cartridge. Do not cover or plug the hole you drilled in the sponge compartment. This is the air vent and it must be left open. Remove tape from bottom exit port. Note: If the ball does not make a perfect air tight seal, then ink will drip out of the cartridge at the exit port until empty. If this happens, see step 7.
7.If the cartridge is dripping, let it drip into a cup or dish until it stops. Don't keep the exit area, where the ink comes out in contact with any paper or cloth because it will wick all of the ink out. If it has stopped dripping, put it back in the printer and run a cleaning cycle. If it continues to drip for a long time, you may have an air leak around the rubber ball. Make sure the ball is not damaged or gouged. Put a new one in if it is damaged. If you damaged the ball seat when pushing it in or cut it somehow, it will leak air. If you can't get a good seal with the ball, add some hot melt glue around it to help the sealing process. If you need more of the rubber balls
8.The next time you are ready to refill you can reuse the rubber ball if you carefully spear it from the side and remove it with a bulletin board stick pin. Don't push down on the ball or it will pop into the reservoir area. This is not a problem, it just means you will have to have another ball to seal the hole. If you are careful you can reuse the rubber ball 3 or 4 times.
9.As an alternate procedure you can drill into the reservoir area, inject the ink and then use hot melt glue to seal the hole AIR TIGHT. If you don't like drilling, then try a heated paper clip to melt a hole in the reservoir. Hold it with pliers and heat with a lighter or torch.
If your cartridge drips for a long time after refilling, this means there is an air leak in the reservoir section.
