Image file storage locations

This section provides general recommendations regarding the impact of image file storage locations on the overall throughput of the scanner.

You can receive up to four image files per document. Decisions about where to write these files when retrieving them from the scanner could impact the overall throughput of the scanner. In order to prevent overwriting data the scanner stops feeding paper when the internal image buffer reaches two-thirds capacity. Scanning will not resume until buffer memory reaches one-third. In order to minimize the number of times this condition might occur, it is recommended that image files are written to a local hard drive in order to avoid the potential overhead of transferring files across the network to remote drives during scanning.

Bar code recognition	This section provides general information about bar code recognition
	and read rates.
	The i1800 Series Scanners does not include a bar code accessory. The
	host system provides bar code functionality. The main imaging
	parameter, which may affect bar code read rates, is resolution. Either
	black and white, grayscale or color images may be used for bar code
	applications. Refer to your software documentation for their
	recommendations and/or requirements for image quality to achieve
	desired read rates.
Image addressing	Image address information only applies when the scanner is configured
	with Image Address enabled via the operator control panel
	touchscreen.
	The i1800 Series Scanners receive all image address functionality from
	the host. This includes index format, starting image address, image
	address format and level rules.
Image address format	The image address format can be from one to four fields. Each field
	may be up to 9 characters. Total image address length with delimiters is
	30 characters. Each field may use level 1, level 2, level 3, and fixed
	fields, and must be explicitly defined by the application. See Chapter 3
	or 4 (depending on your driver) for more information.
	The order of importance for the fields (from highest to lowest) is fixed,
	level 3, level 2, level 1. When defining an image address, the field with
	the highest importance must always be to the left. For example, F321 is
	a valid format. F123 is not a valid format.
	You are not required to use all four fields. If you chose to use fewer than
	four fields, you must specify a field width of 0 for any unused field. 0
	width fields may not be between two non-zero width fields.
	When defining fields, you can only have one field assigned to each
	individual level. For example, F21 is a valid format. F11 is not a valid
	format.
