A medium flattening method, when a medium is transported by being adhered to an adhesive layer which is on a surface of a transport belt, includes detecting a presence or absence of floating being generated in the medium on the transport belt using a sensor, executing a process for flattening to flatten the floating in the medium in the case where the floating exists, and transporting the medium, where the floating is eliminated using the process for the flattening, to a liquid discharge region of a liquid discharge section.

PRINT MEDIA EDGE REPAIR
20170341422 · 2017-11-30 ·

Examples described herein include a print media edge repair system that includes a first repair element disposed adjacent to a media handling path to repair a leading edge of a sheet of print media as the sheet of print media moves into a position relative to a printing system associated with the print media edge repair system. The print media repair system may also include a second repair element disposed opposite the first repair element across the media handling path to repair a trailing edge of the sheet of print media as the sheet of print media moves into the position relative to a printing system.

METHOD FOR CONTROLLING A WEB IN A PRINTING APPARATUS

A method is provided for controlling a web in a printing apparatus The printing apparatus includes a transport assembly for moving the web through a transport path along a printing unit for printing an image onto a print area of the web. The method includes feeding the web from a supply roll through the transport path to the transport assembly; and switching the printing apparatus to a ready-to-print mode, wherein the printing unit does not print an image on the web and the web is maintained ready to be printed on. In a printing mode after the ready-to print mode, the following steps are performed: moving the web through the transport path in a transport direction along the printing unit by the transport assembly; and printing the image onto the print area of the web by the printing unit. The image is printed by applying an image material, which solidifies on the web during the printing step. The ready-to-print mode includes the step of: operating the transport assembly to prevent a deformation of the print area of the web in the transport path, while maintaining the web in the ready-to-print mode. The web is maintained ready to print while preventing a deformation of the print area of the web in the transport path.

TRANSPORT DEVICE AND LIQUID EJECTING DEVICE
20230173831 · 2023-06-08 ·

A transport device includes a roller unit having a first roller, a second roller, and a third roller among which a medium supplied from a holding unit holding the medium is wound, a transport unit configured to transport the medium passing through the roller unit, and a support portion movably supporting the roller unit with respect to the transport unit.

LIQUID EJECTION APPARATUS

A liquid ejection apparatus includes a medium container, a liquid ejection head, a mover, and a controller. The mover is configured to execute, among a first moving operation of moving a sheet-like medium and a second moving operation of moving the liquid ejection head, at least the first moving operation. The controller causes the liquid ejection head and the mover to alternately or simultaneously perform execution of the first moving operation and execution of ejection and second moving operations, and adjusts at least one selected from the group of an amount of liquid to be ejected, a time interval between the ejection operations when alternately performing execution of the first moving operation and execution of the ejection and second moving operations, and a moving speed of the medium when simultaneously executing the ejection operation and the first moving operation, according to medium information relating to curling of the medium.

PRINTING APPARATUS
