    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.

    摘要: In order to reduce particle clogging of ink firing chambers in an inkjet printer printhead, the barrier layer is configured to have a plurality of inner barrier islands, each associated with a respective one of the heater resistors, disposed between an ink firing chamber and the ink plenum, to form two ink feed channels. The two ink feed channels are designed to have a right angle turn to prevent particles from entering the ink firing chamber. A plurality of outer barrier islands, having a number equal to twice the number of inner barrier islands, are disposed between the inner barrier islands and the ink plenum, and are configured in lines parallel to the lines of heater resistors to prevent particles from reaching the ink feed channels.

    摘要: A printhead for an inkjet printer employs non-circular orifices, such as oval or parallelogram, at the surface of the orifice plate to increase the restoring force of the ink meniscus. The reduced tail and diminished spray of an ink droplet expelled from the non-circular orifice results in improved edge roughness and improved quality of print.
