176 Appendix G Scanner resolution and gray scale
EN
Overview
If you are printing a scanned image or copying an image and the
quality is not as you expected, you may have selected a resolution or
gray-scale setting in the Copier/Scanner software that does not match
your needs. Resolution and gray scale affect scanned and copied
images in the following ways:
●
Image clarity
●
Texture of gradations (smooth or rough)
●
Scan and copy time
●
File size
Resolution is measured in dots per inch (dpi) while gray scale is
measured by the number of grays possible to create a transition from
black to white. You can adjust the scanner resolution up to 300 dpi.
Gray scale can be set at 1 (black and white) or 8 (256 levels of gray).
Listed in the table, “Resolution and gray-scale guidelines,” are simple
tips you can follow to meet your scanning and copying needs. Also
see “
” and “
” to learn more about these topics.
Note
Setting the resolution and gray scale high can create large files that
take up disk space and slow the scanning or copying process. It is
important to determine how the scanned image is going to be used.
