What are compatible printheads for L1800?

[atlix211]

My Chinese L1800’s printhead clogged and I can’t find L1800 printheads where I live (Japan). The seller also refuses to send replacement parts despite the description saying it has warranty. 

I bought some online and all of them are refurbished and does not even work. I then decided to look up used printers and I found a similar printer, an EP-4004 or also known as 1500W in the US.

Does anyone know if it’s compatible to use with L1800? Or other models that are also compatible? Thanks in advance. 

I might be able to find Japanese counterparts.
