Setting General Preferences

Check Box for Automatically Closing ScanGear After Scanning

When the Text Enhanced checkbox is selected and the acquiring application requests a Black and White scan in “Windowless” mode, ScanGear CS-S uses the Text Enhanced setting.

Using Text Enhanced for Scans

Text Enhanced is designed for use with OCR (Optical Character Recognition) software. This setting increases the contrast in black and white scanning to assist in the accurate recognition of characters in OCR software. Resolution should be at least 300 dpi for OCR scans.

For applications that operate in “windowless” (UI-less) mode (including most OCR applications), ScanGear CS-S automatically uses the Text Enhanced setting when the check box is selected and the application requests a Black and White scan.

Selecting Text Enhanced

For applications that request a Black and White scan and use no ScanGear CS- S window, you can select Text Enhanced.
