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 software can perform an enhanced resolution up to 19,200 ppi.
You can set color and grayscale at 1 bit (black and white), or at 8 bit (256 levels of gray or color) to 24 bit
(true color).
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 a large amount of
disk space and slow the scanning process. Before setting the resolution and color, determine how you are
going to use the scanned image.
