Disclosed is a workpiece processing apparatus that performs a predetermined processing on a workpiece. The workpiece processing apparatus includes: a workpiece table configured to place the workpiece thereon; a processor configured to process the workpiece placed on the workpiece table; a movement mechanism configured to relatively move the workpiece table and the processor; a position measuring device configured to measure a position of the movement mechanism; a detector configured to detect a position of the workpiece placed on the workpiece table; and a corrector configured to calculate a positional correction amount of the workpiece table based on a measurement result of the position measuring device and a detection result of the detector.

Certain examples of apparatus for applying fluid in a printing system are described. The apparatus comprise a first chamber having a first aperture extending along a first axis, and a second chamber having a second aperture extending along a second axis, wherein the first axis is substantially parallel to the second axis. The second chamber is movable with respect to the first chamber. Also, methods for supplying a fluid, and printing systems are described.

A recording apparatus includes: a housing; a recording section that performs a recording operation on a medium and is disposed inside the housing; a storage section that stores the medium; a transport route along which the medium is transported; a transport section that transports the medium; a reading section that reads an original sheet and is positioned higher than the recording section; a supply section that supplies the original sheet to the reading section; and a supply route through which the original sheet passes. Each of the supply and transport routes is formed at substantially right angles to a width of the housing. The transport route has a curved section in which the medium is turned over. The reading section is positioned behind the recording section in a depth direction from the front to rear surface of the housing.

A single pass inkjet printer that utilizes a modular printing system with one or more self-contained printing modules, where each printing module is easy to remove and replace from a large printing machine, thus resulting in an overall system that is easy to service and maintain. Each module is a self-contained printer including an ink supply, printhead drive electronics, and printhead assembly in order to provide one color or fluid of inkjet printing capability. Each module includes a precise three-point compliant self-aligning mount system to obtain accurate printhead positioning, and a unique integrated printhead tending system that includes a compact movable vacuum knife for cleaning the printheads, and a printhead capping station for sealing and protecting the printheads from the ambient environment when not in use.

Disclosed are a method for preheating a substrate treating apparatus capable of shortening a preheating time and simultaneously performing a maintenance operation, and a computer program for the same. The method includes setting a parameter related to preheating of a preheating target component among components constituting the substrate treating apparatus; and preheating the preheating target component based on the set parameter, wherein a movement range of the preheating target component is limited to a value within a movable range.

A liquid ejection apparatus is provided that includes a plurality of liquid ejection head units that are configured to eject liquid onto a conveyed object being conveyed; a detection unit that is provided with respect to each liquid ejection head unit of the plurality of liquid ejection head units and is configured to output a detection result indicating at least one of a position, a moving speed, and an amount of movement of the conveyed object with respect to a conveying direction of the conveyed object; and a control unit configured to control each liquid ejection head unit among the plurality of liquid ejection head units to eject liquid at a timing based on a plurality of the detection results of a plurality of the detection units.

A device actuation system for actuating a treatment device includes a first drive gear rotatably mountable to the treatment device, a coupler rail slidably mountable to the treatment device, a second drive gear rotatably mountable to the coupler rail, and a coupler gear rotatably mountable to the treatment device and engageable with the coupler rail. In addition, the device actuation system includes a drive rail locatable between the first drive gear and the second drive gear of the gear system. The coupler gear is rotatable to move the coupler rail in a manner maintaining the second drive gear in continuous engagement with the drive rail against the first drive gear. The first drive gear and the second drive gear are rotatable in a manner causing at least one of translation and rotation of the treatment device relative to the drive rail.

A printing apparatus comprises a carriage including a print head that discharges ink, the carriage reciprocally moving relative to a print medium, a wiping unit configured to wipe a discharge port surface, and a control unit configured to control a movement operation of the carriage and a wiping operation of the wiping unit such that when a deceleration when stopping the carriage is a first deceleration, a time from when the carriage stops to when the wiping unit starts wiping is set to a first time, and when the deceleration when stopping the carriage is a second deceleration lower than the first deceleration, the time from when the carriage stops to when the wiping unit starts wiping is set to a second time shorter than the first time.

A print device includes a head unit holding a heat sink, a head holding member holding the head unit, a platen roller, a support shaft supporting the head holding member to pivot between a close position and a separated position, an urging member, and an adjustment mechanism including an adjustment shaft and an eccentric cam. The separated position is a position where the print head is separated from the platen roller than the close position. The urging member urges the head unit and applies a pressing load pressing the print head against the platen roller. The eccentric cam rotates around the adjustment shaft and coming into contact with the head holding member in a state of being offset with respect to the adjustment shaft. The adjustment mechanism adjusts a position of heating elements of the heat sink with respect to the platen roller by rotating of the eccentric cam.

An inkjet recording device has a head base, a head unit, and an adjustment mechanism. The adjustment mechanism has a guide screw, a moving member, the operation member for rotating the moving member, and an adjusting member. The moving member has a shaft hole screwed into the guide screw, and moves in an axial direction of the guide screw by rotating with respect to the guide screw. The adjusting member has a first contact portion in contact with the moving member and a second contact portion in contact with the head unit. The second contact portion moves in a direction toward the head unit and a direction away from the head unit, by moving the moving member in contact with the first contact portion in the axial direction of the guide screw.
