CANON BC-21/24 Black Refill Instruction

1. The cap on the top of the cartridge must be removed. Hold the cartridge with the label facing you.

    Insert the blade of the knife where the cap meets the cartridge and twist to pop off the cap.

    Be careful not to break the finger on the back of the cartridge. This finger holds the cartridge into the print head.

2. Once the cap is off you will see a hole. The 3 larger holes are not fill holes.

    The small hole in the center of the cartridge is the fill hole.

    In order to inject the ink you must first enlarge the fill hole using an awl.

3. Inject the cartridge with up to 8 ml. of ink when empty. Insert the needle into the top part of the inside sponge.

    Inject S-L-O-W-L-Y to fill the entire cartridge. In the meanwhile, watch the outlet hole and stop filling

    once any trace of ink coming out is observed (if happened, draw back a little). Tape back the cap.

4. Set the cartridge on a paper towel for 30 minutes as a drip precaution, then install the cartridge to make a test print.

5. Clean the syringe with water and dry for future use.

* Refill immediately once cartridge empty.
