Make sure there are no curls, wrinkles, staples, paper clips, or any other attached material. Order maintenance and scanning supplies You can purchase maintenance parts for your scanner. 1. Visit the HP scanner parts Web site at www.hp.com/buy/parts 2. Select your language, and then click the arrow. Clean the scanner glass Both strips of glass in the scanner should be cleaned periodically. The two small strips of gray reflective material should be lightly dusted if debris is present. To clean the strips of glass, follow these steps: 1. Press and hold the Power button for 3 seconds to turn off the scanner, and then disconnect the USB cable and power supply from the scanner. 2. Open the scanner hatch. 3. Clean the glass by using a soft, lint-free cloth that has been sprayed with a mild glass cleaner. CAUTION: Use only glass cleaner to clean the scanner glass. Avoid cleaners that contain abrasives, acetone, benzene, and carbon tetrachloride, all of which can damage the scanner glass. Avoid isopropyl alcohol because it can leave streaks on the glass. Do not spray the glass cleaner directly on the glass. If too much glass cleaner is applied, the cleaner could leak under the glass and damage the scanner. 12 HP Scanjet 3000 Scanner
