HP 6700 - H7 Scan defects are apparent

The scanned image shows blots, lines, vertical white stripes, or other defects

◦If the scanner glass is dirty, the image produced does not have optimum clarity. See Maintain the printer for cleaning instructions.

◦The defects might be on the original and are not a result of the scanning process.

Graphics look different from the original Scan at a higher resolution.

NOTE: Scanning at high resolution can take a long time, and it can take up a large amount of space on your computer.

Take steps to improve the scan quality

◦Use the glass to scan rather than the ADF.

◦Use high-quality originals.

◦Place the media correctly. If the media is placed incorrectly on the scanner glass, it might skew, which causes unclear images. For more information, see Load an original on the scanner glass.

◦Adjust the HP software settings according to how you plan to use the scanned page.

◦Use or make a carrier sheet to protect your originals.

◦Clean the scanner glass. For more information, see Clean the scanner glass.
