Take steps to improve the scan quality<br />
◦ Use high-quality originals.<br />
◦ Place the media correctly. If the media is placed incorrectly on the scanner glass, it<br />
might skew, which causes unclear images. For more information, see Load an original<br />
on the scanner glass.<br />
◦ Adjust the software settings according to how you plan to use the scanned page.<br />
◦ Use or make a carrier sheet to protect your originals.<br />
◦ Clean the scanner glass. See Clean the scanner glass for more information.<br />
Scan defects are apparent<br />
• Blank pages<br />
Make sure that the original document is placed correctly. Place the original document<br />
face down on the flatbed scanner with the top-left corner of the document located in<br />
the lower-right corner of the scanner glass.<br />
• Too light or dark<br />
◦ Try adjusting the settings. Be sure to use the correct resolution and color settings.<br />
◦ The original image might be very light or dark or might be printed on colored paper.<br />
• Unwanted lines<br />
Ink, glue, correction fluid, or an unwanted substance might be on the scanner glass.<br />
Try cleaning the scanner glass. See Maintain the device for more information.<br />
• Black dots or streaks<br />
◦ Ink, glue, correction fluid, or an unwanted substance might be on the scanner<br />
glass, the scanner glass might be dirty or scratched, or the lid backing might be<br />
dirty. Try cleaning the scanner glass and lid backing. See Maintain the device for<br />
more information. If cleaning does not correct the problem, the scanner glass or<br />
lid backing might need to be replaced.<br />
◦ The defects might be on the original and not a result of the scanning process.<br />
• Unclear text<br />
Try adjusting the settings. Make sure that the resolution and color settings are correct.<br />
• Size is reduced<br />
The <strong>HP</strong> software settings might be set to reduce the scanned image. See the product<br />
software Help for more information about changing the settings.<br />
