UPDATE: I took the cartridge out and noticed there are two big prongs next to the nozzles at each end they go into the little squares of the cartridge. Well the square next to the black nozzle was all red and I had all red all over the large prong and in the square. That is not supposed to be. I looked at an old epson cart. nothing like that no ink spilled everywhere!!! So don't use LD products at least for the PM 260 and I hope my printer is not damaged. Will buy a new epson cartridge and see if it fixes the damage???
