I always use original cartridges in my Epson printers - the ones supplied with the printer when new. Unlike some, I have never had a problem with compatible cartridges. At one time I refilled them myself, but it is too much hassle when you look at the price of compatible cartridges for Epsons these days, so I have given up and my drawer is still full of ink bottles, chip resetter and various hypodermic syringes.
If S.D. will permit me, I always go to
