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.
IMPORTANT: Before beginning fault recovery, make sure all the
headers and images have been transferred from the
image buffer to the host system.
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
image address and sequential counter.
3. Use the information above +1 to seed the next image address and
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.
