IPC分类号： B41J29393
摘要： A monitoring system monitors a pressure wave developed in the surrounding ambient environment during inkjet droplet formation. The monitoring system uses either acoustic, ultrasonic, or other pressure wave monitoring mechanisms, such as a laser vibrometer, an ultrasonic transducer, or an accelerometer sensor, for instance, a microphone to detect droplet formation. One sensor is incorporated in the printhead itself, while others may be located externally. The monitoring system generates information used to determine current levels of printhead performance, to which the printer may respond by adjusting print modes, servicing the printhead, adjusting droplet formation, or by providing an early warning before an inkjet cartridge is completely empty. During printhead manufacturing, an array of such sensors may be used in quality assurance to determine printhead performance. An inkjet printing mechanism is also equipped for using this monitoring system, and a monitoring method is also provided.

摘要： An ink jet print head having a substrate with an upper surface, and an ink supply conduit passing through the substrate. An array of independently addressable ink energizing elements are attached to the upper surface of the substrate. An orifice layer has a lower surface conformally connected to the upper surface of the substrate, and has an exterior surface facing away from the substrate. The orifice layer defines a plurality of firing chambers providing communication to the ink energizing elements, and each of the orifices is positioned in registration with a respective single ink energizing element. The exterior surface defines a plurality of nozzle apertures, each providing the upper terminus of a single firing chamber. Each of the firing chambers is laterally separated from all other firing chambers by a septum portion of the orifice layer.

摘要： A scalable wide-array printhead is formed by mounting multiple thermal inkjet printheads to a carrier substrate. The printheads are mounted to one face and logic ICs and drive ICs are mounted to an opposite face. Interconnects are formed through the carrier substrate to electrically couple the printheads to the logic ICs and drive ICs. The carrier substrate is formed of silicon and etched to define ink refill slots. A solder bump mounting process is used to mount the printheads to the carrier substrate. Such process serves to align each of the printheads. The solder forms a fluidic boundary around a printhead ink slot.

摘要： An inkjet printing device is arranged to employ a first set of multiple nozzle drop generators activated by a first address signal and a second set of multiple nozzle drop generators activated by a second address signal. The multiple nozzles of each drop generator of the first set are arranged in a predetermined geometric pattern, each of which encompasses at least one nozzle of a drop generator of the second set. The ink ejectors of one drop generator of the first drop generator set are arranged in subgroups, one subgroup of which shares a switched power return with one subgroup of ink ejectors of one drop generator of the second drop generator set.

摘要： A printhead includes at least a first drop generator set and at least a second drop generator set. The first drop generator set includes a first type of drop generator, whereas the other drop generator sets include a second type of drop generator. The first and second types of drop generators are primarily different with regard to the drop weights they are capable of providing. Preferably, the first type of drop generator comprises a multi-nozzle configuration, whereas the second type comprises single nozzle configurations. In one embodiment, a first type of ink is ejected by the first type of drop generators and a second type of ink is ejected by the second type of drop generators. To prevent unwanted mixing of the black and color inks, a first orifice or nozzle layer is provided separate and apart from a second orifice layer. In this manner, a single printhead may be used for the delivery of both black and color inks.
