Hi all, I am new on this forum and I need help with my Roland VS 540. I purchased it used and it had ink config. CMYKLCLMWM.. I want to change it to double CMYK. I changed ink lines, head .... and it is ready as new printer. The problem i have is in ink menu does not have eco sol max2 ink... it has ecosol max 4c, ecosol max3 4c but does not have ecosol max2 4c. When i searched web the roland is saying that 4.80 firmware is to upgrade from ecosol max to ecosol max 2... my is already on firmware 5.3, so my gues is the firware problem. Is there a way to downgrade firmware?
