Abstract
We have previously reported in a keynote speech at NIP13 that in Japanese analogue PPC market, the average monthly copy volume (AMCV) is proportional to the square of the speed (copies per minute) of PPCs, and the mean copies between service visits (MCBV) is proportional to the half power of the AMCV. In this paper, the analyses is extended to include European market data and to consider the average number of original documents per month, the average number of pages per original document and the installation rate of automatic document feeders. The background for the validity of the above-mentioned empirical laws in copy-and-distribute offices is elucidated, and the average number of pages per original document is determined to be 2.2. For the distribute-and-print offices, the average monthly print volume (AMPV) and the mean prints between service visits (MPBV) are investigated from the view points of the mission of the office, the principle of office structures and the information media used in the offices. We predict new relationships that the AMPV is linearly proportional to the print speed and the MPBV is constant independent of the AMPV. This suggests a more severe challenge for the hardcopy business.
