Solve scanned-image problems

Problem

Solution
The scanned image is of poor quality.
The original might be a second-generation photo or picture.
  • To eliminate the patterns, try reducing the size of the image after scanning.

  • Print the scanned image to see if the quality is better.

  • Verify that the resolution settings are correct for the type of scan job that you are performing.

  • For best results, use the flatbed scanner for scanning rather than the automatic document feeder (ADF).

The image that appears on the screen might not be an accurate representation of the quality of the scan.
  • Try adjusting your computer monitor settings to use more colors (or levels of gray). Typically, you make this adjustment by opening Display in Windows Control Panel.

  • Try adjusting the resolution settings in the scanner software.

The original might have been loaded incorrectly.
Use the media guides when you load the originals into the ADF.
The scanner glass might be dirty.
Clean the scanner glass.
The graphics settings might not be suitable for the type of scan job that you are performing.
Try changing the graphics settings.
Part of the image did not scan.
The original might have been loaded incorrectly.
Load the original on the flatbed glass or use the media guides when you load the originals into the ADF.
A colored background might be causing images in the foreground to blend into the background.
Try adjusting the settings before you scan the original or enhancing the image after you scan the original.
The original is longer than 381 mm.
The maximum scannable length is 381 mm when you use the automatic document feeder (ADF) input tray. If the page exceeds the maximum length, the scanner stops. (Copies can be longer.)
CAUTION: Do not try to pull the original from the ADF; you might damage the scanner or your original. See Clear jams from the ADF.
The original is too small.
The minimum size that the flatbed scanner supports is 25 x 25 mm. The minimum size that the ADF supports is 127 x 127 mm. The original might be jammed.
The media size is incorrect.
In Scan settings, make sure that the input media size is large enough for the document that you are scanning. .
The scan takes too long
The resolution is set too high.
Change the resolution settings to the correct settings for your job.
The software is set to scan in color.
The system default is color, which takes longer to scan even when scanning a monochrome original. If you acquire an image through TWAIN or WIA, you can change the settings so that the original scans in grayscale or black-and-white. See the product software Help for details.
A print job or copy job was sent before you tried to scan.
If someone sent a print job or copy job before you tried to scan, the scan will start if the scanner is not busy. However, because the product and scanner share memory, the scan might be slower.
The scanning PC may not have enough available resources.
Close unused applications on the PC. If the scan is still too slow, try rebooting the scanning PC.
Antivirus, antispyware, or firewall software on the scanning PC may slow scanning.
Consult your antivirus, antispyware, or firewall software documentation.

Scan-quality problems

Prevent scan-quality problems

The following are a few simple steps you can take to improve copy and scan quality.

  • Use the flatbed scanner, rather than the automatic document feeder (ADF) input tray, to scan.

  • Use high-quality originals.

  • Load the media correctly. If the media is loaded incorrectly, it might skew, which causes unclear images.

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

  • If your product frequently feeds more than one page at a time, the separation pad might need to be replaced. Contact HP. See www.hp.com/support/CM2320series or the support flyer that came in the product box.
