Canon BCI21 BCI24 Refill Instructions
Place the cartridge on its side onto a level surface.
Assemble the needle and syringe and fill with 4cc of the desired colour ink.
Make sure you fill the correct colour chamber with the correct colour ink.
Holding the needle over the sponge material of the outlet hole, very slowly apply pressure on the syringe.
Allow a few drops of the ink to drop onto the sponge, allow the sponge to absorb the ink.
Important- DO NOT TOUCH THE SPONGE, OR ALLOW THE NEEDLE TO PIERCE THE SPONGE.
Repeat this process until each chamber is full.
When the chamber is full the sponge will no longer absorb ink.
Allow the cartridge to stand for a few minutes then return the cartridge to the printer.
Run a cleaning/priming cycle as per your printer instructions
