Need help with my SC-500

[prettybird]

OK, I got the profiles installed to the output profile area.  And I tried printing a photograph using the settings that you said you used (neron) and for output profile I used both the PGVP super and PGVP fine setting and they both still look bad.  It looks like the colors are printing right, but it still looks really grainy (like there is not enough ink or like it's a low quality photo that I tried to enlarge way too big.  I took the photo using 8 mega pixels and I'm only printing it at about 5"x3".  Is there some other settings I should adjust still?  Should I have color correction checked or unchecked?  If checked, how should I set the color settings? 

Thanks a lot for your help!
