Hi @Igor_Ivanov,


I'd like to help!


Try the below suggestions to resolve the issue -


Clean the scanner glass and parts

Fingerprints, smudges, dust, or debris on the scanner glass, under the scanner lid, or in the document feed slot can cause lines and color bands. Clean these parts with a soft, lint-free cloth sprayed with glass cleaner.

Examples of scanner types



1.Printer with flatbed scanner glass and lid

2.Printer with a document scan feeder

Reset the printer

Reset the printer to recover from printer errors or failures.

  1. If your printer has a rechargeable battery, remove it.

  2. With the printer turned on, disconnect the power cord from the printer.

  3. Unplug the power cord from the power source.

  4. Wait 60 seconds.

  5. Reconnect the power cord to a wall outlet and to the printer.


    HP recommends plugging the printer directly into a wall outlet.

  6. Turn on the printer to complete the reset.

Clean the automatic document feeder (ADF)

If your printer has an ADF, clean it regularly to help avoid paper jams and quality problems.

  1. Get a lint-free cloth and distilled water.

  2. Remove the original document from the ADF.

  3. Turn off the printer, and then disconnect the power cord.

  4. Open the ADF cover.

  5. Find the paper pick rollers and the separator pad inside the ADF.

    1.Paper pick roller

    2.Separator pad

  6. Lightly dampen a clean, lint-free cloth with filtered or distilled water, and then squeeze any excess liquid from the cloth.

  7. Use the damp cloth to clean the paper pick rollers and the separator pad.

  8. Leave the ADF cover open for two minutes to allow the rollers and pad to dry.

  9. Close the ADF cover.

  10. Reconnect the power cord, and then turn on the printer.

Change the scan settings

Change the settings in the scan software to help improve the scan quality of your document or photo.


Available settings vary by printer model, scan software, and when scanning a document or a photo. For example, the PDF settings are only available for document scans.

  1. Make sure the original document or photo is in good condition and free of tears, creases, folds, staples, or tape.

  2. Place the original on the scanner glass or into the automatic document feeder (ADF).


    Do not load photos into the ADF to prevent damaging them or the printer.

  3. Open the scan software, and then find the scanner settings.

  4. Change any of the following settings before scanning, if available.

    • Select the appropriate scan type: Make sure your scan type matches the object you are scanning for optimal quality.

    • Select either the color or greyscale scan option: If the original item is in color or greyscale, choosing to scan it in black and white can significantly degrade scan quality.

    • Increase the scan resolution: Increasing the resolution improves the scan quality, but it also increases scanning time and file size. A standard resolution of 300 dpi is acceptable for most text-based documents, while 600 dpi or higher is better for detailed photo scans.

    • Choose the appropriate file type: The file extension you choose can affect the final scan quality. For most scan jobs, PDF, JPEG, GIF, and PNG are acceptable file types.

    • Do not compress or reduce the file size: Compressing your scanned files produces smaller file sizes at a cost of lower image quality

  5. Scan the document or photo.

  6. On the preview screen, make any final scan adjustments, and then save the scan.

Hope this helps! Keep me posted.
