Epson R300

I have an Epson r300 that won’t print four out of the six colors. I blamed it on the generic ink cartridges I had (Lite Cyan, Magentas and Yellow), although the Black and Cyan are fine. I performed Head cleaning, resetting, I purchased new Epson cartridges and replaced but it still won’t work. Any chance to get it back?. I like its CD printing feature.
