REFILL INK CARTRIDGES CANON BJI-201BK HC, BJI-201BK, BJI-201C, BJI-201M, BJI-201Y

With the cartridge upside down, using a screwdriver, push in the ball bearing that seals the filling hole. NOTE: There are several versions of these cartridges. One version has the filling hole under the label on the top of the cartridge. Another version does not have a ball bearing at all. In this case it would be necessary to make a hole for the needle to be inserted. Make this hole in the same spot where the ball bearing would be located, as shown below. Seal hole with the plug provided.
Connect the needle to the syringe and fill with ink.
Inject about 5 ml. of ink into the filling hole until the tank is full.
Use the included plug to seal the filling hole, make sure that the plug is sitting flush in the cartridge. Additional Note: If the cartridge has been empty/dry, the sponge will no longer accept any ink which will cause the cartridge to leak.
Rinse the syringe with water and dry for future use, or use with a different color ink.
Reinsert the cartridge and run a priming cycle as per printer instructions
