Hint The Relationship Between Data Volume and Scanning Resolution The higher the magnification and scanning resolution settings, the greater the file size of scanned images. There are certain inconveniences associated with large data volumes, such as longer processing times and the risk of running out of memory resources. You are advised against setting the resolution higher than necessary. For example, if you scan an A4 (21.0 x 29.7 cm (8.3 x 11.7 in.)) size image in the color mode, the amount of data varies according to the resolution. 408MB A4 color image 102MB 25.5MB 1.6MB 6.3MB 75dpi 150dpi 300dpi 600dpi 1200dpi * These numbers are approximate and may differ from actual scan results. 20

The Relationship Between Data Volume and Scanning Resolution
The higher the magnification and scanning resolution settings, the greater
the file size of scanned images. There are certain inconveniences associated
with large data volumes, such as longer processing times and the risk of
running out of memory resources. You are advised against setting the
resolution higher than necessary. For example, if you scan an A4 (21.0 x 29.7
cm (8.3 x 11.7 in.)) size image in the color mode, the amount of data varies
according to the resolution.

Drag the slider bar in either
direction or use the arrow
keys to change the resolution.
