The present disclosure relates to a marking method and device, and a repair system for a display panel in the field of display panel detection. The marking device includes: magnifying component and a marking component. The magnifying component is configured to magnify a target position point on a target object, and the marking component is configured to mark the target position point on the target object in accordance with the magnified target position point. The present disclosure may solve the problem that the operation process of marking the defective position point is complicated and simplify the operation process of marking the defective position point. The present disclosure may mark the defects of the display panel.

Apparatus, methods, and systems for dynamically modulating radiation energy in a printing system are disclosed. A system receives data comprising an image pattern for depositing ink on a substrate. The system determines one or more ink properties for the ink configured to be deposited onto the substrate. The ink properties and/or a color of the substrate are used to determine a corresponding energy level value for a radiation lamp. The ink is deposited in the image pattern on the substrate. One or more radiation lamps heat the substrate and the ink, wherein the radiation lamps are configured with the corresponding energy level values.

An image forming apparatus includes image forming units forming images, a movable body moving along a path extending in a direction in which the image forming units are arranged while the images are sequentially formed on the movable body or on a recording material transported by the movable body so as to be superposed with one another, a contact and separation unit moving to a contact position at which the contact and separation unit is in contact with the movable body and to a separation position at which the contact and separation unit is separated from the movable body and changing a load applied to the moving movable body as a position of the contact and separation unit is changed, and a change unit changing the load in a manner opposite to a change in the load upon a change in the position of the contact and separation unit.

A liquid discharge apparatus includes multiple liquid discharge heads, a medium mover, and circuitry. The multiple liquid discharge heads include a first liquid discharge head to discharge a treatment liquid onto a region of the medium and a second liquid discharge head to discharge a color liquid onto the region to paint the region, on which the treatment liquid is applied, in a predetermined color. The circuitry causes the first and second liquid discharge heads to form an evaluation chart. The evaluation chart includes patterns different in a combination of a first discharge amount of the treatment liquid and a second discharge amount of the color liquid. Further, the circuitry performs a setting of the first discharge amount with respect to the second discharge amount according to the coloring, and causes the second liquid discharge head to discharge the treatment liquid onto the region based on the setting.

Printers and other machines providing tangible outputs are provided. In one implementation, a printer comprises a housing having a fixed structure and a movable cover configured to be movable with respect to the fixed structure. The printer also includes a printing mechanism that is disposed inside the housing and is configured to print an image on a medium. The movable cover is movably attached to the fixed structure via a first pivoting mechanism that defines a first pivoting axis. The movable cover is configured to be pivoted about the first pivoting axis of the first pivoting mechanism. Also, the movable cover comprises a plurality of linked slats, each pair of adjacent linked slats being linked together by a second pivoting mechanism. Each second pivoting mechanism includes characteristics enabling a user to detach the adjacent linked slats from each other.
