TWAIN Driver Settings (Mac)
The options and settings available vary depending on the machine.
1. Resolution
Select a scanning resolution from the Resolution pop-up menu. Higher resolutions produce a finer scanned
image but consume more memory and increase transfer time.
2. Scan Type
Select from a range of scan color depths.
• Black & White
Use for text or line art images.
• Gray (Error Diffusion)
Use for photographic images or graphics. (Error Diffusion is a method for creating simulated grayscale
images without using true gray dots. Black dots are put in a specific pattern to give a gray
appearance.)
• True Gray
Use for photographic images or graphics. This mode is more accurate because it uses up to 256
shades of gray.
• 24bit Color
Use to create an image with the most accurate color reproduction. This mode uses up to 16.8 million
colors to scan the image, but it requires the most memory and has the longest transfer time.
