I just received 2 new Cone refillable cartridges today. However, upon filling the Light Magenta and inserting it into the printer, I got the dreaded error message: “Printer does not recognize the following cartridges:”
On the printer screen, there was an ‘X’ through not only the Light Magenta, but the Yellow and Light Cyan, as well (those second two are both Epson factory carts). So, I put the old Epson Light Magenta back in, and all carts were again recognized (though the old Epson LM still showed empty). However, when I put the Cone LM back in, I again got the error message, with those same 3 carts X-ed out.
From what I have read on this forum, the problem is likely a dead battery, in the Cone LM cart. The cart though, is brand new—just out of the box. The date on the box is “February 2014”, a full year ago.
