20090066750 | Forceless support frame for printhead shuttle in digital printers - In a digital printer the elements involved directly in the print process, which are located on a shuttle assembly are mounted upon a metrological frame which is isolated from the base frame by vibration dampers. Because the elements of the shuttle drive systems, such as a belt drive system having a motor and pulleys, are mounted upon the base frame, the drive and reaction forces from the motor drive systems are led to the base frame while the shuttles assembly is guided by the force-free, vibration free metrological frame. This allows for higher accuracy during printing as the metrological frame serves as a vibration free reference element. | 03-12-2009 |
20090211469 | Double shuttle configuration for digital printers - A printhead positioning system is provided wherein the shuttle assembly is split up in a printing shuttle, having a high accuracy positioning capability and a utility shuttle needing only a low accuracy positioning system. Due to this split-up the mass of components which have to be positioned accurately is greatly reduced and therefore making it easier to position the lighter load accurately and allowing for use of cheaper drive systems while maintaining the high accuracy in printing. | 08-27-2009 |
20090231374 | METHOD AND APPARATUS FOR AUTOMATICALLY ALIGNING ARRAYS OF PRINTING ELEMENTS - A method and apparatus for aligning the printing of dots generated by at least one array of printing elements of a printing apparatus. The method includes the steps of printing a calibration test pattern, scanning the printed calibration test pattern, determining at least one calibration value based on the scanned calibration test pattern, and adjusting the alignment of the array of printing elements based on the determined calibration value. The step of scanning the printed calibration test pattern further includes automatically positioning a camera relative to the printed calibration test pattern and imaging a detail of the printed calibration test pattern within the field of view of the camera. | 09-17-2009 |
20090303276 | Collision avoidance measure and sensor - To avoid possible damaging collisions of a printhead with small receiver defects and other obstacles in a digital printer using a printhead mounted on a scanning shuttle for recording an image on a receiver while scanning along the receiver, a method using the following steps is used:—sensing for possible obstacles having a size smaller and larger than the inkjet head-receiver clearance distance in an area of the receiver to be scanned over by the printhead using a sensor system mounted on the scanning shuttle,—avoiding a collision of the printhead with the obstacle when an obstacle is sensed. Preferably an evaluation step is include to evaluate is a detected obstacle is evaluated to be potentially damaging. A system for using the steps is also disclosed. | 12-10-2009 |
20100002050 | PRINT HEAD MOUNTING ASSEMBLY AND METHOD FOR MOUNTING A PRINT HEAD ONTO A CARRIAGE FRAMEWORK - A print head mounting assembly and a method of mounting and positioning a print head on a print head carriage framework suitable for mounting in a printing system includes a print head positioning device for receiving a print head, and a print head mounting tile having a mounting surface for mounting the print head positioning device. The print head mounting tile is adjustably mounted on the print head carriage framework such that it provides a mounting surface for the print head positioning device that is level with a reference printing surface, when the print head carriage framework is mounted in the printing system. The print head positioning device is adjustably mounted on the print head mounting tile such that the print head, being received in the print head positioning device, is accurately positioned on the mounting surface of the print head mounting tile. | 01-07-2010 |
20100039486 | INK DEGASSING FOR CIRCULATING INK SUPPLY SYSTEMS IN INK JET PRINTERS - An ink circulation system includes a supply subtank for supplying ink to an ink jet print head and a return subtank returning the ink not ejected by the ink jet print head. A print circulation path links the supply subtank with the ink jet print head and the return subtank for providing a print flow of ink from the supply subtank to the ink jet print head, the return subtank, and back to the supply subtank. A degas circulation path links the supply subtank with a through-flow degassing unit for providing a degas flow of ink from the supply subtank to the through-flow degassing unit and back to the supply subtank. The ink circulation system improves the degassing quality of the ink supplied to the ink jet print head of a printing apparatus is provided. | 02-18-2010 |
