Epson ET-8550 Bronzing?

[Ink stained Fingers]

if I was going to buy the ET-18100, would be to replace the 107 black ink with the T54C?

That could be an option - you just would need to swap the bottle tops

That's just me thinking out aloud.
As I said before, I'm not going to give Epson £700.00 for a printer that uses inferior inks.
