An inkjet printer including an inkjet head, a head scanning unit, a wave shape generating mechanism to deform a recording medium into a predetermined wave shape, an obtaining device to obtain information concerning a type of the recording medium to be used in a printing operation, a gap information storing device to store gap information related to a gap between an ink discharging surface and the recording medium in association with a predetermined type of the recording medium, the gap information being acquired from a predetermined range in the recording medium, and a correcting device to correct the gap information according to the type of the recording medium obtained by the obtaining device when the type of the recording medium obtained by the obtaining device is different from the predetermined type of the recording medium stored in association with the gap information, is provided.

A printing apparatus, a printing method, and a control apparatus are provided that are capable of reliably preventing a printing unit from colliding, when a first press member or a second press member is displaced, with a displaced press member, and then allowing the printing unit to quickly restart a printing operation. A printing apparatus includes a transport unit configured to transport a work as a recording medium, a printing unit configured to perform printing on the work while moving in a width direction of the work, a first press member configured to press one side of the work in the width direction, a second press member configured to press another side of the work in the width direction, and a detecting unit configured to detect each of a displacement of the first press member in a vertical direction.

A method is provided that is implemented on a control device connected with an inkjet printer, which includes an inkjet head having an ink discharging surface, a head scanning unit reciprocating the inkjet head relative to a recording sheet along a scanning direction parallel to the ink discharging surface, and a wave shape generating mechanism deforming the recording sheet in a predetermined wave shape that has tops of portions protruding in a first direction toward the ink discharging surface and bottoms of portions recessed in a second direction opposite to the first direction alternately arranged along the scanning direction, the method including acquiring gap information related to a gap between the ink discharging surface and each individual one of the tops and the bottoms on the recording sheet, and determining whether the gap information acquired for each individual one of the tops and the bottoms is abnormal.

The printing device comprises: a print head for printing on a tape; a platen roller for conveying the tape by rotation with the tape held between the print head and the platen roller; a supporter for rotatably supporting the platen roller; and a cam including a first guide for releasing pressing of the platen roller against the print head and a second guide for pressing the platen roller against the print head.

A medium supporting mechanism includes a medium supporting unit and a medium holding unit. The medium supporting unit includes a support face that supports a medium, a guide rail intersecting a transport direction in which the medium is transported, and an engaged portion positioned upstream of the first guide rail. The medium holding unit includes a holding portion that covers an edge of the medium in a width direction, an abutting portion movable between an abutting position and a separation position, a switching portion that switches a position of the abutting portion between the abutting position and the separation position, and an engaging portion engageable with the second guide rail. The medium holding unit includes a pressing portion downstream of the abutting portion in the transport direction. The pressing portion presses the support face to move a position of the holding portion in a direction away from the support face.

An apparatus can control the movement of a substrate through a manufacturing process. The apparatus can transport the substrate in the machine direction of the manufacturing process and can control the movement of the substrate in the cross-machine direction as well as the z-direction.

When a wave shape is formed in a sheet of paper, a suppression of a reduction in recording quality that is caused by a shape of the paper is achieved, and thus, favorable recording quality is obtained.

In an example, an edge holder may include a strap, a first end cap fixed to the strap, and a second end cap fixed to an opposite end of the strap from the first end cap. The second end cap may include a fixed end and a cam engaged with the fixed end. The cam may adjustably tension the strap between the first end cap and the second end cap.

A second inkjet head, a second platen, and a second pair of conveyance rollers configured to convey a sheet toward the second platen downward with respect to a horizontal direction are arranged at lower positions than a first inkjet head arranged upstream of the second inkjet head, a first platen arranged upstream of the second platen, a first pair of conveyance rollers arranged upstream of the second pair of conveyance rollers and configured to convey the sheet toward the first plates downward with respect to the horizontal direction, respectively.

An inkjet printer is provided that is configured to store a plurality of pieces of gap information respectively corresponding to a plurality of examined sections discretely arranged along a head moving direction on a recording sheet, each of the plurality of examined sections including a corresponding one portion of top portions and bottom portions on the recording sheet, and calculate interpolation gap information to be interpolated over a whole width in the head moving direction of at least one of a plurality of segments, each of which has a width in the head moving direction defined by two adjacent sections of the plurality of examined sections, based on the stored gap information.
