I have the ESP 3 Kodak printer, and I recently put new ink cartridges in. When I did this, the message "Black and color ink cartridges not installed" came up. I went to the help section of their website, but nothing there helped the problem - they suggested taking the printhead and cartridges out and in again.
I put the old cartridges back in, and it said they were low on ink and I needed to replace them. I did that and this message of ink cartridges not installed came up again.
