Title:
相変化インクにおける泡及びボイドを低減する圧力パルス
Document Type and Number:
Japanese Patent JP5785506
Kind Code:
B2
Abstract:
A phase change ink printer may be operated so that multiple pressure pulses are applied (1130) to the ink in an ink flow path of the printer during a time that the ink is changing phase. During the phase change, a portion of the ink in the ink flow path is in liquid phase and another portion of the ink is in solid phase. The pressure pulses are applied at least to the liquid phase ink in the ink flow path. The phase change may involve a transition from solid to liquid phase, such as during a start-up operation, or may involves a transition from a liquid phase to a solid phase, such as during a power down operation. Application of pressure during either of these operations serves to reduce bubbles and voids in the phase change ink.
