 Many modern scanners and multi-functional printers (MFPs) support the eSCL protocol. The protocol is a vendor-neutral network protocol that allows driverless scanning via ethernet, wireless and USB-connected devices. eSCL-compatible scanners advertise themselves via mDNS so that we can find them easily. mDNS is a zero-configuration service. It is implemented by Apple Bonjour and the open-source Avahi software packages.
 > See [this blog post](https://www.dynamsoft.com/blog/announcement/dynamic-web-twain-escl-scanner/) for more information about eSCL.
 
-#### Scan from an eSCL Scanner to PC
-> The Dynamsoft Service must be installed on the client PC
+- To scan from an eSCL Scanner to PC, the Dynamsoft Service must be installed on the client PC
+- To scan from an eSCL Scanner to Android, you must install the Android Service on the client device from the [Play Store](https://play.google.com/store/apps/details?id=com.dynamsoft.mobilescan).
 
+The following code shows how one way to acquire the image via the eSCL protocol.
 ``` javascript
-//Get a list of eSCL scanners:
-let eSCLDevices = await DWObject.GetDevicesAsync(Dynamsoft.DWT.EnumDWT_DeviceType.ESCLSCANNER);
-
-//Scan documents from the first eSCL scanner:
-let deviceConfiguration = {Resolution:100,IfShowUI:false}; // scanning configuration. Check out the docs to learn more: https://www.dynamsoft.com/web-twain/docs/info/api/WebTwain_Acquire.html#acquireimage
-await eSCLDevices[0].acquireImage(deviceConfiguration, DWObject);
