摘要： A continuous ink jet apparatus is provided. The apparatus includes a nozzle array with portions of the nozzle array defining a length dimension. A drop forming mechanism is positioned relative to the nozzle array and is operable in a first state to form ink drops having a first volume travelling along a path and in a second state to form ink drops having a second volume travelling along the path. A system applies force to the ink drops travelling along the path with the force being applied in a direction such that the ink drops having the first volume diverge from the path and at least one of the ink drops having the first volume and the second volume are rotated relative to the length dimension. At least a portion of the system is configured to rotate the ink drops relative to the length dimension. The system portion has a cross section and an outlet with the cross section having a first shape and a second shape. The second shape reduces the force along at least a portion of the outlet. The system portion can include a device positioned in the system and moveable between a first position and a second position such that the first cross sectional shape is created when the device is in the first position and the second cross sectional shape is created when the device is in the second position.

摘要： An ink jet printer and method capable of forming a plurality of registration marks on a receiver and sensing the marks formed thereby. The method includes a print head for printing an image of predetermined length on the receiver. The receiver has an image area for receiving the image therein and a border area adjacent to the image area. A marker forms the plurality of registration marks in the border area, so that the marks extend the length of the image. In addition, a sensor is disposed in sensing relationship to the marks for sensing the marks. The invention provides a combination marker for marking a receiver and a sensor for sensing the marks so that each image line is in registration with other lines of the image. Also, use of the invention avoids need for costly precision motors to advance the receiver during printing of image lines.

摘要： Drop deflector apparatus and methods for a continuous drop emission system comprising a plurality of drop nozzles emitting a plurality of continuous streams of a liquid that break up into streams of drops of substantially uniform drop volume having nominal flight paths that are substantially within a nominal flight plane are disclosed. A plurality of path selection elements corresponding to the plurality of continuous streams of drops is provided operable to firstly deflect individual drops from the corresponding continuous stream of drops along a first deflection flight path diverging from the nominal flight path based on pattern data. A plurality of gas nozzles is provided which generate a plurality of localized gas flows, positioned along one of the first deflection flight paths or the nominal flight paths, wherein the localized gas flows are oriented so as to cause a substantial second deflection of one of the firstly deflected drops or the nominal drops in a direction perpendicular to the nominal flight plane without causing a substantial deflection of drops following the other of the first deflection flight paths or the nominal flight paths. Secondly deflected drops are captured before they impinge a receiver medium. An image pattern is thereby deposited by either firstly deflected or undeflected drops.
