Scanning Problems 315
❏ In Home Mode, select Black&White as the Image Type setting. In Professional Mode,
select None for the B&W Option setting. Then try adjusting the Threshold setting.
❏ Check your OCR software manual to see if there are any settings you can adjust in your
OCR software.
Scanned Colors Differ From the Original Colors
❏ Change the Image Type setting in Epson Scan’s Home or Professional Mode. See
"Selecting Basic Settings" on page 142 for instructions. Select different combinations of
this setting and the others mentioned below.
❏ Change the Display Gamma setting to match your output device, such as a monitor or
printer, in the Epson Scan Configuration window. See Epson Scan Help for details.
❏ Adjust the Auto Exposure setting in Epson Scan’s Professional Mode. Also try
selecting a different Tone Correction setting. See "Adjusting the Color and Other Image
Settings" on page 153 for instructions.
❏ Try selecting the following settings in the Configuration window: Color Control,
Continuous auto exposure, and Recommended Value (on the Color tab). See
Epson Scan Help for details.
❏ Check the color matching and color management capabilities of your computer, display
adapter, and software. Some computers can change the palette of colors on your
screen. See your software and hardware manuals for details.
❏ Use the color management system for your computer: ICM for Windows or ColorSync
for Macintosh. With Windows, add a color profile that matches your monitor to improve
on-screen color matching. (Exact color matching is very difficult. Check your software
and monitor documentation for information on color matching and calibration.)
❏ Printed colors can never exactly match the colors on your monitor because printers and
monitors use different color systems: monitors use RGB (red, green, and blue) and
printers typically use CMYK (cyan, magenta, yellow, and black).
You Have Trouble Adjusting the Scan Area in the Thumbnail Preview
❏ Create a marquee or adjust the existing marquee to select the area you want to scan.
See "Adjusting the Scan Area (Marquee)" on page 151 for instructions.
❏ In the Configuration window, adjust the thumbnail cropping area using the Thumbnail
Cropping Area slide. See Epson Scan Help for details.
