    • A system for printing and copying color and black-and-white documents avoids the need for manual collating. The system provides N sets of documents using a printer and a copier, where each set of documents includes a first type of sheets (such as black-and-white sheets), and a second type of sheets (such as color sheets) provided in a particular sequence in relation to the first type of sheets. A first complete document set is printed, including the first and second types of sheets, along with N-1 insert sets of the second type of sheets, and an instruction sheet indicating the particular sequence. The first complete document set is positioned in a document feeder of the copier, and the N-1 insert sets are positioned in a post-process insertion tray of the copier. The copier is programmed using the instruction sheet to identify the particular sequence, and to output copies of the sheets of the first type from the first complete document set, and to output the sheets of the second type from the N-1 insert sets to replace the sheets of the second type in the first complete document set, thereby forming N complete document sets, in which the sheets of the second type are provided in the particular sequence.
    • 用于打印和复印彩色和黑白文档的系统避免了手动整理的需要。 该系统使用打印机和复印机提供N组文档,其中每组文档包括第一类型的纸张(例如黑白纸张)和第二类纸张(例如彩色纸张),其设置在 相对于第一类型的片材的特定顺序。 印刷第一个完整的文件集,包括第一和第二类型的纸张,以及第二类型的纸张的N-1个插入组,以及指示特定序列的说明书。 第一个完整的文档集位于复印机的文档进纸器中,并且N-1个插入组位于复印机的后处理插入托盘中。 使用说明书对复印机进行编程,以识别特定的顺序,并从第一个完整的文档集中输出第一种类型的纸张的副本,并从N-1个插入套件中输出第二种纸张以替换 在第一完整文件集中的第二类型的纸张,从而形成N个完整的文档集合,其中以特定顺序提供第二类型的纸张。

    • A method and apparatus are provided for compressing image data to enable the storage thereof in a limited amount of memory available in an imaging system. The image data is rasterized into a plurality of scan lines representing at least a portion of an image. Each scan line comprises a sequence of pixels. The scan lines are compressed in a first coding step. A determination is made as to whether the amount of data contained in the compressed plurality of scan lines exceeds the available storage capacity of the memory. If so, the scan lines are further compressed in a second coding step to reduce the amount of data therein. The second coding step can be successively repeated using more tolerant coding thresholds until the amount of data remaining no longer exceeds the available storage capacity of the memory.
    • 提供了一种用于压缩图像数据以使其能够在成像系统中可用的有限量的存储器中的存储的方法和装置。 图像数据被光栅化成表示图像的至少一部分的多条扫描线。 每个扫描线包括一系列像素。 扫描线在第一编码步骤中被压缩。 确定压缩的多条扫描线中包含的数据量是否超过存储器的可用存储容量。 如果是这样,则在第二编码步骤中进一步压缩扫描线以减少其中的数据量。 可以使用更宽的编码阈值连续地重复第二编码步骤,直到剩余的数据量不再超过存储器的可用存储容量。
