Firstly, navigate to HP Download Center, select your operating system from the drop-down list and click Next. After that, download and install the latest drivers and software available and connect the printer to your computer. If the product is connected with your Mac, lift its lid, place the picture on the right front corner of glass, touch the Scan option form the Home screen, tap Computer from the Scan to menu and follow the on-screen instructions. If you still have issues, I suggest you check the official user guide. You can find the scanning information in the chapter 6.
