Jam and fault recovery
This section provides recommendations for application logic
associated with scanner jam and fault recovery.
If your scanner is enabled and you are polling when a document jam
or other fault occurs, use the following procedure to restart
scanning.
When a document jam or other fault occurs, the feeder and the
transport will stop and the scanner will be disabled.
1. When all images have been retrieved from the scanner
(image buffer empty), display the last image retrieved for
operator viewing.
2. Use the image header of the last image retrieved to
determine the sequential counter.
3. Use the information above +1 to seed the next sequential
counter before re-enabling the scanner.
4. Instruct the operator to sort through the stack of documents
being scanned to find the document that produced the last
successfully scanned image. They must rescan all of the
documents that follow the last successfully scanned
document.
5. Enable the scanner.
