Hello Serene,
When you are operating the scanner from inside the EMR, you are locked into the options that AmazingCharts provides as it is activating the scanner via connection to the TWAIN, WIA or ISIS driver. AC's tech support should be able to tell you if this is the case. Should you be looking for an equally durable, perhaps more suitable for crowded front desks and less expensive scanners, take a look at http://www.ambir.com/Ambir-Workgroup-ADF-Scanners.
