As previously Posted I'm having issues with my Printer being selective.. I'm trying out my Son's printer which is an Epson WF3720 model .. Curious my Printer only has 2 Ink Cartridges (1 Black, 1 Color) The Epson has 4 Ink Cartridges (1 Black, 3 color tones) If the Color is empty do you replace all 3 color cartridges together ??
