Konica Minolta C500 Pro Printing Problem

[konicac500]

Dear Friends
I have a problem on printing.

When i am printing full colors on a page, the color it's not clean.
and the letters, on paper are not "clean".

Only if i print 100% black it's perfect.
I clean drums, transfer belt, but nothing.
And i have lines on photos.
Example: if i print letters on white paper and have 100% black it's perfect.
If i print, letters with 30% cyan and 40% magenta are not "clean".

Please someone to help me

Thanks

try an internal test print. (from the print engine only,not the controler)
