Yes, they can be refilled. These cartridges come with a chip that tells the printer the cartridge is a genuine Canon, so the printer accepts it and reads the ink levels. This chip must be reset in order for you use the printer without ruining your warranty. We at InkjetReset.com a green company now have resetters in stock that will reset this chip to its original specifications, so when you refill the cart, your printer will accept it, and your printer monitor will keep you aware of ink levels. The cost for a resetter at this writing is $32 including a 6 month replacement warranty.
To refill, avoid drilling a hole, Peel back the label (top front of cartridge) and you’ll see the original fill hole. Using fingernails or pin, pull that plug & refill. Use silicone (window sealant) to seal the hole. Silicone is easily removed when you refill again.
We stock ink and more for cli-221, pgi-220, cli-8, pgi-5 Canon printers. See the video on resetting at: inkjetreset.blogspot.com
