Solution 2: Make sure that the glass and the back of the document lid are clean
Solution: Turn off the product, unplug the power cord, and use a soft cloth to wipe
the glass and the back of the document lid.
For more information, see:
• Clean the lid backing
• Clean the glass
Cause: The glass and the back of the document lid were not clean.
If this did not solve the issue, try the next solution.
Solution 3: Make sure that the scan document settings are set to the correct optical
character recognition (OCR) language
Solution: Select the correct OCR language in the software.
NOTE: If you are using the HP Photosmart Software, the Optical Character
Recognition (OCR) software might not be installed on your computer. To install
the OCR software, you must re-insert the software disk and select OCR under the
Custom installation options.
See the documentation that came with Readiris, or whichever OCR software you use,
for information on how to select the OCR language.
Cause: The scan document settings were not set to the correct optical character
recognition (OCR) language.
The OCR language tells the software how to interpret the characters it sees in the
original image. If the OCR language does not match the language in the original, the
scanned text might be incomprehensible.
