Bar code recognition The i600 Series Scanners do not include a bar code accessory. The
host system provides bar code functionality. The main imaging
parameter, which may effect 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.
Controlling print strings Full control and access to the scanner’s print string functionality is
available to the host application. In addition, the print string information
is returned to the host in the image header.
Print string formatting • Maximum character length 40.
• Character set full alphanumeric, including special characters.
• Distance from lead edge a minimum of a .035-inch.
• Can print to within ½-inch of the trial edge.
Electronic color
dropout
The i600 Series Scanners provides the ability to create dropout images
without changing lamps. Red, green, blue dropout functionality can be
selected. Only one color can be dropped out at a time. This dropout
performance is equivalent to color dropout functionality when using the
traditional color lamp technique.
Electronic color dropout is used with OCR and ICR applications. See
your vendor’s documentation for recommendations on image quality
characteristics.
Electronic color dropout is applied to the black and white image only.
There are four imaging parameters, which effect electronic color
dropout: Threshold Value/Filter Threshold, Background Value/
Background, Contrast %, and Threshold. The default settings are:
Contrast% = 0
Threshold = 90
Color Filter = 175
Background = 245 this value should be set to match background
color of your document.
If the values above do not give you the desired results, you may need to
vary these values accordingly.
