14-1. Cooling of the Printer Interior
• The Cooling Fan Motors provided on the right and left frames of the printer draw outside
air from the outside into the printer interior and discharge heat inside the printer out. It
thereby prevents the temperature of the PH Unit and the printer interior from increasing.
