Abstract
Abstract A technique to identify colorimetric properties of toner contained within a cartridge in a reproduction machine by embedding in a PROM within the cartridge specific coordinates of a color coordinate system and entering the color coordinate information into the data base of the machine to accurately map color data from one color domain such as a full color domain to another color domain such as a highlight color domain.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
137 words
A reproduction machine comprising a developer cartridge for developing color images, a control including a decoder for mapping colors from one color space to another color space within the machine, a card attached to the developer cartridge including address, power and control line contacts electrically connected to the decoder, a memory device supported by the card, the memory device identifying within the cartridge specific coordinates of a color coordinate system, the decoder conveying the color coordinate information from the memory device to the control of the machine for mapping colors from one color space to another color space, a connector, one side of the connector coupled to the decoder, the other side of the connector coupled to the memory device, the connector coupling the address, power and control line between the memory device and the machine control.
