I have a C308 that puts a light line/border at the bottom of the page when doing booklets. (8 1/2 x 11R) at 64.7% reduction. Happens off the glass or the DH. Cleaned optics, not a problem on prints so it's optics related. Tried to reset background enlargement (default is .999%) up 15 bits but did not help. Any suggestions?
