Epson DX5 heads price rise up day by day from 3 months ago.
There are many printers need Epson heads, especially the F186000. But it is very expensive and hard to buy now. So, there are users buy green connector head (most are Mutoh VJ1604 head and some are Mimaki JV33 head)
It is no problem for single head printers. But if printer have 2 heads or more, it is better use the same head (all DX5 heads or all green connector heads). Because the printing of these two heads are different.
