Have bought a Chipresetter for 15 (deceives the PC before full ink cartridges, so that even the last remaining ink will be used up). Whenever a cartridge causing problems, I try to Chipresetter (sometimes several times) from - so far I have brought each cartridge up and running (Epson Stylus SX 435W). One should only regular print and sometimes clean the printheads (manually! Not with the automatic cleaning). The replacement inks tend otherwise to constipation.
