See Load paper and print media on page 49 for instructions. ● Adjust the software settings according to how you plan to use the scanned page. See Scanner resolution and color on page 84 for more information. ● If your product frequently feeds more than one page at a time, the separation pad might need to be replaced. Contact HP.
