setting up 3880 for PiezoDN

I am setting up an Epson3880 for printing PiezoDN. I found a note in the instructions to print at least 11" wide, not letter size. Why? I also found a note about modifying the 3880 to avoid star wheel marks on film and a reference to a YouTube video. I could not find the video. Thanks for your help.

Hmm. No sure where you see that 11" wide comment.


But, here is the star-wheel procedure. You can print with letter size. Sometimes I add a 4" paper leader and a 4" paper trailer (taped letter paper) to the neg as well.
