There are many different areas that can affect the performance of
OmniPage Limited Edition and other programs. Check the following:
• If performance (or accuracy) is not acceptable, adjust the
brightness setting and try again. With some scanners, depending
on the quality of your original document, the wrong setting can
result in very slow recognition.
• Recognition performance varies with the quality, point size,
font, and density of the original document. A page of 8 point
type with 6,000 characters will take much longer to recognize
than a page of 12 point type with 2,000 characters. Also, pages
with complex formats require more recognition time than simple,
single-column pages.
• Make sure there is sufficient disk space for the temporary files
that Windows and OmniPage Limited Edition must create. For
best performance, your disk should have at least 25% of its space
free. If it has less space than this, files may be fragmented (that is,
written in small blocks in many different places on your disk).
This results in very slow performance.
• Optimize your disk regularly. When you start with a new hard
disk, all the data in one file is stored in contiguous blocks from
beginning to end. As you (and your programs) create, modify,
and delete files, DOS uses whatever space is available on your
disk. This means that small portions of files are stored in blocks
all over the disk; the disk becomes "fragmented." Instead of the
disk quickly reading the entire file in one operation, it must
search for all the individual blocks.
An optimization program reorganizes your disk and puts all
blocks of each file into a contiguous space. Programs that do this
are available from your computer dealer and should be run
regularly.
• Check for a computer virus. Computer viruses can corrupt your
system when you install software from infected disks or
download infected programs from modems. They can even get
into your system over a network connection. A virus can not only
slow down your system it can also damage your programs and
data. You should regularly check your system for viruses.
