Like others with the Epson R3000, I have had smears and head-strikes with some thick papers. I have reduced the incidence of such problems by using additional support in the output tray to keep the paper as flat as possible exiting the printer. I tried to make a print on a sheet of Canson Platine from a sample pack. I used the manual feed tray (front). To be safe (I thought), I set the platen to wide and the paper thickness to .6. Two areas of the print, shown in the attached crops, have what looks like ink spray. Is this do to the paper thickness set too high? The rest of the pint is clean.
