Formation of a plurality of wear visibility grooves 10 has been focused. An elastic roller includes: an inner layer side elastic material 4; a coating layer 5 disposed on an outer periphery of the inner layer side elastic material 4, the coating layer configured to make contact with the belt-shaped member; and a plurality of wear visibility grooves 10 (11, 12, 13) formed on an inner side of the coating layer 5 and formed on a surface of the inner layer side elastic material 4 in a circumferential direction, the plurality of wear visibility grooves being successively formed in an axial direction of the roller shaft, wherein at least two grooves of the plurality of wear visibility grooves have different heights, and filler is filled in the plurality of wear visibility grooves 10, the filler having a color different from that of the inner layer side elastic material 4 and different from that of the coating layer 5, and material of the filler is the same as that of the coating layer 5.

A printer includes a supporting table to support a recording medium, a recording head located above the supporting table to eject ink toward the supporting table, a first contact detector located above the supporting table and lower than the recording head, an oscillator to vibrate the first contact detector, and a vibration detector to detect vibration of the first contact detector and transmit a signal corresponding to the detected vibration. The printer stores a threshold related to the vibration of the first contact detector and determines that an object has come into contact with the first contact detector when an amount of the vibration detected by the vibration detector is equal to the threshold or less.

A booklet processing mechanism is described that includes a spine guidance system that is configured to hold the area adjacent to the spine of an opened, multiple sheet booklet against a backing plate during processing on a page of the booklet, for example by a laser or during vision verification. The spine guidance system is configured so that it resides closely adjacent to the spine of the booklet, below the field of lasing by the laser or other processing operation, so that it does not interfere with the processing operation.

A method for adjusting a printing apparatus, which the printing apparatus includes: a platen for supporting the medium, an imaging unit, a winding shaft for winding the medium, a shaft adjusting mechanism configured to adjust the position of the winding shaft, and a notifying unit configured to perform notification, comprising: a jig installing step for attaching one end of a strip-shaped jig, on which graduations are formed, to the winding shaft, and locking the jig to the platen, along a transporting path at both ends in a width direction of the medium, an imaging step for imaging the graduations by the imaging unit at two locations different from each other, in a direction orthogonal to a transport direction of the medium on the platen, a notifying step for notifying a result based on an image imaged by the imaging unit, and an adjusting step for adjusting the shaft adjusting mechanism.

A process for printing multiple layers on a fabric or other material using UV-curable ink that includes a step of printing a first layer on the material and another step of partially curing the first layer. A next step includes printing a partially UV-transparent layer over the first layer and fully curing the UV-transparent layer while simultaneously fully curing the first layer.

A substrate unloading system comprising a gripper mounted on a slanted plane and movable along the slanted plane, and a platen onto which the substrate is attached, the platen configured to be moved down in a vertical direction and away from the gripper in a horizontal direction, the gripper and the platen configured to move simultaneously so that the substrate remains substantially horizontal.

A processor of a printer conveys a platen relative to a head in a conveyance direction, toward a printing position. The printing position is a position at which a nozzle surface of the head faces the platen in a discharge direction. The printer is provided with a first sensor. The first sensor detects a print medium positioned at a first detection position. The first detection position is a position separated from the nozzle surface in the discharge direction. When the print medium is detected by the first sensor after a start of conveyance of the platen, the processor moves the platen relative to the nozzle surface and separates the platen from the nozzle surface in the discharge direction. After that, the processor conveys the platen relative to the head in the conveyance direction, toward the printing position.
