ink with a paper towel, risk the fiber clogging the printhead, or just leave it on the cartridge.  I left it on, and the first few pages had ink dripping on them.  The priming syringe is a great tool to unclog the printhead.  I guess I won't need my clip from InkTec anymore.  Also, make sure you have enough superglue.  I bought mine from a 99c store.  I am glad that I bought two of them.  By the way, I was using BCH pigment ink.


Justin 07/19/2016:

Well, my problem was the fact I was watching the video and pausing at the same time. Well, it got to the super glue part, I paused it, went and bought super glue, glued it on, waited 60 seconds for the glue to set up. 
Well, I filled it up and realized that it said to wait 12 hours for dry time. So what happened is when I injected air into the cartridge it came out the side where I had glued it. I just put more glue on the sides and 
stuff and let it dry and then it was fine.

I honestly began to wonder if it would work because my printer started saying it did not recognize the cartridge and that was prior to me even getting your package in the mail. But, it works now and we will see how it goes. I honestly thought directions were pretty simple as long as 
people don't do like me and pause it and maybe watch it once through the entire thing, then go back and do it step by step


Update from Justin  4/17/2018

I just wanted to get back to you to let you know the ink is doing great so far and I ended up being able to print over 2500 pages with the black color before the cartridge itself give out. I ended up having to get another printer anyway so transferred the modifications over to the new one.

    This works great. Just be careful with the color cartridge. I broke it trying to pull it apart after I didn't get it glued properly. I shouldn't have started with the hardest one first. The black ink was easy and prints perfectly. I purchased a second kit to fix the color cartridge.

    Best thing ever!

    Posted by Dan on Oct 26th 2018

    This is an easier mod for printer carts vs drilling them out for refills. I did this in about 15 minutes and it works great!!! you will need to prime your print heads afterwards!!!

    Not so hard. Used gel super glue. Perfect seal.

    Buying second set

    Posted by Jerry on Sep 23rd 2018

    The refill covers have been working very well but I feel I should get a second set for when one of my cartridges dies.

    I think I can reused the old covers but spares makes me feel better. The printer is used for business (invoices, instruction manuals) so we can't be down for long.

    Amazing product, super easy to do.

    Posted by Daisy on Jul 21st 2018

    I purchased the covers and couldn’t believe how easy was to do it as on here it says very difficult but is easier than expected.

    I love this invention, used to buy other refill kits and those are very messy, drilling the wholes was hard, of course didn’t have the option to make it spongeless untill now.

    Very happy with the product and more happy about saving on ink because what comes from the manufacturer is ridiculous, seems like they only put a few drops of ink to keep you buying more every month. Good job guys!

    Awesome product

    Posted by Daisy on Jul 20th 2018

    Just wanted to say what a great invention you made with the refill kit covers. Long ago I used to get the refill ink but was messy and trying to drill the holes wasn’t easy. Wish I made a video because is so easy and works great too. More people need to know about your product.

    Good, then leaky, then clogged?

    Posted by Philip on Apr 28th 2018

    I modified a PG-245 and a CL-246 to use with an MX-492 printer. The modified cartridges worked at first, but after a few weeks, blobs of ink were found on my printed pages. I added caulking around the cartridges in case the super glue didn't seal well enough. That did not fix the problem. More than two months after the modification, my black ink cartridge seems to be clogged.
