Processing Tray Unit

Outline

The processing tray unit aligns, shifts, and staples the delivered paper, and then delivers the paper stack onto the stack tray.
Note that alignment is not performed in the processing tray unit if shifting, stapling, or staple-free binding is not performed.
(However, alignment is performed for 2-sided print of A3 and B4 sheets weighing less than 64 g/m2.)
