Walker I’ve given you all the iaaues and pictures regarding my matt black in 900 ml cartridge which has never worked right. First there was a nib problem that spread matt back all over my wood floor and cost me $100 of dollars diagnose and fix. now the cartridge has lots of ink in it but shows empty. I would be happy if I had a new empty cartridge and a method to transfer the ink of the old cartridge ink into the new cartridge. It is costing you only an empty Cartridge, instruction and a new chip if needed. that is a heck of a deal.
