I purchased an Epson WF 7840. I would like to use it with refillable ink cartridges. I need to print Cad drawings. I am unsure whether to use pigmented and non-dye ink from Inktec like E0013 or Octopus or fill the cartridges by purchasing bottles Epson 113 Ecotank ink? Thank you

I would expect that all inks which you mention will print, differences may exist in the the achievable black level but I'm not aware of any test to compare the black level of these inks so you may test some of these in this respect which ink would deliver you the best contrast and sharpness of your prints.

I have the same printer: use pigment ink. The original cartridge are pigment ink too. I am using Inktec pigment ink these printers, but you can certainly use Epson ecotank 113 bottled pigment ink of your choice. Be sure all colours are pigment.

I would use only Epson 113 ink. I only refill original catridges
