13. 2 Mechanical operation Flatbed operation When scanning place the document on the flatbed glass platen the flatbed optical unit carrier moves across the underside of the glass and scans the document A charge coupled device CCD mounts to the carrier and optically reads the image from the page The carrier is driven by a 2 phase stepping motor which moves the carriage at 1 600 inch each step Auto Document Feeder operation When using the Auto Document Feeder ADF mechanism a page is fed into the ADF by a pick roller and through the ADF by feed rollers A separation pick pad located opposite the pick rollers is used to properly feed the pages one at a time when placed on the input tray The flatbed optical unit carrier is positioned to the far left so when the paper passes through the ADF the bottom of the page is scanned by the flatbed CCD The home position sensor detects when the carrier is in the proper position for ADF scanning In addition an ADF cover open sensor detects when the upper ADF assembly is open or closed into proper operating position The scanner cannot operate when this sensor is open While the page is fed through and scanned from the bottom via the flatbed CCD the top of the page is simultaneously scanned via a CCD unit positioned within the ADF unit As the page feeds between the two CCD units the page discharges to the exit tray on the left side of the ADF Automatic document feeder ADF Paper input tray
