An optical scanning apparatus includes a light source, a rotating polygonal mirror, a scanning optical system, a detector, and a light emission controller. Each leg section has an outer wall portion with apertures for impingement-cooling of nozzle wall portions in registration with the outer wall portions. The user may enter media information into the electronic system thereafter uploading the media information to the control station. The optical fiber exhibits an effective area of greater than about 60 \u03bcm2 at a wavelength of about 1550 nm, a dispersion slope of less than 0.
