Some error conditions disable scanning and cause the document
transport to stop. This is done to prevent additional images from
entering the image buffer while allowing the host to perform fault
recovery activities.
NOTE: The scanner cannot determine exactly which images were
affected by the error and which images were not.
If an error occurs that disables the scanner, the host can continue to
read images from the image buffer without enabling the scanner.
However, when the image buffer has been emptied, an error will be
generated indicating fault recovery is required. This differentiates
between an end-of-job disable and a disable caused by an error. The
operator may continue scanning documents after the host enables the
scanner.
This section provides job stream examples which can be used in
scanning applications.
The host application is responsible for determining the order in which
the scanner returns images. Front images must always be retrieved
before rear images.
This job stream is available for all i600 Series Scanners.
1. Prepare documents.
2. Start the scanner to do black and white duplex scanning (front black
