HP Printer Scan Quality Issue [Solutions]

To fix HP printer scan quality issues, do the following solutions in the given order. Once you have tried a solution, scan a document to confirm if the issue has been fixed.

If it is, then you shouldn’t continue with the next one. However, if it isn’t fixed, then move to the next solution and keep repeating this process until the scan quality issue is resolved.

1. Ensure that the Scan Quality Issue isn’t due to a Printing Issue

If your scan quality is poor, the first thing is to confirm that it has nothing to do with a printing issue. Therefore, to confirm, print a document by sending a job from your computer.

  • If you discover the quality issue on the print job, then the issue is not with scanning but printing. Therefore, you should go to the HP Customer Support website. After that, type in the model number of your printer, then type in “print quality” in the search box, and then find and click on the document for “Fixing Poor Print Quality”.
  • If you discover the quality issue isn’t on the print job, then it is most definitely a scanning problem which could be due to issues with your scanner hardware or the settings of the scan job.

Debris, smudges, dust, or fingerprints on the printer’s scanner glass, beneath the scanner cover, or in the automatic document feeder could lead to scan quality issues such as color bands and lines.

5. Change your Printer’s Scan Settings

To change your HP printer scan settings to fix scan quality issues, follow the steps below:

Note: The settings vary by the model of the HP printer, scan software, and what is being scanned (document or photo). For instance, PDF settings are not available for photo scans.

Step 1: Ensure that the condition of the original you want to scan is good. In other words, confirm that it has no tears, folds, staples, tapes, or creases.

Step 2: Put the original on your printer’s scanner glass. Alternatively, you can put it into your printer’s ADF (automatic document feeder) if that’s what your printer has.

Note: Don’t place photos into your printer’s ADF as they could get damaged in the process. Only scan documents with the automatic document feeder.

Step 3: Launch the software you want to use to scan.

Step 4: Find the scanner settings.

Step 5: Change these settings if they are available before you scan:

  • Choose the right scan type: Ensure that the scan type you choose is a match to what you want to scan to get the best quality.
  • Choose either grayscale or color: If your original is in grayscale or color, then scanning it using the black & white option can affect the scan quality negatively.
  • Increase scan resolution: Since you are dealing with scan quality issues, then you need to increase the resolution. A higher resolution will enhance the quality of the scan; however, the file size, as well as scanning time, will increase. Although 300 dpi is the standard resolution for documents that are text-based, you can increase it to 600 dpi or more when scanning detailed photos.
  • Select the right file type: Your scan quality can be affected by the file type (extension) you select. The usual file types are JPEG, PDF, PNG, and GIF.
  • Do not reduce or compress the file size: If you compress the scanned files, although you might have a smaller file, however, the quality will be affected.

Step 6: Scan the original.

The scan preview will then be displayed.

Step 7: Check the scan preview screen and make any adjustments you desire.

Step 8: Once you are done, save your scan.

6. Service your HP Printer

If none of the solutions above fixes the scan quality issue, then you need to contact HP Customer Support for further assistance. A repair schedule will then be fixed. Note that you will have to pay a repair fee if your product is out of warranty.
