The present proposal addresses a method for folding signature booklets in an electrophotographic system. It significantly improves the folding process by reducing or even eliminating set skew and sheet scuffing. As illustrated by the figure, a document set 20 is registered in a flat state on a complier deck 30. The document set 20 may be comprised of either a loose stack of copy sheets, a stitched set of copy sheets, or a single copy sheet. Complier deck 30 is located beneath a first pair of fold rolls 22 and a second pair of fold rolls 24. At the start of the folding process, both the first pair of fold rolls 22 and the second pair of fold rolls 24 are at rest. They are retracted up and away from the document set 20 (shown by a plurality dotted circles).
