摘要： An image forming apparatus includes a head, a detector, and circuitry. The head forms an image on a recording medium. The detector detects a vertical movement of the recording medium and a distance to the recording medium in a vertical direction. The detector includes an optical sensor to project light to the recording medium and receive the light reflected from the recording medium. The circuitry sets a first area based on a result of detection performed by the detector. The first area is an area in which the recording medium and the head collide with each other. The circuitry retracts the head to prevent the recording medium and the head from colliding with each other, in a case where a position of the head is in the first area.

摘要： A printing device includes a head and a carriage. The head has a nozzle. The head is configured to eject liquid from the nozzle toward a printing medium. The carriage is configured to move the head in a first direction. The carriage includes a first distance sensor. The first distance sensor is configured to measure a distance between the head and the printing medium. The first distance sensor is a specular reflection type distance sensor. The first distance sensor includes a light-emitting element and a light-receiving element. The light-emitting element and the light-receiving element are aligned in the first direction.

摘要： A three-dimensional object printing apparatus includes a liquid discharge head having a nozzle surface provided with a nozzle array including a plurality of nozzles for discharging a liquid, a moving mechanism that changes a position of the liquid discharge head with respect to a three-dimensional workpiece, and a sensor that detects a positional relationship of the liquid discharge head with respect to the workpiece, in which when an axis parallel to a normal line of the nozzle surface is set as a first axis, an axis parallel to the nozzle surface and intersecting an extending direction of the nozzle array is set as a second axis, and an axis that intersects both the first axis and the second axis is set as a third axis, the sensor detects a relative positional relationship of the liquid discharge head with respect to the workpiece in a direction along the third axis.

摘要： An apparatus with an ink printing device generates imprints on items moving in a transport direction. The ink printing device displaces the ink cartridge, which is a single inkjet print head of at least 1 inch in width transverse to the transport direction, as well as in a vertical direction, and counter to the vertical direction. A movement mechanism of the printing module is provided to vertically raise and lower the inkjet print head. The movement mechanism has a mechanism for motorized movement of the inkjet print head, and a mechanism for manual displacement in the vertical direction.

摘要： A printer attenuates banding visual defects arising from a lack of flatness in media as ink is ejected onto the media. The printer includes a detector that generates a signal corresponding to the slope in the media and a controller that modulates a volume of the ink drops ejected by one or more printheads in the vicinity of the slope in the media.
