We are not a reseller for Epson at this time. We are merely testing the equipment and have been for some time. All they gave me is the "list price" for each bag of toner which is what I posted. I would assume CPC would be calculated the same way as a toner based machine. Based on my evaluation we would not be a reseller of the current machine and would wait until a page-wide array machine would come out to consider. The 24ppm is not accurate when printing high quality documents.
