Technical Information Troubleshooting
Check the resolution of the original image. Hover the cursor over a page thumbnail for
a popup display. If the resolution is significantly above or below 300 dpi, recognition
is likely to suffer.
Make sure the correct document languages are selected in the OCR panel of the
Options dialog box. Only languages included in the document should be selected. In
particular, setting an Asian language for non-Asian texts (and vice versa) is likely to
produce unusable results.
Recognition results in Japanese, Korean and Chinese can be viewed and saved only if
your system has East Asian language support. See “Asian language recognition” on
Turn IntelliTrain on and make some proofing corrections. This is most likely to help
with stylized fonts or uniformly degraded documents. If IntelliTrain was running, try
turning it off – on some types of degraded documents it may not be able to help. See
“IntelliTrain” on page 50.
Do some manual training, or edit existing training to remove unsuccessful training.
If you use True Page as the Text Editor formatting level or for export, recognized text
is put into text boxes or frames. Some text may be hidden if a text box is too small. To
view the text, place the cursor in the text box and use the arrow keys on your keyboard
to scroll to the top, bottom, left, or right of the box.
Check the glass, mirrors, and lenses on your scanner for dust, smudges or scratches.
Clean if necessary.
Problems with fax recognition
Try these solutions to improve OCR accuracy on fax images:
Ask senders to use clean, original documents if possible.
Ask senders to select Fine or Best mode when they send you a fax. This produces a
resolution of 200 x 200 dpi.
Ask senders to transmit files directly to your computer via fax modem if you both
have one. You can save fax images as image files and then load them into OmniPage.
See “Input from image files” on page 25.
System or performance problems during OCR
Try these solutions if a crash occurs during OCR or if processing takes a very long time:
Check image quality. Consult your scanner documentation on ways to improve the
quality of scanned images.
