Buying ink as a complete CMYK set is the most convenient way to restock your C3500 across all four colors at once, particularly for production environments where all four tanks are depleted at a similar rate. Individual cartridges are also available if you need to replace a single color between full set orders. Why order from Pacific Barcode: Pacific Barcode is an Epson ProFocus Platinum Partner, the highest tier in Epson’s authorized reseller program. That means you are buying genuine, factory-fresh ink directly from a dealer Epson has vetted for technical expertise and customer support. Your warranty stays intact and your ink is never counterfeit, refilled, or sitting in a warehouse for years before it ships.
