Compaq P/N DOC-FB4B - Manual (Page 8)

1-4
Because scanners are capable of inputting large amounts of data in
relatively short periods of time, they commonly push computer
systems to the limits of their capabilities. Before beginning any
scanning task or operation, carefully consider your system’s
processing capabilities, especially processor speed, RAM, and
available hard disk space. OCR processes, fax operations, and the
processing of simple black & white graphics are least demanding.
High resolution scanning of large images in full color creates an
extreme demand for processor time and memory.
When you are scanning with the TWAIN interface, the number labeled
image size (calculated in bytes) provides the working file size that is
the result of the selected scanning mode, resolution, and image size.
Take careful note of this information.
