Manual

Use the Kofax Virtual ReScan Software which shipped with your scanner to process the scanned
data. Such 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 strip to the left of the scanner glass.
Check the JPEG 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 it face-up 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
www.hp.com,
select 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.
●
To optimize data transfer from the scanner to the scanning software on the computer, enable
scanner hardware (JPEG) compression. Typically, the use of scanner compression reduces the
time to complete all color scans and grayscale scans with resolution above 300 dpi. Scanner
compression affects the rate of data transfer only and can be used with all output formats.
NOTE: You cannot use scanner compression with black and white originals.
●
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). Turn on OCR only when you need a searchable document.
NOTE: For the best OCR results, scanner compression should be set to the minimum
compression level or disabled.
●
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.
The scan is completely black or completely white
The item might not be placed correctly in the document feeder. Make sure that the item you are trying
to scan is placed face up.
