Abstract:
An image-forming device forms an image having improving image quality by conveying a sheet in a nonuniform conveyance, and reduces a processing load required for calibrating a conveying length for the recording medium. In an image-forming device, a process for acquiring a theoretical conveying length for conveying a recording medium (S404) and for calibrating the theoretical conveying length (S409) is only executed for a large feed used to convey the recording medium a second conveying length greater than a first conveying length (S405: YES) and not for small feeds used to convey the recording medium the first conveying length (S405: NO). Since calibration is performed on the second conveying length, which is greater than the first conveying length, this method reduces a decline in precision for the conveying length of the recording medium, even when reducing the number of calibrations.
Abstract:
An inkjet recording device records images by forming dots on a recording medium with droplet modulating method. The inkjet recording device includes a recording unit, a multilevel-data creating portion, and a dot-layout-data creating portion. The recording unit ejects ink droplets for forming dots at corresponding pixel positions. The recording unit is capable of changing a volume of each ink droplet to form dots with different sizes. The multilevel-data creating portion creates multilevel data based on image data. The multilevel data includes a dot size for each dot. The dot-layout-data creating portion creating dot layout data based on the multilevel data, so as to prevent the recording unit from forming dots having the same size continuously by greater than or equal to a predetermined number. The recording unit performs recording operation based on the dot layout data.
Abstract:
If the subject pixel density I is the minimum density (0), the input conversion portion H1 controls the output conversion portion H4 to output a level of OFF. If the subject pixel density I is the maximum density (255), the input conversion portion H1 controls the output conversion portion H4 to output the other level of ON. The input conversion portion H1 outputs the imaginary density A of one (1) to the input modification portion H2 if the subject pixel density I is the minimum density of zero (0). The input conversion portion H1 outputs the other imaginary density B of 254 to the input modification portion H2 if the subject pixel density I is the maximum density of 255. The conversion portion H3 compares, with the threshold value, a modified value I′ supplied from the input modification portion H2. Even in the uniform density region having the density of zero (0) or 255, the comparison judgment attained by the conversion portion H3 will frequently change. The calculation process attained by the binary error generating portion H5 will frequently switch between two types of calculation processes (2) and (3). Uniformity in conversion errors distributed from the error distributing portion H6 to the error storing portion H7 is disturbed. Pixels will be turned On and OFF irregularly, thereby preventing occurrence of undesirable textures.
Abstract:
A printer having an adjusting apparatus for adjusting a head gap between a print head and a print sheet supported on a platen, is disclosed. In such printer, at first, a carriage 1 mounting the print head 8 thereon is advanced to the print sheet 6 by eccentrically rotating a guide bar 3 passed through a slide hole 1a with a solidable lubricant therebetween through a step motor 12 until a ribbon mask 9 contacts to the print sheet 6. And a drive pulse number Nm, which is input to the step motor 12 until the ribbon mask 9 contacts to the print sheet 6 and corresponds to moving distance of the carriage 1 from a standard position O, is calculated. Further, a value Na (=N1-Nm) representing a drive pulse number for the step motor 12 corresponding to a thickness of the print sheet 6, is calculated. Here, the N1 is a drive pulse number necessary to advance the carriage 1 toward the platen 2 till the ribbon mask 9 contacts to the platen 2 in case that the print sheet 6 is not supported on the platen 2 and stored in a NVRAM 29. Next, it is judged whether the calculated Na is bigger than or equal to a NaO which is stored in a ROM 25 and corresponds to a drive pulse number for the step motor 12 necessary to obtain the optimum gap between the print head 8 and the print sheet 6 when the print sheet 6 with 0.4 mm thickness is utilized.
Abstract:
A control device may generate processed image data, supply the processed image data to a print performing unit and execute a compensation process on a target pixel by using correcting data for a target image forming element which is to form an image at a position corresponding to a target pixel. The correcting data may be data acquired by using a difference between a target value and a value being acquired by using characteristic data corresponding to a first image forming element within a plurality of image forming elements. The target value may be acquired by using characteristic data corresponding to the target image forming element. The first image forming element may be an image forming element which is to form a first neighbor raster neighboring a target raster formed on the print medium by the target image forming element.

A scanning unit is configured to move the recording head back and forth in a second direction perpendicular to the first direction. A setting unit is configured to set process pixels in an input image by rendering at least one of the plurality of recording elements disabled so as not to form dots and at least another one of the plurality of recording elements enabled to allow dots to be formed in each of a plurality of columns of a recording medium. A dot data generating unit is configured to generate dot data by applying a weight matrix to the density data of the process pixel. The dot data is applied to the recording head to form dots on the recording medium.
Abstract:
A binary conversion error value as to neighboring pixels stored in an error value storage portion is added to a pixel density of a subject pixel, which is read from an input image storage portion, at a ratio based on an error distribution matrix, so that a modified density is calculated. A determination is made as to whether the modified density is greater than or equal to a threshold value, and an output image is binarized based on the determination, and stored in an output image storage portion. An output density, which is a value of the output image for calculating the binary conversion error value, is set to a value corresponding to a print mode currently set. By subtracting the output density from the modified density, the binary conversion error value generated in the binarization process for the subject pixel is calculated.
Abstract:
An ink-jet recording apparatus including: a cartridge mount; a recording head; an ink passage; an ink discharger; and a controller. An ink cartridge that stores ink is to be replaceably mounted on the cartridge mount. The recording head ejects the ink toward a recording medium. Through the ink passage, the ink is supplied from the cartridge mount to the recording head. The ink discharger discharges the ink. The controller includes a cartridge judgment section and a discharger control section. The cartridge judgment section judges whether the ink cartridge mounted on the cartridge mount is a subject cartridge that satisfies a predetermined condition or not. The discharger control section controls the ink discharger to discharge at least the ink in the ink passage when the cartridge judgment section has judged that the ink cartridge mounted on the cartridge mount is the subject cartridge.
