Rob, the product description on what you bought is
“The EPSON 1400 is a little sub $200 gem in the EPSON printer line-up. EPSON developed this Claria ink printer for non-archival printing - using a simple six ink design. But they gave it the highest printer technology by giving it a 1.5 picoliter drop size so that it can do with six inks what other printers require seven or more. This is a true photo quality printer which produces what Epson calls “awe-inspiring images” that enable photographers to “realize the full potential of todays newer DSLRs.” The only thing it is missing is archival inks. So, we stepped up to the plate with a refillable cartridge system running our ConeColor K3 deep color gamut pigment inks. You will need color management. You can either provide your own with a device like the ColorMunki or download our free library of professionally made ICC profiles from the ConeColor website by clicking here.”
So, if your intention was to use the product as designed you have bought the right ink for your printer, but are not using it correctly. You should not mix the two ink types together (dye and pigment). And you MUST use color management (ICC profiles).
If on the other hand, you just wanted replacement inks that are also dye based and similar to the Claria color gamut - then you bought the wrong ink. We are releasing a dye based ink product called InkThrift CL for Claria ink printers. But - we are not yet released on that.
