There must be a customer for a sale of the iPF9000, could turn out to be a more profitable solution to have him print your 9000 jobs than do it yourself. Image Specialists should have the alternative inks, they cover the 3 brand's pigment printers. Whether the inks keep their properties in time (pigment settling!) as good as OEM inks is doubtful though and that counts if the printer stands often idle.
