Latest Patents

Lehane's latest patents include a print chip configured for single-pass monochrome printing at high speeds. This innovative print chip features an elongate silicon substrate that defines nominal leading and trailing longitudinal sides. It incorporates circuitry layers positioned on the silicon substrate, along with a MEMS layer that contains multiple parallel nozzle rows. Each nozzle row is designed with a plurality of inkjet nozzle devices arranged in both a main row portion and a dropped row portion, which is offset from the main row portion. The circuitry layers are equipped with data latches that provide dot data for the inkjet nozzle devices.

Another notable patent is a method for single-pass monochrome printing at high speeds. This method involves printing an image from a printhead module that has several horizontal nozzle rows. Each nozzle row consists of a main row portion and a corresponding dropped row portion that is vertically offset. The method includes determining a predetermined delay for the dropped row portions based on the offset, print speed, and print resolution. It also involves allocating dot data for image lines to respective nozzle rows and firing nozzles from both the main and dropped row portions in a predetermined sequence.
