Follow these steps to clean your printer:
1. Remove any paper loaded in the printer, and turn off the printer.
2. Use a soft brush to carefully brush away all dust and dirt from the outer case and sheet guide.
3. If the outer case and the sheet guide are still dirty or dusty, clean them with a soft, clean cloth
dampened with mild detergent dissolved in water. Keep the printer cover and front cover
closed to prevent water from getting inside the printer.
