1. The filler holes of the cartridge are located under the top. Remove the top before refilling by carefully prying it off
2. Cover the other two holes with tape while filling one. This will prevent cross contamination.
It's also a good idea to check the color chambers with a tooth pick before putting in ink. The chambers are somewhat dry and you might have to push the tooth pick in far to get ink on it.
3. Insert the filling needle into the filler hole of the color to be refilled. Slowly inject up to 8ml. of ink until the sponge is saturated.
Important: When you take off the color cartridge cap you will notice that the sponge is white. Do not change the sponge color. Fill the individual colors until the color just begins to show in the white sponge.
5. After refilling the top can be put back on with scotch tape.
6. Replace the cartridge and run 1 - 3 cleaning cycles as per printer instructions.
Or print the following cleaning page: Cleaning Page for Color Cartridge
If necessary leave cartridge in printer for up to 24 hours. (Allows ink to pass through internal sponge to the print head).
The photo cartridge is filled the same way as the regular color cartridge.
For best results empty cartridges should be refilled immediately.
Also this work is done best over the sink.
