Hope is not late for answering.
My experience is: confused.
My R3000 prints like woman feeling, sometimes bad with no hope to revert to good, sometimes good. Well, in both cases the workflow changes itself from bad to good without any apparent reason. Sometimes fingering Epson driver 6.75 ICM settings back and forth, sometimes changing paper orientation. It is a woman. I gave up finding a reason, I live with her, R3000, now I know some that prints are dark, contrasted like double color managed besides is not (absurd application and driver cannot speak each other and adjust accordingly) and put all this matter of acid into the Windows bin: its a problem from OS, similar 'sticky' malfunctions are common with other application. Wizards at Adobe, MS,Epson etc, etc, should know well this behavior but they are too busy with last version upgrade, porting code from one to another. IT is young but looks like an obsolescent science, maybe time is passing quickly and there is no real innovation, apart greenish translucent buttons. As part of my living I always check the preview in Epson driver to lessen the paper/ink waste, even so R3000 can print bad, sometimes. Best wishes.
