Hi GregK! I have MIMAKI JFX-1631, the original head is (replacing M008386 & KX-CE308644CS-CE4 number M018821, but I want to install Toshiba CE4W1 (Ref. CE4W1 - DP part: PPHTO87940), it is three times cheaper. I read the characteristics of the head - the same. Has anyone tried? Will it work well or will there be problems? Thank!
