| Description: |
This capability is intended to boost the performance of a Source. The fundamental assumption behind AutoScan is that the device is able to capture the number of images indicated by the
value of CAP_XFERCOUNT without waiting for the Application to request the image transfers.
This is only possible if the device has internal buffers capable of caching the images it captures.
|
| Remarks: |
The application should check
PendingXFERs, and continue to scan until it becomes 0.
When AutoScan is set to TRUE, the Application should not rely on just the paper sensors (for example,
CAP_FEEDERLOADED) to determine if there are images to be transferred.
The latency between the Source and the Application makes it very likely that at the time the sensor reports FALSE, there may be more than one image waiting for the transfer inside of the device's buffers. Applications should use
PendingXFERs
to determine whether or not there are more images to be transferred.
