C/Z Fold Types
C-Fold
A C-Fold has two folds, which create a three-panel output.
Z-Fold
A Z-Fold has two folds that are folded in opposite directions, resulting in a type of fan fold.
Z-Fold Half Sheet (shown here with 3-hole punch)
As with a regular Z-Fold, the Z-Fold Half-Sheet has two folds that are folded in the opposite directions. The difference between a regular Z-Fold and a Z-Fold Half Sheet is that the Z-Fold Half Sheet is not folded in two equal folds. The two folds are unequal which allows one edge of the Z-Fold Half Sheet to have a longer edge. The longer edge allows for stapling or hole punching.
Note: Each Z-Fold Half Sheet added to a stapled set counts as 10 sheets. It reduces the total number of sheets for any given specified weight range.
