Looks like ink from rollers on the back of the print -- epson 7880

I noticed that when printing today with my 7880, that i was getting faint marks on the back of my prints, fairly evenly spaced looking like ink-- maybe an inch apart. How should i clean the “rollers.” thanks in advance.

I think I discovered the issue! I had been running double-sided paper with printing on both sides for some books I was making. I guess, I didn’t let the prints dry sufficiently! All better today.

Use simple green and a lint free cloth

Warm regards
