When pigmented ink is used in inkjet printer, the first drop is sometimes failed to fly after a short intermission of one minute or so. At the first time, the cause of this phenomenon was considered as the dispersion liquid evaporation or the dispersed pigment sedimentation. These answers were denied, however, because of their extremely slow rate response. The simulations for the pigment particles diffusion have been studied by using the Neumann type boundary condition for the liquid evaporation from the ink surface. The derived conclusion is that the dispersed particles are rapidly condensed and packed on the air-liquid interface on a certain condition. It is supposed that the thin film formed on the liquid surface affects the inkjet dynamics, and the misfire is induced.
