We have available on the workstations a Scan icon. the process to be followed is fairly uniform. After placing the photo or document to be scanned face down on the scanner surface, squarely aligned, select the Preview option from the onscreen menu. This will produce a preview of the final scan. At this point, it is possible to change the scanning resolution, if so desired. As a rule, the higher the resolution (in DPIs, dots per inch), the higher the quality of the scan will be, with a corresponding increase in file size. Usually, the range will stay between 150 and 300dpi. Select Scan to complete the job and return to the Photoshop desktop.
