The substrate treating apparatus provided includes a stage extending in a first direction, for moving a substrate in the first direction, and having an air floating system, a gantry arranged on the stage to extend in a second direction crossing the first direction, a head module installed on the gantry and movable in the second direction, and a displacement sensor installed in the head module, for measuring a separation distance between the substrate and stage, wherein at a first position, the head module ejects ink to the substrate and the displacement sensor measures a first separation distance between the substrate and the stage, and at a second position that is different from the first position, the head module ejects ink to the substrate and the displacement sensor measures a second separation distance between the substrate and the stage.

A waveform determination method is disclosed that includes acquiring second timing information regarding a timing at which the flight distance of the droplet reaches the first distance when each of the plurality of waveform candidates indicated by the second waveform information is used, and a determination step of determining a waveform of each of the first drive pulse and the second drive pulse based on the first timing information and the second timing information.

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.

An inkjet printer is provided, which is configured to acquire gap information related to a gap between an ink discharging surface and a recording sheet in each individual position of top-formed positions and bottom-formed positions within a predetermined wave-shape generating range, identify, when the predetermined wave-shape generating range includes a partial range in which the recording sheet is not placed, a top-formed position where the gap information has not been acquired and a bottom-formed position where the gap information has not been acquired, within the partial range, complement the unacquired gap information in the identified top-formed position with a value determined based on the respective pieces of gap information acquired in other top-formed positions, and complement the unacquired gap information in the identified bottom-formed position with a value determined based on the respective pieces of gap information acquired in other bottom-formed positions.

A method of depositing printing fluid on a sheet of corrugated media comprises determining a deformation of a sheet of corrugated media, adjusting control parameters for a plurality of nozzles based on the determined deformation, and depositing printing fluid from the plurality of nozzles onto the sheet of corrugated media according to the adjusted control parameters.

An ink jet printing apparatus includes: a conveying mechanism that moves at least one of a print medium and an ink jet head in a predetermined conveyance direction; a height information detecting unit that obtains information related to the height of the surface of the print medium; a moving mechanism that moves at least one of the ink jet head and the print medium upward and downward in the vertical direction; and a control unit that controls the ink jet head while sequentially controlling the moving mechanism accompanying conveyance by the conveying mechanism, based on the information related to the height which is detected by the height information detecting unit, thereby maintaining the distance between the print medium and the ink jet head to be within a range which is set in advance, to perform a printing process on the print medium.
