摘要:
To provide a printing method capable of inhibiting a paper sheet from being damaged at the time of conveyance and efficiently starting reprinting with high positional accuracy after printing is once stopped. The present invention is directed to a printing method of printing a unit image G by a printing part 2 based on detection of a reference punched hole 41 of a hole detection sensor 4 to form a print portion P1, then stopping printing to form a non-print portion P0, then by a mark detection sensor 3 detecting a register mark G2, recognizing a boundary between the print portion P1 and the non-print portion P0, and reprinting the unit image G from the non-print portion P0 based on detection of the reference punched hole 41 by the hole detection sensor 4.
摘要:
An apparatus is provided for processing a substrate on a support body. The apparatus comprises the support body, at least one registration member, a carriage unit and a controller. The support body is arranged for supporting the substrate. The at least one registration member is adapted for registering the substrate on the support body by engaging the substrate in contact to the at least one registration member, when the at least one registration member is arranged into a registering state. The carriage unit is movably arranged relative to the support body for processing the substrate. The control unit is arranged for executing the steps of: a) selecting a position of the substrate on the support body; b) selecting a first registering position on the support body of a first registration member for registering the substrate at the selected position on the support body in the registering state, when engaging the substrate in contact with the first registration member being arranged in the first registering position; and c) moving the carriage unit relative to the support body to a processing position for processing the substrate, when the substrate is registered at the selected position on the support body by engaging the substrate in contact with the first registration member, which is arranged in the registering state in the first registering position.

An inkjet printer, an image forming method and an image quality compensation method thereof compensate for an image quality deviation in the ink jet printer. The method includes forming a first image on a printing medium fed at a first position, shifting the printing medium having the first image in a transverse direction to a feeding direction of the printing medium; forming a second image on the printing medium fed at the shifted position, and detecting a real shift amount of the printing medium by scanning the first and second images.

The present invention provides an automatic sheet feeding apparatus comprising sheet supporting means (4) for supporting sheets, sheet supply means (1) for feeding out the sheet from the sheet supporting means, separation means (5) for separating the sheets one by one at the feeding of the sheet by means of the sheet supply means, by regulating one of front corners of the sheets supported by the sheet supporting means in a sheet feeding direction, and skew-feed correction means (10) for correcting the skew-feed of the sheet by applying a resisting force to the sheet fed by the sheet supply means.

Two rollers (44,55) with lobes for feeding a sheet are disposed below the plane feed surface (22). The two rollers are rotatable on axes perpendicular to one another and move the sheet or the document to be printed in a direction perpendicular and parallel, respectively, to the printing direction (20) of the head (14) to align the sheet against inverted V elements (80) movable parallel to the printing direction, and against lateral guide (158) perpendicular to the printing direction. Suitable optical sensors (155,156) detect possible misalignment of the sheet and cause further rotation of the rollers to complete the alignment of the sheet against the guides. A testing device (108-120) detects the thickness of the document for positioning the head at a prefixed distance from the printing surface of the document itself.
摘要:
Disclosed is an inspecting chart including a reference pattern containing a first line segment group and a second line segment group, a first-side deviation pattern, and a second-side deviation pattern. The first line segment group is formed by a plurality of first line segments printed by a reference printing head at a first given interval. The second line segment is formed by second line segments printed by a printing head on a center between two adjacent first line segments or a center of each of the first line segments, the printing head being spaced away from the reference printing head in a the transportation direction of a print medium. The first-side deviation pattern and the second-side deviation pattern are printed with various deviations.
