Resolve issues with scanning documents or text (OCR)
The scanner uses optical character recognition (OCR) to convert text on a page to
text that you can edit on your computer.
English
● If you scan text but cannot edit it, make sure that you make the following
selections during scanning:
– HP Scanning (Select Document.)
– Scan to (Select a word-processing program or Save to File.)
Note If you select Save to File, select a text file type from the File
Type drop-down list.
● Scanned text might not appear on your computer exactly as it appeared on the
original, especially if the original contains faint or smudged text. For example,
some characters might be incorrect or missing. As you edit the text, compare the
scanned text against the original, and then make corrections as necessary.
●
Note The OCR software is installed automatically when you install the
HP Scanning software during scanner setup.
Scanned image is fuzzy
It is important that the item you scan comes in full contact with the scanner glass. If
the resulting scanned image is not clear, check to see that the item is in full contact
with the scanner glass.
Scanner is scanning items very slowly
● If you are scanning to edit text, the optical character recognition (OCR) software
program causes the scanner to scan more slowly, which is normal. Wait for the
item to scan.
● Some default settings can cause the scanner to scan more slowly. Open HP
Solution Center, click Settings, click Scan Settings and Preferences, and then
click Scan Preferences. On the Quality vs. Speed tab, clear the Scan at
maximum pixel depth check box.
● The resolution might be set too high. Reset the resolution to a lower level. The
scanner software automatically selects the resolution to provide the best balance
between image quality and file size.
To change the resolution, open HP Solution Center, and then click Settings.
Select Scan Settings, and then click Solution Center scan button settings.
Click the tab for Scan Document button or Scan Document To button, and
then click the Scan Document Settings button. The Scan Document Settings
dialog box is displayed. Use the drop-down list to change the resolution.
Scanner glass needs to be cleaned
Clean the scanner glass under the following conditions:
● Ink is on the glass.
● Fingerprints are on the glass.
● Items have excessive amount of dust or dirt on them.
● Smudges or other marks appear on scanned images.
