摘要：A reproduction apparatus such as a copier/printer includes a plurality of jobimage buffers (JIBs). Each JIB includes a compressor for compressing rasterized imagedata, a memory store for storing compressed rasterized image data and an expander forexpanding the compressed rasterized image data. An electronic writer has a plurality ofwriting components, with each component being associated with a respective segment ofan image to be simultaneously recorded. A writer interface is operatively connected tothe JIBs and the writing components for simultaneously outputting to the writingcomponents data for a respective image segment to be recorded by its respectivewriting component. A controller controls flow of data to the JIBs so that each of theplural JIBs receives data for only one respective segment of each page of image data.The controller determines which of the JIBs has the most available memory capacity forstoring a segment of a page and directs flow of data of a segment of a page meeting acriterion as most busy to the JIB determined to have the most available memory capacity.In an alternative embodiment, the controller rotates the assignment of control segmentsof pages to different JIBS so that the center segments, which are likely to be the busiestsegments and thus least compressible, are not assigned always to the same JIB.
