It is difficult to analyze the vibration and sound responses on a whole, surface and inside of a printer using FEM. This difficulty comes from the fact that almost the parts of the printer are made of plastic mold. In this investigation, statistical energy analysis (SEA) is applied to predict the responses on the printer unit. First, the selection of SEA subsystems is discussed using the initial slope ratio techniques. Then, an SEA model is constructed experimentally. The vibration energy level on each SEA subsystem predicted by the constructed SEA model is compared with the measured levels under impact test. It is shown that the vibration analysis on the printer unit is suitable for SEA.
