A printing apparatus includes a conveyance unit configured to convey a sheet in a conveyance direction, a print unit configured to perform printing on the sheet conveyed by the conveyance unit, a light receiving unit configured to receive light and make an output according to the received light, and a control unit configured to control borderless printing by the print unit, the borderless printing including extra-printing from a sheet edge to outside of the sheet. The control unit sets an extra-printing amount by which printing extends off the sheet edge after the light receiving unit makes the output according to the received light.

An adjusting method for a printing apparatus includes a head configured onto perform printing on a medium, a winding shaft configured to wind thereon the transported medium, a shaft adjustment mechanism configured to adjust a position of the winding shaft, and a notification part configured to provide a notification, the method including a printing step for printing a scale onto the medium, a transporting step for transporting the scale to the winding shaft, an image-capturing step for image-capturing the scale, which is transported to the winding shaft, at two different locations of the medium in a direction along an axis of the winding shaft, a notification step for providing to the notification part a notification about a result based on a captured image of the scale, and an adjustment step for adjusting a position of the winding shaft in accordance with a result notified to the notification part.

A printing apparatus acquires characteristic information about a recording medium and executes a light quantity adjustment in a reading operation using a reading unit based on the acquired characteristic information. By using the above-described configuration, it is possible to prevent an increase in the number of processes for analyzing read data obtained by reading a test pattern.

A method for printing an image on a substrate is provided. The method includes: providing image template data; analyzing the image template data by identifying image components; printing the image using the image template data using a printing procedure based on printing parameters with a printer operating using printer configuration parameters; capturing the printed image; providing captured image data of the captured image; analyzing the captured image data. The analyzing including determining the region of interest within the captured image data based on definition parameters, identifying an image component and an image metric for the region of interest, relating the image metric to the image component, relating the identified image component to the identified image component of the region of interest, selecting parameters based on the image metric and/or the image component, and computing an actual correction parameter based on an optimization computing procedure using the image metric.

When a printing interruption cause occurs during printing of an image on a printing medium, printing of a page being printed is completed, and further only a position mark is printed on a printing resumption page. Then, a printing unit is stopped, and a conveyance speed is decelerated to stop conveyance of the printing medium. Next, the printing medium is rewound so that printing is resumed from the printing resumption page. Thereafter, the conveyance speed is accelerated to a predetermined speed, and printing is resumed from the printing resumption page on which the position mark is printed.

A measurement apparatus including: a conveyance unit configured to convey a sheet in a conveyance direction; a measurement portion configured to measure an image formed on the sheet; a first movement unit configured to move the measurement portion in a predetermined direction orthogonal to the conveyance direction; a second movement unit configured to move the measurement portion to a first position and a second position farther apart from the sheet than the first position; and a first abutment member, a second abutment member, a third abutment member, and a fourth abutment member, which abut against the sheet when the measurement portion is located at the first position. When the measurement portion is moved from the second position to the first position, the third abutment member and the fourth abutment member are brought into abutment against the sheet earlier than the first abutment member and the second abutment member.

A printing apparatus acquires characteristic information about a recording medium and executes a light quantity adjustment in a reading operation using a reading unit based on the acquired characteristic information. By using the above-described configuration, it is possible to prevent an increase in the number of processes for analyzing read data obtained by reading a test pattern.

A printing apparatus includes a casing, an optical sensor, a second light receiving portion and an adjustment part. The optical sensor includes a light emitting portion and a first light receiving portion. The optical sensor is provided at a position in the vicinity of the outlet and located within a conveying region. The conveying region is an area through which the print medium passes. The second light receiving portion is provided in the vicinity of the optical sensor and positioned outside the conveying region where external light is perceivable. The adjustment part is configured to adjust a sensitivity in the detection of the presence of the print medium by the first light receiving portion. Adjustment of the sensitivity of the first light receiving portion is performed based on an intensity of the external light received at the second light receiving portion.

A tablet printing apparatus 1 includes an inspection unit 53 determining whether or not the printed tablet T is good product, a good product collecting device 43 collecting the tablet T of the good product from the carrying belt 31a, a defective product collecting device 41 collecting the tablet other than the good product from the carrying belt 31a, a discharge confirming sensor 41c detecting whether or not the tablet other than the good tablet is collected by the defective product collecting device 41, and a re-inspection product collecting device 42 collecting the tablet T other than the good product from the carrying belt 31 a when a collecting operation for collecting the tablet T other than the good product is performed by the defective product collecting device 41, and the discharge confirming sensor 41c detects that the tablet T other than the good tablet is not collected.

An image forming apparatus includes a controller circuitry configured to control the ink-jet module to form a density adjustive image pattern on one of the multiple sheets, detect a jam during continuous feeding, and then determine whether or not images, which are to be formed on one or more fed-and-unejected sheets, include the density adjustive image pattern, where the images include the density adjustive image pattern, determine whether or not the unejected sheet, on which the density adjustive image pattern is to be formed, has passed through a certain position of the sheet conveyer path, and control the ink-jet module, where the unejected sheet, on which the density adjustive image pattern is to be formed, has passed through the certain position, not to re-form the density adjustive image pattern and to re-form images on rest of the unejected sheets.
