• Make sure you do not move the document or the Epson Stylus CX7300 Series while scanning.
• Make sure the Epson Stylus CX7300 Series is placed on a flat, stable surface.
• Select Unsharp Mask in Epson Scan’s Professional
Mode.
• Adjust the Auto Exposure setting in Epson Scan’s Professional Mode.
• Increase the Resolution setting in Epson Scan’s Home or Professional Mode.
Image Colors are Patchy at the Edges
If your document is very thick or warped at the edges, cover the edges with paper to block
external light as you scan.
Image Is Too Dark
• Adjust the Auto Exposure setting in Epson Scan’s Professional Mode.
• Check the Brightness setting in Epson Scan’s Home or Professional Mode, or adjust
brightness using the Histogram in Professional Mode (see Epson Scan Help).
• Check the brightness and contrast settings of your computer monitor.
Back of Original Image Appears in Scanned Image
If your original is printed on thin paper, images on the back may be visible to the Epson Stylus
CX7300 Series and appear in your scanned image. Try scanning the original with a piece of black
paper placed on the back of it.
Ripple Patterns Appear in Image
A rippled pattern (called a moiré) may appear in a scanned image of a printed document. It is
caused by interference from the differing pitches in the scanner’s screen and the halftone screen in
your original. To reduce this effect:
• Select the Descreening option in Epson Scan’s Home or Professional Mode.
• Select a lower Resolution setting in Epson Scan’s Home or Professional Mode.
Image Colors Do Not Match Original Colors
• Change the Image Type setting in Epson Scan’s Home or Professional Mode. Select different
combinations of this setting and the others mentioned below.
• Try selecting a different Tone Correction or Auto Exposure setting in Professional Mode.
• 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.
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).
Scan Area Not Adjustable in Thumbnail Preview
• Create a marquee or adjust the existing marquee to select the area you want to scan in Home
or Professional
Mode.
