How to Refill a Black Canon Ink Cartridge 210
- 1). Set the Canon 210 cartridge over some paper towels or newspaper to absorb any spilled ink.
- 2). Remove the top label to expose the vent hole in the middle of the top of the cartridge.
- 3). Drill a hole through the vent hole with the 1/16th inch drill bit. The vent hole is in the center of the top of the cartridge in the middle of a small dimple.
- 4). Fill a syringe with 15 ml of black refill ink. Insert the needle of the syringe into the drilled hole.
- 5). Slowly inject the ink into the cartridge ink chamber.
- 6). Replace the cartridge into the Canon printer. Let the cartridge sit for at least eight hours so the new ink can saturate the internal sponge.
