I have inconsistency with the way in which the C75 folds and staples booklets using the square-fold booklet maker. Under the Administrative Tools section of the C75 interface, you can assign values for 2, variable and 15 page booklets which set the fold and staple position. I am searching for documentation that explains how these values affect each other and the final output. Does the machine average values from the three settings, or assign them to specific page counts? Even when set, the behavour is commmonly unpredictable requiring resetting (best guess) and the need of having multiple otions. I have had multiple techs take a run at this problem and no one seems to know how this interface works.
