Roger E. Kuseski - Longmont CO
Terence Travis - Boulder CO

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

G03B 2732

US Classification:

355 24

Abstract:

Copy production machine having a print mode for making copies under automatic control interruptible by a copy mode of making copies. In the print mode images to be copied are automatically supplied to a copy production portion. In the copy mode, a variety of image supplying techniques may be employed. Copy output means separate copies made from the two modes. In the print mode images are preferably precollated whereas in the copy, mode produced copies are collated. In a print mode plural image sources may be employed, such sources being activated ad seriatim.

Abstract:

A method and apparatus are disclosed for electronic collation of sheets of a recording medium, such as paper, printed on one or both sides from electrical signals received at a printer. For printing multiple sets on one side only, the signals are written into a memory in the order in which they are received. The first set may be printed in the desired page order on a recording medium fed through the printer as the signals are received. Additional sets are printed in the same page order by writing the contents of the memory into the printer as many times as necessary as the recording medium is fed through the printer. For printing multiple sets on both sides, the signals representative of every other page are written into the memory and organized into two ordered sequences. One of these sequences contains the electrical signals representative of each of the pages to be printed on one side of the recording medium and the other sequence contains the electrical signals to be printed on the other side of the recording medium. Within each sequence the order of the signals is such that the signals representative of adjacent pages in the order to be printed are adjacent one another in the sequence.
