12-1. 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 changing the image density.
In Photo mode, the voltages are varied on a level 5V lower than the manual
Exposure Lamp voltages.

*If reduction copies are made using large size paper, the trailing edge of the first
copy moves past PC51 after the SCEND signal for the second copy has been
generated. If LA1 is turned ON for the second copy at the same timing as the first
one, therefore, the image for the second copy is produced on the trailing edge of
the first copy. To prevent this from occurring, LA1 is turned ON for the second and
subsequent copies when all of the following conditions are met:
D Approx. 0.8 sec. or more have elapsed after the first copy deactivated PC51.
D The PC51 output is HIGH.
D The SCEND signal for the second copy is output.
