Frequently bought together:


Works on both XL and non-XL cartridges.  This is a Do-It-Yourself project.  Watch the instruction videos and read everything on this page before purchase.  

Difficulty Level: 5 (Very Difficult).  

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

  • 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,...
  • Yes, it includes both color and black Covers!  
  • The process involves cutting with a sharp knife and glue things together.
  • This kit should be bought by experienced refillers.  If you are very confident about your skills, watch the video first.
  • 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.  Again, watch the video!

Package content:

  • 1 x Black Cover

  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;

Jerry 05/04/2018

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.

    Totally worth it

    Posted by Ryan on Dec 23rd 2020

    I used gorilla super glue, the one you buy that is sold always half empty for important reasons. I don't like gorilla glue but it worked for this. I still waited 24 hours for drying. I am amazed at how simple it was. Watch the videos and then you will know how to do this. If done right, this is a money saver!

    My Opinion

    Posted by Levi C. Brinkerhoff on Dec 14th 2020

    I would have given it 5 stars if it had written instructions. This is my second order I messed up the first time. Be Very careful. Don't use super glue gel it's to messy and takes too long to bond. I used dollar store instant glue the second time with excellent results

    Wonderful !

    Posted by Patrick Draves on Dec 10th 2020

    What a savings this will be. I can go through a black ink cartridge in just over a week. What a Blessing to be not only able to refill an empty cartridge but to actually see how much ink is left. Who ever come up with this, deserves a raise. Thanks again

    Canon Spongeless

    Posted by Kevin on Aug 13th 2020

    Went together like butter. Did the black first,Primed it and had a small problem with air.Filled it up,primed it again and popped off the plug and the it stopped running out the head.Put it in,Ran a couple of cleaning cycles and it was printing normal. My only tip is to hit up harbor freight for their small one handed hobby clamps. $1.99 and makes holding the pieces together easier.

    Modification Kit For Making Spongeless Cartridge(AS-RFC-CB2CC2)

    Posted by Karl on Jun 8th 2020

    Outstanding! I highly recommend this product. Converted original PG-240(Black) and CL-241(Color) for PIXMA MG_3620 without issues. Follow the video instructions carefully and you will succeed. I purchased this kit along with (KD400X-AC) Premium Dye Ink - 100 ml x 4 Four-Color for Canon. I would buy this conversion kit again should the need arise.
