My experience: in the beginning i made my errors, like plugging the wrong vent, then it was optimal color printing. Suddenly i miss all the welfare: way-too-dark, like large gamma error, color crush like film '300', picture not usable at all. Interesting for investigation: it happen while testing QTRgui and trying to normalize output, with good results using the CC-K3V inkset and B&W pictures. Switching back to color the wrong print appeared. Another point, i never switch ink nor paper, always stick to PK/glossy BUT suddenly, together with the error i noticed the MK cartridge no more full but 4/5. How? QTRgui uses MK without warning and ink swap procedure?
Notice that i made all in my mind to check the trouble: re-installing the Epson Win 7 driver (6.75), printing with Epson ICM, with LR4 ICM, PS6 ICM, with Epson Adobe1998, with no ICC at all, checking the cartridges damper, using another laptop with Win8: same result all over (or slight minimal variation). Another point, if printing without ANY color correction (no-Epson, no-windows app) the result is slightly better, but really little difference at all. It looks like a conspiracy made by EPS-MS to protect the ink/paper business. Ops.. paper! i notice someone yelling on paper for inkjet with sustained propaganda, well.. in the beginning i stop searching for big names only, then i saw that Axxxy makes 250g and 300g glossy A4 and A3 at a very interesting price and no difference in output, but may be i am wrong as my R3000 is no more stable Any further action? Any suggestion? Anyone knows how to read the internals of the printer, to check any wrong parameter or how to reset it to a safe default?
