To set a preference:
On the Preferences tab, click the desired preference check box. You can
select from the following options:
Text Enhanced
This option is designed for use with OCR (Optical Character
Recognition) software. This setting increases the contrast in black and
white scanning to promote the accurate recognition of characters in
OCR software. Resolution should be at least 300 dpi for OCR scans.
If selected, the text enhanced setting is used for applications that
request a black and white scan and do not use the scan window
(including most OCR applications).
n
Because the L6000 does not scan in color, the Canon ColorGear™ Color
Matching option has no effect upon your scan.
