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 features of scanned images:
●
Image 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 1200 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 high value can create large files that take up disk space
and slow the scanning process. Before setting the resolution and color, determine how you are going
to use the scanned image.
