    摘要： The present invention is embodied in a system and method for using lower data rates (312) and less memory, for high nozzles per inch printheads (110). The printing system (100) of the present invention includes a printhead assembly (110) and an ink supply (112) for printing ink on print media (114). The printhead assembly (110) includes a printhead body, ink channels (121), a substrate, such as a semiconductor wafer, a nozzle member (120) and a barrier layer located between the wafer and nozzle member (120). The nozzle member (120) has plural nozzles coupled to respective ink channels (121) and is secured at a predefined location to the printhead body with a suitable adhesive layer. The printhead (110) has a controller (116) which can be firmware, software or any suitable processor that can control the ejection of ink from the plural nozzles. The controller (116) can be defined in the integrated circuit as receiving data stored in the data in the buffer memory (302), assigning primitive addresses (308) in the heater array from the data, and determining the firing pulse rate of the heater elements (117) in the heater array so as to maintain accuracy and precision of ink droplet placement by simultaneously limiting the number of nozzles firing and decreasing a data rate of firing of each nozzle. The controller (116) can be created by any suitable integrated circuit manufacturing or programming process.

    摘要： An inkjet printing mechanism (10) has multiple inkjet printheads (26a, 26b) which controllably eject multiple ink droplets, and has a carriage (22) to carry the printheads. The carriage is designed to move the printheads through a print zone to a service station (16) where the printheads are serviced. During a servicing mode of operation, the printheads (26a, 26b) eject ink droplets at the service station (16) to clear the orifices of the nozzles of the printheads prior to printing. A reservoir (30) is provided at the service station to collect the ink droplets ejected from the printheads during the servicing mode. Multiple chimneys (34, 36) receive ink from the multiple printheads and guide ink from different printheads to different areas of the reservoir (30). Precipitates that may form when different inks combine are kept away from the chimneys.

    摘要： The present invention is embodied in a system and method (100) for producing efficient ink drop overlap filled with a pseudo hexagonal grid pattern. In general, the present invention can include an inkjet printhead assembly (110) that incorporates a preprogrammed correction scheme or schemes [1-n] (704) (herein correction scheme will refer to all applications), for correcting systematic ink drop placement errors of the inkjet printhead (110). The printing system (100) of the present invention uses a unique ink dot pattern, called a pseudo-hexagonal close pack system. The present invention optimizes the addressable grid for dot placement, pseudo hexagonal close pack system, with an efficient geometry for packing circles to fill an area, similar to the hexagonal close pack system. However, the present invention in creating dots on a non-symmetric grid is supported by available software and is not computationally complex.
