CHAPTER 2 OPERATION OVERVIEW
7.1.4 Horizontal registration operation
Side registration of the punch unit is driven by the punch registration motor (M17). The
side registration home position of the punch unit is detected by the punch home position
sensor (PI24). The punch unit shifts into position according to the edge of the paper that has
been detected by the punch paper edge sensor (PI21) and punch paper edge sensor home po-
sition sensor (PI23).
1) A paper size signal is sent from the copier. The punch paper edge sensor moves into po-
sition according to the size of the paper.
