Using the HP Deskjet F4480 printer/scanner, is it possible to set a scanned image to save as an image file?

Every time I scan an image using the HP Deskjet F4480 printer/scanner, it automatically saves as a .pdf file. Is there a way to set the scanner to save scanned images as image files? (.jpeg, .png, etc.)

Dell Dimension E310 Desktop
Windows XP Home Edition Service Pack 3
