摘要
A power saving apparatus and method for imaging modules in a variable data lithography system is provided. The imaging modules are arranged adjacent to each other to project a scan line of imaging data on a rotating imaging member in a variable data lithography system. The imaging module includes a look ahead buffer which stores imaging data and from which the stored data is read out for projection on the imaging member. The power saving apparatus uses an image look ahead concept to save part of the power consumed in the imaging modules in the projection mode of operation by selectively powering each laser source based on the imaging data in the look ahead buffer.
