摘要： A scanning inkjet printing method comprises arranging a recording medium on a print surface; moving a carriage supporting at least one inkjet print head over the recording medium on the print surface in a scanning direction, while image-wise applying droplets of a liquid to the recording medium to form a first swath of printed dots on the recording medium; moving the recording medium and the carriage relative to each other in a transport direction, wherein the transport direction is transverse to the scanning direction; moving the carriage over the recording medium on the print surface in the scanning direction, while image-wise applying droplets of the liquid to the recording medium to form a second swath of printed dots on the recording medium; detecting a position of the first swath; determining a sub-carriage movement relative to the carriage in response to the detected position of the first swath to position the second swath relative to the first swath, wherein the sub-carriage is supported by the carriage and the movement comprises an amount of translation in the transport direction transverse to the scanning direction and an amount of rotation around a rotation axis, wherein said rotation axis is perpendicular to the print surface; and moving the sub-carriage in accordance with the determined amount of translation and the determined amount of rotation. Thus, the first and the second swath may be positioned accurately adjacent to reduce visibility of stitching inaccuracies between adjacent swaths.

摘要： A light beam position detecting device (38) detects the passage positions of a plurality of light beams for scanning the surface of a photosensitive drum. The light beam position detecting device (38) has a sensor pattern (S0) for generating an output which is continuously changed in a wide range with a variation in the passage position of the light beam in a sub-scanning direction perpendicular to a main scanning direction of the light beam. The sensor pattern (S0) precisely detects the relative scanning position of the light beam in a wide range. The passage positions of the plurality of light beams for scanning the surface of the photosensitive drum are controlled to a preset position based on the output of the sensor pattern (S0).

摘要： A method for correcting scanning errors in a shuttle scanner is described. A pattern sheet on which pattern data having a specified shape are recorded is scanned. Errors for incline of the pattern data are corrected by using pattern data of a straight line form among the scanned pattern data having the specified shape. Then, errors for distance between bands are corrected by using pattern data of a specified shape. Accordingly, since the errors for incline and the errors for distance between the bands can be corrected by using a computer program, correcting the errors of the pattern data is very simple. Furthermore, even if the scanner is subjected to an impact from an exterior, correcting the errors for incline and the errors for distance between the bands can be promptly performed.
