Scanned image is fuzzy
●
Verify that the document original is not fuzzy.
●
Use the Kofax Virtual ReScan Software which shipped with your scanner to process the scanned
data. This software cleans up the image and compresses the data.
●
Check for any obstructions in the scanner paper path and make sure the paper width guides are
positioned appropriately. Try another scan.
●
Clean the scanning strips inside the document feeder.
●
Check the data transfer compression setting. If scanner compression is high, scanned data might
be lost by the compression.
Scanned pages are out of order at the scan destination
●
Verify that the page order of the original document is correct before placing the document face
down into the document feeder.
●
Make sure that there are no staples, paper clips, or any other attached material (such as adhesive
notes) that may cause the pages to feed incorrectly.
●
Verify that pages are not stuck together.
Optimize scanning and task speeds
Several settings influence the total time for a scanning job. When you want to optimize scanning
performance, consider the following information.
●
To optimize performance, make sure your computer meets the recommended system requirements.
To view minimum and recommended system requirements, see
lect your country/
region, search on your scanner model, and then search on datasheet.
●
In the scanning software, choose the layout setting that matches the orientation of the originals in
the document feeder.
●
In the HP Smart Document Scan Software, adjust the data transfer rate. A low setting produces a
higher quality scan image at a slower scan speed; a high setting produces a lower quality scan
image at a faster scan speed. For more information, see the HP Smart Document Scan Software
Help.
●
Saving a scanned image to a searchable format (for example, searchable PDF) takes more time
than saving to an image format because the scanned image is analyzed using Optical Character
Recognition (OCR). Verify that you need a searchable output file before selecting a searchable
scan format.
NOTE:
For the best OCR results, scanner compression should be set to the minimum
compression level.
●
Scanning at a higher resolution than necessary increases scanning time and creates a larger file
with no additional benefit. If you are scanning at a high resolution, set the resolution to a lower
level to increase scanning speed.
