4.7.2 Job/Cache
Figure Option dialog (Job/Cache)
♦ Caching
Specifies whether to pre-read (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.
Read ahead
One document page is scanned, and the data is pre-read and stored in PC memory
(main memory of the personal computer).
Ram cache
Prereads the allowable amount based on the allocated memory size and stores the data
in PC memory.
A memory size between 1 and 200 MB can be set.
Use Memory on Scanner
Pre-reads using the memory installed in the scanner (displayed only if supported by the
scanner).
