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.
