Kodak i100 Series manual Error handling

Error handling	The scanner recognizes and reports a variety of error conditions.
	Some errors are reported to the host (via the 1394 interface) or via the
	LEDs on the scanner while others are reported to both the host and
	the LEDs.
	An error (via the 1394 interface) is defined as either a current or
	deferred error.
	A current error results from a problem in processing the current
	scanner command. This can include sending an invalid
	command, trying to read from an empty image buffer, or an
	end-of-job condition. Since one or more errors may be pending at
	any time, current errors are reported first.
	A deferred error results from an error condition within the scanner,
	such as a document jam. Deferred errors are reported after
	current errors.
	NOTE: Low-level 1394 commands and information are handled by
	the device driver. The following information is provided for
	reference only.
	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.
