In doing research for developing future digital products, we have analyzed worldwide management data at our disposal that pertains to analog plain paper copiers (PPCs). According to our copy volume data, average monthly copy volume is proportional to the square of the speed (copies per minute) of PPCs. The result of our analysis of the copy volume data provides new information relating to such factors as the scale of offices and the workflow within them (factors influencing average monthly copy volume). The shift in the information infrastructure from a copy-and-distribute to a distribute-and-print model is discussed. According to our field service data, mean copies between service visits is proportional to the half power of the average monthly copy volume. The result of our analysis of the field service data provides new information relating to such factors as the level of technology represented by each PPC series (influencing mean copies between service visits). The copy volume business with field service in the copy market is discussed in light of our new knowledge about both copy volume and product reliability.
