Replacing a Canon cartridge can be expensive. If you have a color printer, you have to spend a lot on ink. Most Canon cartridges are refillable, so you can save a lot by refilling them yourself. To refill Canon cartridges at home, you will need to purchase a refill kit.
Steps

Step 1. Make sure the cartridge is empty
- Most Canon printer cartridges contain an electronic device that counts down with each character printed.
- When this number drops to zero, an error message will appear on the printer.

Step 2. Follow the manufacturer's instructions to remove the cartridge from the printer

Step 3. Check if the ink tank is empty
If there is still ink in the tank, replace it, and if you get the error again, press the OK key to continue printing

Step 4. If the cartridge is empty, refill it with ink
Method 2 of 4: Refill the cartridge

Step 1. Buy a refill kit from a computer supply or office supply store, or order it online

Method 3 of 4: Replacing the ink

Step 1. Find the hole where the ink comes out
It is where the sponge is located.

Step 3. Cover this hole with duct tape to prevent ink from leaking out of the cartridge when refilling

Step 4. Take a drill, insert the smallest drill bit and drill a small hole in the cartridge under the sticker
- Look for the letter for the ink color on the cartridge. There is a circle with a depression under it.
- If you want to refill a cartridge, drill a hole right in the center of this recess.

Step 5. Insert the needle into the punched hole and gently squeeze out the ink
Watch the cartridge while refilling to avoid spilling too much ink.

Step 6. Remove the needle from the cartridge, remove it from the syringe and place it in the sink to avoid accidentally getting inked

Step 7. When you are finished refilling the cartridge, seal the hole you made with glue, hot wax, or tape to prevent ink from leaking out of the cartridge

Step 8. Peel off the tape you used to seal the hole above the sponge
