Refilling Canon BCI-3 / BCI-6 Cartridges

Many people report problems when refilling these cartridges. This article is a email from a customer explaining how he refills these cartridges with a near 100% success rate. Note the BCI-3 and BCI-6 cartridges are physically identical and refill the same way.

First: I put a piece of electrical tape over the ink outlet.

Second :I drill a hole just large enough to except the needle.

Third: I fill the cartridge with the ink.

Fourth: I put a piece of electrical tape over the fill whole I drilled and leave the tape on the ink outlet hole till your ready to use it.

Fifth: Remove the tape on the ink outlet & install in printer.

Sixth: When cartridge shows empty, put a piece of electrical  tape over the ink outlet hole so it will not dry out and do not remove the tape over the fill hole. I have waited a week to refill the cartridges using this method. When ready to refill, remove tape over fill hole, fill cartridge, and re-tape with new
piece of tape, (do not use the old piece as it will leak if you do).

Seventh: Always use fresh tape (top and bottom of cartridge), every time you
refill. I do not even use plastic gloves anymore when using this method of
refilling.

Hope this can help your customers who use your refill kits.
