When using this function with 1 Sided 
2 Sided and Mixed Sizes modes, always ensure that the originals of each size are in even numbers. If you have an odd number of originals, insert blank sheets to adjust the total.
Even if you have selected Face Up for Copy Eject Face Method in Glass Mode in User Tools, the copies will be delivered face down.
To use the Z-fold function, you must set the Z-fold support tray. For details about how to set the Z-fold support tray, see “When Folded Paper Is Not Properly Aligned”, Troubleshooting
.
Folded copies that are delivered to the folding unit tray may be stacked with their folds open. If this happens, the position of the folds is unaffected and the copies will still be output in sequential order. Stacked copies can be easily separated in the order they were delivered. To prevent their folded sections overlapping, configure the machine to deliver folded copies to the Finisher upper tray or Finisher shift tray.
Remove the Z-fold support tray when delivering copies to the Finisher shift tray or Multi-Folding Unit upper tray without using the Z-fold function. If you leave the Z-fold support tray in place, prints are not stacked properly.
