Overview When you select the Saddle Stitch imposition method (Job parameters > Imposition method), and then select number of sets, the default gutter is set to 10 mm. This value is transparent to the user and cannot be changed. You are unable to print two sets of a smaller size paper on one larger sheet as the gutter size is too large. For example—you cannot print two sets of an A5 document on one A3 size paper.
