Capture the specified number of sheets of paper. A single sheet of paper may result in zero or more images, depending on various settings in the driver (i.e. CAP_DUPLEXENABLED, ICAP_AUTODISCARDBLANKPAGES, etc.)This is a read only capability.
An application must set CAP_XFERMECH to -1 before using this capability.
A CAP_SHEETCOUNT value of 0 requests that all of the available sheets are captured. A value of 1 or greater requests that only that number of sheets are captured.
Use DAT_EXTIMAGEINFO to determine which sheet and which side of a sheet an image came from
If CAP_XFERCOUNT is not equal to -1, then CAP_SHEETCOUNT is ignored.
If the value of CAP_SHEETCOUNT is equal to 0, then all of the available sheets are captured. For values greater than 0, the scanner captures the specified number of sheets. If the scanner runs out of sheets before the CAP_SHEETCOUNT value is reached, then the scanner automatically transitions to state 5.
