HP CM1015 manual Resolution and color guidelines, Setting Recommended use

Scanning resolution is measured in pixels per inch (ppi). Color, grayscale, and black and white define the number of colors possible. Adjust the scanner hardware resolution to up to 1200 ppi. The software can perform an enhanced resolution up to 19,200 ppi. Also, set color and grayscale at 1 bit (black and white), or at 8 bit (256 levels of gray) to 24 bit (true color).

The resolution and color guidelines table lists simple scanning tips.

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 the scanned image is being used.
