Abstract
An electrographic system comprises a graphics surface assembly having a graphics surface integrally coupled to a memory device which contains calibration data designated for the graphics surface. During manufacturing, the memory device is mounted onto an interface board which is attached to the graphics surface through a flex cable. A calibration procedure is performed on the graphics surface whereby calibration data is generated and stored in the memory device. The memory device, loaded with the calibration data, is thereafter linked to its associated graphics surface.
