摘要： An ink jet print head is formed of a silicon substrate that includes integrated circuits formed therein for controlling operation of the print head. The silicon substrate has a series of ink channels formed therein along the length of the substrate. An insulating layer or layers overlying the silicon substrate has a series of nozzle openings or bores formed therein along the length of the substrate and each nozzle bore communicates with a respective ink channel. A primary heater element is associated with each nozzle bore for asymmetrically heating the ink in the nozzle bore. A secondary heater element is provided upstream of the primary heater element and formed in the insulating layer to preheat ink just prior to entry of the ink into the nozzle bores.

摘要： An ink drop deflector mechanism is provided. The ink drop deflector mechanism includes an ink drop source and a path selection device operable in a first state to direct drops from the source along a first path and in a second state to direct drops from the source along a second path. The first and second paths diverge from the source. The mechanism also includes a system which applies force to drops travelling along at least one of the first and second paths with the force being applied in a direction so as to increase the divergence of the paths. The mechanism may include a gas source which generates a gas flow force that is applied in a direction that increases the divergence of the paths. The gas flow may be positioned between the first and second paths. The gas flow may be substantially laminar and interact with at least one of the first and second paths as the gas flow loses its coherence. The mechanism may also include a catcher with at least a portion of the system being positioned adjacent the catcher. Alternatively, at least a portion of the system may be integrally formed in the catcher.
