Didn't happen the first few times I copied. The gutter shadows are on the opposite side of the book's binder on the copy. Shadows cause blurring and unable to read text on one side of copy? Still using the original ink cartridges.
It doesn't seem to be a matter of how the book is positioned on the copier, it didn't happen for the first 4 copies I made with the book. There is advanced printer option to check for gutter shadows and black frames on copies but didn't seem to work
