Abstract: A method of printing from a fixed inkjet printhead having a plurality of ink planes. The method includes the steps of: feeding a print medium past the printhead in a media feed direction, the media feed direction defining relative upstream and downstream sides of the printhead; printing an image onto the print medium, the image being defined by image data;and printing a keep-wet pattern onto the print medium from each ink plane of the printhead, the keep-wet pattern being defined by a plurality of dots printed at a frequency sufficient to maintain hydration of each nozzle in the printhead. A first keep-wet pattern from a first ink plane is printed at a higher frequency than a second keep-wet pattern from a second ink plane, the first ink plane being furthest upstream in the printhead.

Abstract: A method of generating print data for an inkjet printhead having a plurality of ink planes. The method includes the steps of: receiving image data for a print job in a printer controller; retrieving keep-wet pattern data for each ink plane of the printhead, the retrieved keep-wet pattern data being determined using one or more input parameters; generating first print data for each ink plane in the printer controller based on the received image data; merging the first print data with the keep-wet pattern data to provide second print data for each ink plane; and sending the second print data from the printer controller to the printhead, thereby causing the printhead to print an image together with a keep-wet pattern. The keep-wet pattern is defined by a plurality of dots printed at a frequency sufficient to maintain hydration of each nozzle in the printhead.

Abstract: A process for filling one or more etched holes defined in a frontside surface of a wafer substrate. The process includes the steps of: (i) depositing a layer of a photoimageable thermoplastic polymer onto the frontside surface and into each hole; (ii) reflowing the polymer; (iii) selectively removing the polymer from regions outside a periphery of each hole, the selective removing comprising exposure and development of the polymer; (iv) optionally repeating steps (i) to (iii) until each hole is overfilled with the polymer; and (v) planarizing the frontside surface to provide one or more holes filled with a plug of the polymer. Each plug has a respective upper surface coplanar with the frontside surface.

Abstract: An ink delivery system for an inkjet printer includes: a positive ink line; a negative ink line; and one or more print modules interconnected between the positive ink line and the negative ink line. Each print module includes: an inlet port; an outlet port; a printhead interconnected between the inlet port and the outlet port; a control valve positioned at the inlet port for controlling an ink pressure in the printhead; an ink pressure sensor for sensing an ink pressure in the print module; and a controller for receiving feedback from the pressure sensor and controlling the control valve. During printing, the ink pressure sensor, the controller and the control valve cooperate to control a backpressure in the printhead within a predetermined backpressure range.

Abstract: A printer having a beltless guide for guiding print media around a curved media feed path. The guide includes: first and second opposed guide surfaces for guiding print media therebetween; and a chicane corresponding to a point of inflection in the curved media feed path. The media path does not follow a curvature of the chicane and the chicane is configured to transfer print media from contact with the second surface to contact with the first surface or vice versa.
