The object of the present invention is to propose a novel device and a novel method to allow the transportation of printable substrates precisely, suited to substrates of various types, sizes and thicknesses. Furthermore, the invention is suited to printing machines that involve no contact with the substrate, such as inkjet printing machines.

A medium transport device includes a medium transport path for transporting a medium, and a medium detection unit that detects a medium by using detection light intersecting the medium transport path. the medium detection unit is a part constituting an optical path of the detection light, and includes a first optical component positioned on a first side of the medium transport path, and a second optical component positioned on a second side with the medium transport path interposed therebetween, and the second optical component is accommodated in a recess formed in a wall face extending in a direction intersecting a path surface of the medium transport path.

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 medium transport apparatus includes a body portion, an inversion unit, and an extension unit. The body portion has a second manual feed path for a sheet material. The inversion unit is configured to be mounted on and separated from the body portion, covers the second manual feed path when the attachment/detachment portion is mounted the body portion, and exposes a portion of the second manual feed path when the attachment/detachment portion is separated from the body portion. The extension unit is configured to be attached to and detached from the attachment/detachment portion. The extension unit extends, in a state in which the inversion unit is separated, the second manual feed path in a transport direction of the sheet material by being detached from the inversion unit and attached to the body portion.

An inventive rubber composition contains a rubber component including EPDM, a peroxide crosslinking agent, a white filler, and not less than 0.1 part by mass of a quaternary ammonium salt based on 100 parts by mass of the rubber component. An inventive molded rubber product (1) is made from the rubber composition. Thus, the novel rubber composition containing the rubber component including the EPDM, the peroxide crosslinking agent and the white filler can be imparted with any desired color (e.g., a light color such as white or a non-black color) and can form a molded rubber product excellent in strain resistance properties and the like without inhibition of the crosslinking of the EPDM. The molded rubber product is produced by using the rubber composition.

Systems and methods for adjustable S-rollers in a print system. One system is an apparatus that includes a pair of rollers configured to be positioned on opposite sides of a web of continuous-forms print media, and a coupling member that connects the pair of rollers, wherein the coupling member pivots about a common axis between the pair of rollers. The apparatus also includes a drive unit configured to pivot the coupling member and a controller to receive input that describes at least one property of the web, and to direct the drive unit to pivot the coupling member to a position that applies a normal force between the web and at least one of the pair of rollers based on the at least one property of the web.

A printer is disclosed. The printer has a media control system to control the tension in media loaded in a paper path in the printer. A motor in the media control system is characterized to determine a plurality of motor characteristics. The media control system uses the motor characteristics to adjust the control signal to the motor.

A meandering correction apparatus includes a transport mechanism, an orientation measurement part, a Young's modulus calculation part, a meandering prediction part and a meandering correction part. The transport mechanism transports an elongated strip-shaped base material in a longitudinal direction thereof along a transport path. The orientation measurement part measures fiber orientations of the base material in respective measurement regions on the transport path, the measurement regions being different in widthwise position from each other. The Young's modulus calculation part calculates Young's moduli of the base material for the respective measurement regions, based on the fiber orientations. The meandering prediction part predicts subsequent meandering of the base material, based on the Young's moduli, to output meandering prediction information. The meandering correction part corrects the widthwise position of the base material, based on the meandering prediction information. The meandering correction is made based on the fiber orientations of the base material. Thus, the widthwise position of the base material is corrected without depending on only edge sensors.

A medium supplying apparatus with a detachable rolled medium is provided. In the medium supplying apparatus, the rolled medium is fed to a far side of a setting-and-removing direction of the rolled medium. The medium supplying apparatus includes a plurality of guide members configured to guide the rolled medium when the rolled medium is set. The guide members include at least one contact member which at least partially contacts only a lower outer periphery of the rolled medium and at least one auxiliary member which does not contact the outer periphery of the rolled medium. The contact member and the auxiliary member are connected at a base via the same rotary shaft. The auxiliary member is shorter than the contact member in a medium feeding direction, and is disposed in parallel with the contact member.

A device, method and system for receiving and submitting a substrate, the device including an XY table, the XY table having one or a plurality of sides for accepting a substrate, a set of manipulators coupled to the XY table, the manipulators configured to accept and register the substrate from the one or plurality of sides of the XY table, and a set of retractable dividers on the XY table configurable to register one or a plurality of substrates concurrently.
