I am using "ink mil" ink cartridge and it is very pricey. I do have bulk ink system which I can reinstall to the printer. Does any one know the way to break the code system so I don't have to use cards. I have heard that there is a way out there where no card neccessory to use with bulk ink system. Also which brand solvent ink is good for bulk ink system. What toy I should use for recharging cartridge cards. Please advise. Any help will much appreciated.
