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 input tray.
●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 input tray.
●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.
●For most fonts, 300 dpi is sufficient for using optical character recognition (OCR) to create editable text.
●For Asian fonts and small fonts, 400 dpi is the recommended resolution.
●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 input tray. Make sure that the item you are trying to scan is placed face down in the document input tray.
●If you are scanning to a black and white image, make sure your black and white threshold is not set to either extreme (0 or 255). Setting the threshold to an extreme will result in an image that is all white or all black.
Scanned images are not straight
●Verify that the document feeder guides are centered on the scanner and set to an appropriate width for the original being scanned. Make sure the paper guides touch the edges of the original.
