# ScanSource Object (IScanSource Interface)
This object is implemented in FRE for Windows.
This object exposes a set of properties and methods concerned with scanning source.
## Properties
| Name | Type | Description |
| --------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Application | [Engine](/fine-reader/engine/api-reference/engine-object-iengine-interface), [read-only](/fine-reader/engine/guided-tour/advanced-techniques/programming-aspects/working-with-properties#readonly_properties) | Returns the Engine object. |
| ApiType | [ScanSourceApiTypeEnum](/fine-reader/engine/api-reference/enumerations/scansourceapitypeenum), read-only | Returns the API type used by the scanning source (TWAIN or WIA). |
| AvailableUserInterfaceTypes | [int](/fine-reader/engine/guided-tour/advanced-techniques/programming-aspects/working-with-properties), read-only | Describes the possible types of user interface for setting scanning options as a bitwise OR of [ScanSourceUITypeEnum](/fine-reader/engine/api-reference/enumerations/scansourceuitypeenum) constants. |
| Capabilities | [ScanSourceCapabilities](/fine-reader/engine/api-reference/mechanism-objects/scansourcecapabilities), [read-only](/fine-reader/engine/guided-tour/advanced-techniques/programming-aspects/working-with-properties#readonly_properties) | Returns the settings that are supported by the scanning source. |
| Name | [BSTR](/fine-reader/engine/guided-tour/advanced-techniques/programming-aspects/working-with-properties), read-only | Returns the name of the scanning source. |
| ScanSettings | [ScanSourceSettings](/fine-reader/engine/api-reference/mechanism-objects/scansourcesettings), [read-only](/fine-reader/engine/guided-tour/advanced-techniques/programming-aspects/working-with-properties#readonly_properties) | Returns the current settings of the scanning source. |
| Status | [ScanSourceStatusEnum](/fine-reader/engine/api-reference/enumerations/scansourcestatusenum), read-only | Returns the current status of the scanning source. |
## Methods
| Name | Description |
| ---------------------------------------------------------------------------------------------------- | -------------------------------------------------------- |
| [BeginScan](/fine-reader/engine/api-reference/mechanism-objects/scansource/beginscan-method) | Starts an asynchronous scanning operation. |
| [CancelScan](/fine-reader/engine/api-reference/mechanism-objects/scansource/cancelscan-method) | Allows you to cancel an asynchronous scanning operation. |
| [ResetSettings](/fine-reader/engine/api-reference/mechanism-objects/scansource/resetsettings-method) | Resets scanning source settings to default values. |
| [Scan](/fine-reader/engine/api-reference/mechanism-objects/scansource/scan-method) | Performs scanning of one or several images. |
