11-1. Exposure Lamp LA1
An AC halogen lamp is used as Exposure Lamp LA1.
As the exposure level is adjusted on the control panel, the duty ratio of the pulse of AVR
Remote from PWB-A changes to increase or decrease the LA1 voltage, thereby chang-
ing the image density.
In Photo mode, the voltages are varied on a level 3V (200V Areas: 6V) lower than the
manual Exposure Lamp voltages.
