Setting Resolution - Canon i-SENSYS MF3010 User Manual

Setting Resolution

A scanned image is a group of dots which contain color and brightness information. The density of these dots is called the
"resolution". The "dpi (dots per inch)" means the maximum dots a printer can print per inch. Set the resolution by specifying
the following options.
MF Toolbox -> [Image Quality]
ScanGearMF -> the advanced mode tab -> [Output Resolution]
To display the scanned image on a monitor
Images are scanned at a resolution of 75 dpi, which is a typical monitor resolution.
To print from the printer
Scan the document at the printer's resolution.
IMPORTANT
To print the scanned image by scaling (enlarging/reducing)
If you print the scanned image by doubling its current size, for example, the actual resolution decreases by half. To
maintain sufficient print quality, you need to double the resolution, and vice versa.
Resolution and data size
If the resolution is doubled, the image size becomes four times larger. If the data size becomes too large, it may take
considerably longer to process the image, consequently causing an insufficient memory error as well as other unexpected
errors. To prevent this from happening, specify the minimum allowable resolution based on your purpose of the scan.
NOTE
When printing the scanned image from a color printer
As a color printer uses several different color inks to reproduce colors, the resolution can be decreased by half.
About the scanning resolution
The maximum resolution is as following.
Optical resolution: 600 dpi
Software interpolated resolution: 9600 dpi
