My hp psc will not scan an object everything else seems to work how do i fix it

Double Click on HP Solution Center icon to open. The HP icon will be on your desktop or in your start menu. It is the icon that materializes after you use the CD to install your HP scanner or multifunction printer. (It may appear slightly different depending on the model and type of HP scanner or printer).
Place the document or photo on the glass platen in the proper corner. There is an arrow that illustrates proper placement in HP scanners and printers.
Click the settings button on the bottom of the HP Solution center screen. It appears as a wrench. This will assist in setting up your scanner or all-in-one HP printer to scan at the touch of a button. Follow the on-screen prompts for photos and documents. Then, scan by clicking the Scan Picture or Scan Document button as appropriate.
Select the proper choice once you scan, such as save to file (specify where) or email (You also can set up a folder ahead of time so you know where to find the document or photos once they are scanned). Often times the computer will create a default my scans folder and organize them by saving them by date and month scan.
Click scan and then wait for box to appear. You will see the document or photo being saved and the blue bar will display progress in the HP screen.
Save the file if the HP software has not already done this for you. Put it in a folder you create and give it a name you will remember.
Then click "Save"to finalize it. The document should be in the folder that you designated.
Repeat the process for multiple pages. Keep the HP Solution Center screen open until your scans are finished.
