Abstract
The distribution environment of printer products creates a lot of shocks. The shock causes a variety of malfunctions in the printer. Among them, toner leakage problem is the most difficult problem to solve. Multiple drop tests were conducted to find some causes of toner leakage. However, there are many limitations because toner particle size is too small. In this study, to overcome these limitations and inefficiency of development process, the new simulation method is introduced. This method is developed for predicting toner leakage, and 1-way coupling analysis technology is used between structural analysis solver(LS-DYNA) and particle analysis solver (Metariver DEM) to make a toner leakage phenomenon visible.
