I have an Epson T562A Black ink conversion kit that says it's for use with a Stylus Pro 7800/9800. I sold my 7800, and this was left behind. To be honest, I am not sure what it is for, but it includes three empty cartridges labeled Cyan, Magenta and Yellow. My guess is that it is for use with B&W only printing.
If anyone can use it, it's theirs for whatever the Post Office charges to ship it.
