Enable scanning

Enable scanning

The host must issue a Scan command to enable scanning before

 

documents can be transported through the scanner. If scanning has not

 

been enabled, the feeder and transport system will not turn on.

Initiate polling

Initiate host system polling of the scanner to ensure scanned document

 

images are transferred from the image buffer to the host system.

 

Polling should continue until scanning is disabled.

 

For more information see the sections entitled, “Controlling image

 

transfer order” and “Image header information” later in this chapter.

Feed documents

Feed documents according to the instructions found in the Kodak i600

 

Series Scanners User’s Guide.

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 1394 bus device Reset command is executed.

 

A scanner unique End-of-Job command is issued by the host

 

 

computer.

 

Transport timeout is set to End-of-Job.

 

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 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.
