Mechanisms 1 Operation The punching operation can be divided into the movement of the punch unit and the punch movement that makes holes. In the punch mode, these movements are performed for every sheet of paper, while in the non-punch mode these are not performed. However, the movement of the punch unit is performed for some paper sizes even in the non-punch mode. Punch control a Searching the standby home position of the punch unit Punch kit unit explanation With power turned on, M802 (punch shift) runs to move the punch unit to the position where PS803 (punch shift HP) is turned on, which makes a standby state. This position becomes the standby home position of the punch unit.
b Moving the standby position of the punch unit When the punch mode is selected, M802 (punch shift) runs to move the punch unit so that the paper edge sensor mounted on the punch unit is located inside of the side edge of paper by 5 mm. However, if the paper size is Letter, Legal, or 5.5 by 8.5R, the sensor is positioned by 10 mm inside. Either of these positions becomes the standby position in the punch mode. The above operation is not generally performed in the non-punch mode, however, for the paper sizes shown below, the punch unit is moved to the position located inside of the side edge of paper by 10 mm in order to secure the easy feeding of paper when conveyed.
The movement of the punch unit is driven by M802 (punch shift) and the punching operation is driven by M801 (punch). M801 is DC motor, and rotates once per punch. Related signals are PS801 (punch HP), PS803 (punch shift HP), and paper edge sensor. 2 holes / 4 holes / Inch 2 holes / Swedish 4 holes MFPs: B6 / 16K 3 holes MFP:
