It sounds like the yellow ink (and maybe some other colour) is not getting through the ink delivery system because it's blocked by dried-up ink. This can happen if all the colours are not used regularly, ideally every couple of days.
Try using the cleaning process in the Lexmark printer driver, and if that doesn't work you may need to use cleaning cartridges which contain solvent instead of ink. However, whilst these are readily available online for Canon, HP & Epson printers, not so easy to find for Lexmark models.
In extreme cases, even they won't shift the blockage & the printer has to be scrapped, as happened to me a few years ago with my Epson.
