I didn't say there weren't any CIS for an Epson 7610 or any other printer for that matter. What I did say was that none are recommended, as you have found out. I still think that using an inkjet printer to do the volume work that you appear to be doing is grossly false economy but that is up to you. The only cartridges that Epson, or any other printer manufacturer for that matter, recommend are their own brands which are stupidly expensive. Epson, as far as I am aware, do not make a CIS for any of their printers and neither do any other manufacturers, as far as I am aware, therefore you are limited to third party suppliers and all the manufacturers do not recommend third party inks. Anyway your obviously hell bent on using an inkjet to do what you want to so I am out of here. hopefully someone else can help.
