It is intended to allow whether or not a noise included in a read image is a noise due to an ink ejection failure to be more reliably determined. An image reading device includes an image reading unit that reads an image formation surface of paper by using a reducing optical system and a control unit. The image reading unit includes a plurality of read sensors disposed at positions displaced from each other in a main scanning direction. The plurality of read sensors are disposed to be able to read the image formation surface by using at least a local region of the image formation surface as a common region to be read. The control unit determines, based on a first image obtained by a first read sensor included in the plurality of read sensors and on a second image obtained by a second read sensor included in the plurality of read sensors, an amount of displacement of a noise resulting from a parallax between the first read sensor and the second read sensor and determines, based on the amount of displacement, whether or not the noise is present on the image formation surface.

INKJET RECORDING APPARATUS
20230311497 · 2023-10-05 · ·

An inkjet recording apparatus includes a conveyance belt, a recording head, a control portion, an interval detection sensor, a thickness detection reference member, and a storage portion. The control portion is capable of executing an interval detection mode, a thickness calculation mode, and a landing timing correction mode. In the landing timing correction mode, the control portion sets the landing timing to be equal to a reference landing timing when the thickness of the conveyance belt stored in the storage portion is equal to a predetermined reference thickness, sets the landing timing to be earlier than the reference landing timing when the thickness of the conveyance belt stored in the storage portion is larger than the reference thickness, and sets the landing timing to be later than the reference landing timing when the thickness of the conveyance belt stored in the storage portion is smaller than the reference thickness.

SYSTEMS AND METHODS FOR HANDLING A FLEXIBLE WEB

According to one aspect, a web handling system comprises a plurality of cross-grooved idler rollers, an imaging drum, a nip roller adjacent the imaging drum and forming a nip therewith, and a spreader roller disposed between the plurality of idler rollers and the nip roller. Each idler roller is disposed no more than a first distance from an adjacent idler roller, spreader roller, and nip roller and the spreader roller is disposed no more than a second distance from the nip. The first distance is in a range of 38 to 28 inches, 36 to 30 inches, or 35 to 33 inches and the second distance is in a range of 6 to 11 inches, 6.5 to 9 inches, or 7.0 to 8.5 inches.

Inkjet printing apparatus and printing method with conveying print medium in first direction and second direction and with control of nip of conveyance rollers

An object is to provide a full-line inkjet printing apparatus and a printing method that can suppress occurrence of image degradation in the case where a conveyance roller conveys a print medium and multipass printing is performed. The maximum conveyance amount in a return route is set to be smaller than a distance between the conveyance roller and a print head.

RECONFIGURABLE SUPPORT PADS FOR FABRIC IMAGE TRANSFERS
20230364926 · 2023-11-16 ·

The techniques described herein relate generally to reconfigurable support pads for fabric image transfers. Specifically, according to one or more embodiments of the present disclosure, reconfigurable support pads are provided for fabric image transfers (e.g., silk screening, heat transfer, direct-to-garment printing, etc.). In particular, the techniques herein provide for various adjustable configurations of portions of the fabric substrate support, which may be changed for different thicknesses of garments, and more particularly, that allow for varied thicknesses found on the same garment. For example, by configuring the support in a first “flat” configuration, a plain tee shirt may lay flat, and then configuring the support in a second “two-tiered” configuration, with one portion lower (or higher) than the other, allows for a hoodie with a thicker pocket portion at the “belly” of the garment to also lay flat. Other configurations are also available, whether manually adjusted or else dynamically controlled (e.g., using actuators) based on the type of garment selected on an associated control system.

Document Imaging System and Method for Imaging Documents
