Second Locked DX5 with First Locked Decoder

I recently purchased a secondhand UV flatbed printer from China (BrotherJet BR-U7880) and am currently experiencing some issues with it. The printhead moves side to side, but does not fire ink. I cleaned the printhead, but it didn't fix the issue. I did some research and concluded the printhead I have is a perhaps a second-time locked Epson DX5, and the decoder board is first-time locked. Does anyone know if this is expected behavior for this pairing of printhead and decoder. I want to be sure all the other parts of the printer are functional, and it's only these 2 components that need replacing. I've attached pictures of the printhead circuit board and decoder board. Also if I'm incorrect in my conclusion about this printhead being second-time locked, please let me know!

Thanks!
