Abstract
Abstract A system for providing a memory for storing electronic images with color mode marks and a control for providing images in optional color modes for producing a set of images with discrete elements of the set of images processed in a selected color mode independent of the color mode other elements. This is accomplished by identifying elements of the set of images with color code marks and responding to the color code marks to alter the operation of the machine dependent upon the identified color mode mark. The machine pitches are also changed to provide additional features such as simplex and duplex mode to selected images.

Claim 1
Independent Claim
204 words
In a machine having a control with memory for providing images in optional color modes determined by electronic color mode marks, the color modes being monochrome-black, monochrome-color, and highlight color, the method of providing a set of images with discrete elements of the set of images processed in a selected color mode independent of the color mode of other elements of the set of images including the steps of: transmitting electronic images with the electronic color mode marks to said memory, identifying the first element of the set of images with a first mark for a first color mode, responding to the first mark to provide the first element of the set of images in said first color mode, identifying a second element of the set of images with a second mark for a second color mode, and responding to the second mark to provide the second element of the set of images in said second color mode, the second mode being different than the first mode including the step of switching between simplex and duplex modes of operation including the step of delaying the scheduling of side 1 of a subsequent duplex page until side 2 of the current page has been imaged.

Claim 3
Dependent Claim
60 words
The method of claim 1 wherein the steps of responding to the first mark to provide the first element of the set of images in said first color mode, and responding to the second mark to provide the second element of the set of images in said second color mode include the steps of altering pitch cycles in the machine.
