When it is shifted, the The staple shift motor (M3) is used for shift.
Page 113 SF-S55N 2) Operation 3) Stop position detection The stapler unit is shifted only when single stapling or The stapler unit stop position is detected by the double stapling is performed. It is not shifted when stapler unit position sensor (S2). This sensor consists corner stapling is performed.
