  • Patent number: 9087601
    Abstract: Techniques disclosed herein may prevent program disturb by preventing a select transistor of an unselected NAND string from unintentionally turning on. The Vgs of a select transistor of a NAND string may be lowered from one programming pulse to the next programming pulse multiple times. The select transistor may be a drain side select transistor or a source side select transistor. Progressively lowering the Vgs of the select transistor of an unselected NAND string as programming progresses may prevent the select transistor from unintentionally turning on. Therefore, program disturb is prevented or reduced. Vgs may be lowered by applying a lower voltage to a select line associated with the select transistor. Vgs may be lowered by applying a higher voltage to bit lines associated with the unselected NAND strings as programming progresses. Vgs may be lowered by applying a higher voltage to a common source line as programming progresses.

  • Patent number: 8773902
    Abstract: In a non-volatile storage system, a programming portion of a program-verify iteration has multiple programming pulses, and storage elements along a word line are selected for programming according to a pattern. Unselected storage elements are grouped to benefit from channel-to-channel capacitive coupling from both primary and secondary neighbor storage elements. The coupling is helpful to boost channel regions of the unselected storage elements to a higher channel potential to prevent program disturb. Each selected storage element has a different relative position within its set. For example, during a first programming pulse, first, second and third storage elements are selected in first, second and third sets, respectively. During a second programming pulse, second, third and first storage elements are selected in the first, second and third sets, respectively. During a third programming pulse, third, first and second storage elements are selected in the first, second and third sets, respectively.

  • Patent number: 8517503
    Abstract: An object of the present invention is to appropriately dispense treatment fluid to wipers, and to always wipe ejection-orifice formation surfaces in a favorable state regardless of an environmental change and the like. To this end, in the present invention, a treatment-fluid holding portion holds treatment fluid used in a wiping operation of wipers. When the wipers contact the treatment-fluid holding portion, the treatment fluid is transferred to the wipers. In an environment where the treatment fluid is thickened, the wipers with ink dispensed thereto are brought into contact with the treatment-fluid holding portion to supply ink to the treatment-fluid holding portion. Thus, the viscosity of the treatment fluid near a contact portion between the treatment-fluid holding portion and the wipers decreases, and the treatment fluid is sufficiently transferred to the wipers.

  • Patent number: 8511779
    Abstract: By suppressing deviation of dot-formation positions stemming from insufficient accuracy in conveying a printing medium due to eccentricity of a conveying roller, a printed image in which unevenness is less visible is obtained. An accumulated amount of conveyance errors is decreased by narrowing a nozzle-use range and reducing a conveyance amount over an entire printing region according to a mode used for printing an image in which the coverage of a printing medium is low due to a small number of ink colors to be used, for example, a mode used for printing a monochrome image by using a black ink dominantly in all of the density regions.

  • Patent number: 8511787
    Abstract: The sequence of the acquisition of a correction value of a conveying error depending on the eccentricity of the conveying roller (correction value for eccentricity) and the acquisition of a correction value of a conveying error depending on the outer diameter of the roller (correction value for outer diameter) is considered to acquire a precise correction value for outer diameter. A test pattern to acquire the correction values for eccentricity and for outer diameter is formed with an area exceeds the area corresponding to an integer multiple of the circumferential length of the roller. The correction value for eccentricity and that for outer diameter are acquired in this sequence. The fluctuation in the conveying error is reduced by the application of the correction value for eccentricity, and the influence of the excess area is made smaller before the correction value for outer diameter is acquired by averaging the conveying errors.

  • Patent number: 8439472
    Abstract: While a conveying error of a roller depends on the eccentricity of the roller, the amount and the state of the eccentricity sometimes makes the roller have different conveying errors from one point in the longitudinal direction of the roller to another. There is provided a construction for obtaining a correction value that is suitable for the correction of the conveying error even in such a case as described above. To this end, plural test patterns are formed in the longitudinal direction of the roller. Then, a suitable correction value for correcting the conveying error that depends on the eccentricity of the roller is obtained on the basis of these test patterns.

  • Patent number: 8251479
    Abstract: The present invention aims to obtain preferable correction values to correct the conveying error of a conveying roller in accordance with the size of a printing medium, even when the conveying error caused by the eccentricity of the roller varies from a point to another in the longitudinal direction of a roller, depending on the amount and the state of eccentricity of the roller. To achieve this object, correction values are acquired using the whole part of or only a part of plural test patterns formed in the longitudinal direction of the roller. The correction values thus acquired correspond to the respective zones where the test patterns are formed.

  • Patent number: 8079659
    Abstract: Provided are a printing apparatus and a conveying-error controlling method capable of printing a high-quality image by correction reflecting the conveying amount of a printing medium. A provided inkjet printing apparatus prints images by printing scans for actual printing and by conveying the printing medium with a roller orthogonally to the printing-scan direction. In each printing scan, the printing medium is scanned with a print head having an array of nozzles from which the ink is ejected. The print head moving direction differs from the arranging direction of the nozzles in the array. The apparatus includes a conveying controller to control the conveying of the printing medium on the basis of a correction value used to correct a conveying error of the roller. The conveying controller changes the correction value to be applied in accordance with the conveying amount of the printing medium between two scans with the print head.

  • Patent number: 7963624
    Abstract: Performed is conveying-error correction in accordance with the kind and the number of rollers that are actually involved in the conveying of a printing medium. Each of the rollers that are potentially involved in the conveying of the printing medium has a unique amount of eccentricity, and may affect the quality of image to be printed in a peculiar manner. To address this problem, a surface of the printing medium is divided into areas according to the number and the combination of the rollers that are actually involved in the conveying. A pattern each is printed for each of the areas thus formed while the pattern enables the detection of the conveying error. A correction value to correct the conveying error is calculated using each of the patterns. The correction values thus obtained are reflected in the conveying of the printing medium.
