HP LaserJet Enterprise MFP - Resolve Scan Image Quality and Performance Issues

note:

You can adjust scan settings from the printer control panel. The options and steps vary according to the type of control panel. Some of the scan settings that you can change from the control panel are default settings. Other settings affect the current job only. HP recommends using the Embedded Web Server (EWS) to configure the default settings on network-connected printers with FutureSmart 3 or FutureSmart 4 control panels.

• Images with a high resolution produce a better image quality, but will have a large file size.
• Images with a low resolution produce a poor image quality when the original file size is decreased.

• Resolution is set to a low value
• Scan color is set to Black
• High Compression is enabled

• Resolution is set to a high value
• Scan color is set to Color or Black/Gray
• High Compression is enabled

• Troubleshoot long scan processing time or slow output
• Troubleshoot poor image quality
• Troubleshoot images with large output file size

1. From the Home screen on the printer control panel, scroll to and select the Administration menu, and then select Scan/Digital Send Settings.
2. Select a scan category and then select the Default Job Options to configure the settings.
3. Select the Color/Black setting.
4. Select either the Color or the Black/Gray option, and then select the Save button.

   note:

   Selecting the Black option uses 1-Bit images which require a long scan processing time.

   If the Color setting is set to Black, make sure to select the Photograph option in the Optimize Text/Picture setting.

5. Select the Resolution setting.
6. Select a low resolution value to retain an acceptable image quality, and then select the Save button.

   note:

   An image with a high resolution creates a large file size and increases the scan processing time.

7. Select a Document File Type setting, and then select the File Options button.

   note:

   Make sure not to select an OCR file type because this file type requires a significant processing time.

   Do Not enable advanced features such as Erase Edges, Cropping Options, Blank Page Suppression, or Auto Orientation.

8. Select to clear the High Compression option, and then select the OK button.

   note:

   If the High Compression option is enabled for HP printer models released prior to Spring 2012, the scan processing time will take a long time.

10. Select either the 200 dpi or 300 dpi values to increase the scan image quality, and then select the Save button.

    note:

    Because reducing the image resolution decreases the file size and quality, it should generally be used as a last resort.

    Most clients have a specific resolution set to match their workflow, and reducing the resolution will most likely have a large impact on the entire workflow.

1. From the Home screen on the printer control panel, select Scan, select a scan category, and then select Options.
2. Make sure that the following options are not enabled: Erase Edges, Cropping Options, Blank Page Suppression.
3. Select the Color/Black setting, and then select one of the following options:.

   • Black/Gray (grayscale): For originals that contain black, white, and shades of gray
   • Black: For high quality originals that contain only black and white, such as line art, black text on white, or white text on black. Black scanning increases the scan time and compresses the file to smaller size.
4. Select the File Type and Resolution setting, and then select the type of file. JPEG is the best file type for scanning images to a small file size.

   note:

   Make sure not to select an OCR file type because this file type is for text recognition and requires significant processing time.

5. Configure the following settings, if available for the selected file type:
   • Quality and File Size: Select the Medium or Low option.
   • Resolution: Select a lower resolution. For best results, do not go below 300 dpi.
   • High Compression (smaller file): Select this check box if your are scanning to a PDF or XPS file type.
