Canon: BC-01, BC-02 (Also Apple M8052GA, M8041GA, and M4609GA Cartridges.)

Many different Canon and Apple Stylewriter Printers
There are two different types of these cartridges. The older type has a single vent hole and the newer type has two vent holes.

DOUBLE HOLE MODEL
Locate the refill plug (top right of the cartridge). Using the eyelet screw provided twist it into the vent hole 3 or 4 times and pull the plug out. You are now ready to refill the cartridge. Place the cartridge on several layers of newspapers. Inject up to 20cc of black ink into the cartridge. Pause occasionally and let the sponge soak up the ink. The cartridge may not take all the ink since it may not be totally empty.

SINGLE HOLE MODEL
Locate the refill plug (top right of the cartridge) . Enlarge the vent hole using the 1/16" thumb drill provided. Place the cartridge on several layers of newspapers. Inject up to 20cc of black ink into the cartridge. Pause occasionally and let the sponge soak up the ink. The cartridge may not take all the ink since it may not be totally empty.

Set on a paper towel for an hour as a drip precaution. Don't allow the printhead to touch the paper towel or all of the ink will be drawn out. Expect a few drips -- If it doesn't drip, the ink is not ready to print. It is not necessary to seal the hole except during long storage and transportation.

Replace the cartridge and run 1 - 3 cleaning cycles as per printer instructions.
