I have to replace the head in my 1400. As far as I have read the head comes with shipping liquid that must be drained and filed with the ink. I understand that Epson has software to preform this task. I am looking to purchase this software. This printer has only 2 voltages that the power supply provides 42 V DC and 3.3 V DC and non of these are adjustable. If you get information on the software pleas share. Oscar Shah.
