145. F uses a step motor  and a series of sensors to  determine the media s position in the paper path during the scan process     The following steps are performed in creating a duplex scan on the X925 duplex ADF     1  To transfer text or an image from physical media to another piece of physical media or a digital file  the  following steps occur  The first step of the process is the placement of the paper on the scanner  The paper is  placed on the flatbed or the ADF paper tray  Once the paper is placed in the device the scan or copy command  is initiated by the user  This command can be issued from a computer or on the scanner itself     2  When the scan command is initiated  the ICC board on the scanner first polls the paper present sensor in the  ADF to see if there is paper in the ADF unit  If the paper present sensor indicates the presence of paper  the size  sensors are polled to determine the length and width of the paper  There are two paper length sensors  They are  found on the ADF input tray  These sensors detect A4 vs  folio for non US users  and letter vs  legal for US  users  The ADF paper width sensor is composed of three photo interrupt sensors that are actuated by the paper  guides on the ADF tray  The position of the guides places the three actuators on the guides in position to leave  the sensor open or closed  The width sensors detect A4  B5  and A5 widths for non US users and statement   executive  and letter widths for US users     3  With the size of the
