♦Caching
Specifies whether to preread (cache) when a document is scanned. This option enables faster scanning.
If processing of the application being used slows down and scanning stops, this option can be used to prevent degradation of the scanning speed. (The effect, however, depends on the environment being used.)
None
Caching is not performed.
