The quality of the scan is not as expected. Calibrate the scanner to improve scan quality.

Turn on the printer.
Load a single sheet of plain white paper into the scanner with the edge of the paper straight and flush against the paper guide on the right side of the scanner.

When the paper is loaded into the scanner, the printer pulls it partially into the scanner, and the scan light brightens. If the scanner does not pull in and hold the paper, remove the paper, and then load it into the scanner again.
Search Windows for HP, and then click your printer name from the list of results.

HP Printer Assistant opens.
Click Print, and then click Maintain Your Printer.

The printer toolbox opens.
On the Scan Services tab, click Calibrate Scanner . If the printer does not pull in the paper, wait until the Calibration Unsuccessful message displays, click Close, and then repeat these steps.

The scanner pulls in the sheet of paper, and the scanner calibrates. Do not remove the sheet of paper until it has passed completely through the scanner.
When the calibration completes, click OK.
