    摘要: A fluid ejection device and a printhead including one or more such fluid ejection devices are provided. The fluid ejection device includes a substrate having a first nozzle array and a second nozzle array, each array having a plurality of nozzles and being arranged along a first direction, the first nozzle array being arranged spaced apart in a second direction from the second nozzle array. A first fluid delivery pathway is in fluid communication with the first nozzle array, and a second fluid delivery pathway is in fluid communication with the second nozzle array. Nozzles of the first nozzle array have a first opening area and are arranged along the first nozzle array at a pitch P. Nozzles of the second nozzle array have a second opening area, the second opening area being less than the first opening area. At least one nozzle of the second array is arranged offset in the first direction from at least one nozzle of the first array by a distance which is less than pitch P. A printhead comprises one or more such fluid ejection devices arranged on a support member.

    摘要: An inkjet printer and printing method for improving print quality. The printer minimizes the visually perceptible effect of dot placement errors, dot size errors, and dot shape errors on a printed medium due to depositing drops of ink from lower print quality printhead nozzles. The printer provides a sensor which can test the ink drop output of the printhead nozzles to determine, for each particular printhead installed in the printer, which nozzles are of higher print quality and which are of lower print quality. A printmask is then defined based on the results of the testing for use in printing from that printhead. The printmask has a mask pattern which enables the deposition of more ink from higher quality nozzles and less ink from lower quality nozzles. Such a printer improves print quality without reducing throughput.

    摘要: A method for monitoring the condition of an inkjet printhead. A test image is printed by the printhead and a second reference printhead. The density of ink dots in the test image is selected so that each dot just contacts adjacent dots while avoiding significant overlap. A defective nozzle can produce misplaced or undersized dots, creating abnormal spacing between adjacent dots. At the selected ink dot density, the abnormal spacing is most perceptible to the eye.

    摘要: A swath printer and multipass printing method for improving print quality. The printer minimizes dot placement errors on a printed medium due to depositing drops of ink from lower quality printhead nozzles by providing a printmask having a mask pattern which prints with those nozzles most susceptible to dot placement error using a hi-fipe printmode which deposits into a specific pixel location a small number of drops in each of multiple passes, and a multidrop printmode which deposits into a specific pixel location many drops rapidly in one of the passes. Because such a printer and method prints substantially equally with all printhead nozzles, it does not shorten the useful life of the printhead due to defects associated with the number of times a nozzle deposits ink.

    摘要: A method providing for the exercise of one or more nozzles of an inkjet print head and simultaneously forming fiducial registration marks on a sheet of print medium. The exercising and forming of the fiducial registration marks both occur in the course of forming inkjet printed images on the sheet of print medium so that the prints and fiducial marks are in registry. Preferably exercising of the nozzles occurs at the beginning and end of each pass of the print head so that there are two such fiducial marks, one along each lateral edge of the image. A segment of a print medium including printed images and a fiducial mark composed of the exercise of the inkjet print head nozzles is also disclosed.
