Kodak i800 Series manual Disable scanning, Error handling

Disable scanning	Scanning is disabled to allow the host to download configuration/
	setup changes between jobs and to handle certain types of errors.
	Scanning is also disabled when one of the following conditions
	occur:
	• The scanner is first powered on using the power switch.
	• A SCSI bus device Reset command is executed.
	• An End-of-Job indicator is sent by the operator from the operator
	control panel.
	• A scanner-unique End-of-Job command is issued by the host
	computer.
	• An error occurs requiring fault recovery.
	NOTE: When scanning is disabled, documents cannot be scanned
	until the host enables scanning.
Error handling	The scanner recognizes and reports a variety of error conditions.
	Some errors are reported to either the host (via the SCSI interface) or
	the operator control panel, while others are reported to both the host
	and the operator control panel.
	An error (via the SCSI interface) is defined as either a current or
	deferred error.
	A current error results from a problem in processing the current
	SCSI 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 that may have occurred
	are reported after current errors.
	NOTE: Low level SCSI commands and information will be handled
	by your device driver. The following information is provided
	for reference only.
