Changing ink color in a 3800 cartridge

Is there a procedure to change the ink color in a 3800 cartridge?

Follow the installation procedures for the 3800 / 3880 here. Be aware that if you are installing the Digital Negative ink system that you must follow the ink placement order in the NEW Piezography manual.

We do not recommend using a different ink in a previously used 3800 cartridge, because they can not be totally cleaned/dried, and any residual ink or water will contaminate the new ink.
