    摘要: For each totally black pixel of image data to be printed using a fluid-ejection printing device, it is determined whether the pixel is part of a line feature or an area fill feature of the image data. Where the pixel is part of a line feature, a first printing mask selected that is optimized for printing line features. Where the pixel is part of an area fill feature, a second printing mask is selected that is optimized for printing area fill features. Each mask specifies a number of fluid droplets to be printed and positions where the fluid droplets are to be printed. The selected mask is applied to the pixel. The pixel is printed using the mask that has been applied. The fluid-ejection printing device prints the pixel by ejecting the number of fluid droplets specified by the mask at the positions specified by the mask.

    摘要: Detachable fastening system between a male piece (2) and a female piece (1), pin (3) and female piece (1), specifically for use in machines for moving earth and stones. It is formed by a tooth (2) with a transverse aperture, a tooth holder (2) with another transverse aperture, a pin with an intermediate nipple, and an elastic tensor (4) located in a complementary cavity of the tooth holder (2). The penetration and subsequent rotation of the pin (3) immobilizes it axially, as it is held in said angular position by the action of the tensor (4). In addition, the pin (3) has at one end a projection that interacts with a groove ramped helicoidally and fitted in the aperture of the tooth in order to absorb the axial forces, by unloading the tensor (4) thereof, and also in order to limit the angular distance travelled by the pin between the blocking and unblocking positions, and in order to facilitate possible extraction thereof.

    摘要: In a method for printing a plurality of pixels, each pixel of a plurality of pixels is printed by controlling an inkjet print head to provide for each pixel at least two ink drops at different positions in a print head movement direction, the print head having a plurality of trenches supplying ink to a plurality of sets of nozzles. The at least two ink drops forming first pixels of said plurality of pixels are fired from the same trench.

    摘要: A multipass printing method includes determining at the end of a printing pass if at least some dot depositing elements of at least one printhead require a servicing operation. In case the determination is positive, the method includes printing at least one incomplete printing pass in which at least the dot depositing elements of the at least one printhead that require a servicing operation are not operated to print. At the end of the incomplete printing pass, the method includes servicing at least the dot depositing elements of the at least one printhead and printing at least one compensating printing pass, which adds to the information to be printed in the compensating printing pass at least part of the information that failed to be printed by the dot depositing elements of the at least one printhead in the at least one incomplete printing pass.

    摘要: A page wide array printer comprises a print head bar which carries an array of print nozzles, and which is static during a printing operation. A carriage has print head service elements. The print head bar is movable perpendicularly to the plane of the print medium beneath the print head, between a lowered print position and a raised service position. The carriage is moveable along the print head to perform a service operation when the print head is in the raised position.

    摘要: A method of printing a document using one of a plurality of print modes, the method comprising: (i) notionally dividing a digital image of the document into sectors; (ii) for each sector, comparing one or more properties of the luminosity of pixels within each sector with one or more threshold values; (iii) using the comparison of (ii) to determine whether each sector is likely to show an image defect if printed at a lower image quality print mode; (iv) selecting a print mode such that all sectors are determined not to be likely to show an image defect; (v) printing the document using the determined print mode.
