I widened the edge space on the print to .25, but for the GO overlay left the fit box checked. That fixed it. The print goes to 1/4 in of the edges, but the GO overlay goes to 1/8 of the edges with a 1/8 in overlap of the print. Obviously the 3880 paper edge sensors are optical and not too smart. What can one expect for $1200.
Thanks Walter, for the response about sensor turn off, I might try that also
