Move the slider left or right to change the resolution for the scanned image. The available range
displayed in the slider area are within the minimum and maximum range supported by your
scanner. The resolution slider will always display the correct range for the current scanner.
Choosing resolution values
Typically, when making copies of black and white documents, 100–150 dpi will create an image of
similar quality to the original. When making copies of color documents or photographs, 150–200
dpi will create an image of similar quality to the original.
Higher resolution settings are generally used for creating an image that can be enlarged without
losing image quality, but take longer to scan and produce large files.
Some resolution settings for typically scanned items are:
• Text d o cument letters, forms, or other typed black and white documents – 100 dpi to 150 dpi
• Text d o cument letters or forms with hand printed text – 150 dpi
• Text d o cument (for OCR) forms, letters, memos, or spreadsheets – 300 dpi
• Business cards or other items with small print – 300 dpi
• Color page with graphics or color photographs – 150 dpi
• Color photographs of poor quality for image enhancement – 300 dpi
• Color photographs for printing – 200 dpi
• Color photographs for email – 100 to 150 dpi
• Magazine page with graphics, line art, or color photographs – 200 dpi
