Scanner resolution and color
If you are printing a scanned image, and the quality is not what you expected, you might have selected
a resolution or color setting in the scanner software that does not match your needs. Resolution and
color affect the following qualities of scanned images:
● Clarity
● Texture of gradations (smooth or rough)
● Scan time
● File size
Scanning resolution is measured in pixels per inch (ppi).
NOTE: Scanning ppi levels are not interchangeable with printing dpi (dots per inch) levels.
Color, grayscale, and black and white define the number of colors possible. You can adjust the
scanner hardware resolution to up to 600 ppi.
The resolution and color guidelines table lists simple tips that you can follow to meet your scanning
needs.
NOTE: Setting the resolution and color to a higher values can create large files on disk and slow the
scanning process. Before setting the resolution and color, determine how you are going to use the
scanned image.
