Pictured above is what I perceive to be the optimal placement of Bail rollers. The inside rollers from left to right should be at 3 and 5.25 respectively, with the margin set at 1, and the page set at 0. In Pica, this would be a margin at space 10, and the inner sides of the rollers at space 30 and space 52. When the rollers are too far apart, the page bows up in the middle and slaps around a bit.
