  • Method and apparatus for split printing of color and monochrome documents
    Patent number: 6041200
    Abstract: 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.
