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.
