Abstract
A piezoelectrically driven ink jet printer includes a shock absorbing mechanism positioned in the ink supply tube for minimizing the effects on the ink within the print head of physical shocks to the ink supply tube or ink supply cartridge. The shock absorbing mechanism includes a flow restriction device and a reservoir device arranged such that the physical performance of the shock absorbing mechanism is analogous to the electrical performance of an RC low pass filter.
