Remarks
The WSD Scan Service must support the CreateScanJobRequest operation.
The CreateScanJobRequest operation is the main mechanism to prepare a scan device to scan the images that are available to it. This operation can be initiated in two different methods. Each method will send different arguments to CreateScanJobRequest. The two methods and arguments are:
The user selects a destination and pushes the scan button at the device. In this method, the client sends a CreateScanJobRequest with the following child elements:
The ScanIdentifier element that the Scan Service returns to the client through ScanAvailableEvent. The Scan Service should check this identifier to ensure that the correct client is requesting the scan after the user has selected the destination.
The DestinationToken element that the WSD Scan Service returns to the client when it subscribed to receive ScanAvailableEvent events. The Scan Service should check that the correct client is requesting the scan by checking this token.
A ScanTicket element to control the processing of the scan. The values in the scan ticket are the default values that are set at the client before the user went to the device to initiate the scan.
The user starts an application on the client and acquires an image. In this method, the client sends CreateScanJobRequest with only the ScanTicket element.
Certain elements within the CreateScanJobRequest hierarchy can contain the MustHonor Boolean attribute. If MustHonor is present and true, the WSD Scan Service must honor the requested element and its value or reject the scan job request. If an unsupported element does not have a MustHonor attribute, or if its MustHonor attribute is false, the WSD Scan Service must ignore it. If a supported element's MustHonor attribute is false, the WSD Scan Service must substitute the requested value with a supported one.
If the client supplies a conflicting combination of elements in the scan job request (such as InputSource and Resolution), the WSD Scan Service must reject the scan job request if the conflicting elements have a MustHonor attribute value of true.
The following elements can have the MustHonor attribute: ColorProcessing, CompressionQualityFactor, ContentType, Exposure, FilmScanMode, ImagesToTransfer, InputSize, InputSource, MediaSides, Resolution, Rotation, Scaling, ScanRegionHeight, ScanRegionWidth, ScanRegionXOffset, and ScanRegionYOffset.
This operation can return all of the common WSD Scan Service operation error codes. For more information about how to report errors, see WSD Scan Service Operation Error Reporting.
CreateScanJobRequest can also return the following errors:
ServerErrorNotAcceptingJobs The server cannot accept a new scan job. This error might occur because the scanner has been put into service mode or because there is a user intervention condition and all the memory buffers have been exhausted. The client can try the unmodified request again at some later point in time with an expectation that the server has become unblocked and the scanner is accepting jobs again.
Fault property Definition [Code] soap:Receiver [Subcode] wscn:ServerErrorNotAcceptingJobs [Reason] The service is temporarily blocked and cannot accept new job or document requests. [Detail] None ClientErrorFormatNotSupported The scanner does not support the supplied Format value.
Fault property Definition [Code] soap:Sender [Subcode] wscn:ClientErrorFormatNotSupported [Reason] The Document Format parameter value is not supported. [Detail] Optional. The Scan Service can return a list of supported formats. The data in this element should be of type <wscn:FormatSupportedType>. ClientErrorInvalidScanIdentifier The supplied ScanIdentifier value is not currently valid within the scan device.
Fault property Definition [Code] soap:Sender [Subcode] wscn:ClientErrorInvalidScanIdentifier [Reason] The ScanIdentifier parameter value is not currently valid. [Detail] None ClientErrorInvalidDestinationToken The supplied DestinationToken value is not valid for the scan device.
Fault property Definition [Code] soap:Sender [Subcode] wscn:ClientErrorInvalidDestinationToken [Reason] The DestinationToken parameter value is not currently valid. [Detail] None ClientErrorNoImagesAvailable The server can't accept a new scan job because there is no media to be scanned. For example, this error is generated when a scan job is executed from the Automatic Document Feeder attached to the scanner, and the feeder is empty. The client can try the unmodified request again later, with the expectation that the condition was fixed and the scanner now has media to be scanned.
Fault property Definition [Code] soap:Sender [Subcode] wscn:ClientErrorNoImagesAvailable [Reason] The server has no images available to acquire. [Detail] None
Examples
The following code example shows a scan job request when the scan is initiated from the scanning device.
