Warm-up controller for a scanner light-source
Abstract
An apparatus for connecting electrical power [130] to an exposure lamp [145] in a scanner [140] at selected times. By automatically turning the scanner on and off at selected times, such an apparatus provides an apparent reduction in exposure lamp warmup time, with associated improvement in operator productivity, while minimizing lamp operational life degradation and excessive energy consumption caused by leaving the lamp turned on.
