HP Network Scanjet 5 Scanner series - Manual (Page 113)

A high percentage of incorrect characters appears in an item that
was converted with the OCR link.
The accuracy of the OCR link depends in large part on the quality, size,
and structure of the original document and on the quality of the scan
itself. To obtain the best possible results when using the OCR link,
choose a scan setting specific to text and do the following:
•
Process only pages that have crisp, clear text. Letters that have gaps, that
“bleed” along their edges, or that touch other letters will not work well
with the OCR link. Note that underlining and text that is close to
non-text items, such as graphics, will also degrade OCR results.
•
Process only pages that contain 9-point text or larger.
•
Adjust the Image setting to get the densest, clearest letters without any
“bleeding” along their edges.
•
Straighten pages either by rescanning the pages or by using the
Straighten Page command.
Import and Export File Problems
Exported files expand in size when opened in a paint program.
Many paint programs ignore the dpi resolution information in BMP,
PCX, and TIFF files. These programs assume that the resolution of the
file is the same as the current screen resolution. Because these files
actually contain more information than the screen can display, they grow
in size. The following are some possible solutions:
•
Instead of using the Export command, you can open the item in Page
View, cut out the information, and then paste it into the program you
want to use or into a new file in a paint program.
•
You can also open the file in a graphics program that accurately reads
the dpi resolution contained in the file.
Unable to import a file.
Check whether the file you want to import is saved in an appropriate
format, such as BMP, PCX, or TIFF. If it is none of these formats, select
the file type you want and try importing the file again.
You can also try opening the file in a paint program and saving it as a
BMP file under a new file name. Then try opening the new file in
PaperPort software.
