31 December 1992 EXPOSURE
3.7 LAMP HEATER
[B]
[A]
This copier uses a fluorescent lamp [A] as the exposure light source. The
output of the exposure lamp varies depending on the temperature; low
temperatures especially degrade the light output. To prevent fluctuations in
temperature from affecting the copy image, the lamp heater [B] keeps the
lamp's temperature at 40°C.
