Abstract: An apparatus for adjusting a head gap between printing paper and a nozzle of a printing head in an inkjet printer includes a carrier mounted with the printing head, a chassis having a carrier shaft guiding a movement of the carrier, an eccentric cam formed on one end of the carrier shaft, a carrier driving part moving the carrier right and left along the carrier shaft, and a paper-transporting roller driving part driving a paper-transporting roller of transporting printing paper to be printed. The apparatus includes a carrier ascent/descent part ascending and descending the carrier by rotating the carrier shaft, and a clutch device selectively transmitting a driving force of the paper-transporting roller driving part to the carrier shaft to rotate the carrier shaft and disposed to be actuated by the carrier which is moved by the carrier driving part when the head gap should be adjusted. Accordingly, the apparatus can automatically adjust the head gap by using only the driving force of the carrier driving part and the paper-transporting roller driving part without using a separate driving motor.

Abstract: An apparatus for leaving space between paper and a head of an ink-jet printer includes a plurality of paper insertion angle change ribs located in front of a paper guide for controlling the paper raised. The paper guide is mounted at the front side of a deflector guide of the head. Therefore, the angle of the paper inserted to the head is changed, as the place where the paper curls up is changed. As a result, maximum space between the paper and the head is attained. The head is not contacted with the paper, and thus is not stained with ink on the paper so that there is the improvement of reliability of products.

Abstract: In a printing apparatus having a plurality of full-line print heads each having a print element array corresponding to the width of a print medium, upon receiving print data that uses a plurality of print media, a print duty, which is the ratio of the number of nozzles used in a print process to the total number of nozzles, is computed as a numerical value that pertains to electric power to be supplied to the print heads upon printing that print data. When the computed value is larger than a predetermined value that represents electric power which can be supplied from a power supply of the printing apparatus, the distance between the plurality of print media is increased so that the numerical value that pertains to the electric power becomes equal to or smaller than the predetermined value. With this control, deterioration of image quality and extreme drop of the printing speed can be prevented without unwantedly increasing the power supply capacity.

Abstract: The present invention resides in an apparatus (8) and method for maintaining a print head (10) at a substantially constant, closely spaced working distance (22) from a surface (17) of a printing receiver (16) during relative translational movement between the print head (10) and the receiver (16) along a predetermined path of movement for depositing liquid or ink droplets (12) onto the surface (17), the apparatus (8) including an actuator (20) connected to the print head (10) and controllably actuable for moving the print head (10) toward and away from the receiver (16), an element (35,36) for detecting a representative distance between the print head (10) and locations on the surface (17) of the receiver (16) along the path of movement and generating a signal having a value representative of or related to the representative distance, an element (46) for comparing the signal value to a reference; value representative of the working distance (22) for determining a difference between the signal value and the reference value and generating a control signal representative of the difference, and a control element (24) for receiving the control signal and responsively controllably actuating the actuator (20) to move the print head (10) toward or away from the receiver (16) to locate the print head (10) at the working distance (22) from the locations on the surface (17) of the receiver (16) when the print head (10) is positioned for depositing the liquid or ink droplets thereon. The method of the present invention includes the steps of (a) generating signals representative of distances between the print head (10) and the locations on the surface (17) of the receiver (16) along the path of movement prior to the print head (10) being positioned for depositing liquid or ink droplets onto the locations on the surface (17), respectively; and (b) responsively to the signals, as required, moving the print head (10) toward or away from the receiver (16) to locate the print head (10) at substantially the closely spaced working distance (22) from the locations on the surface (17) of the receiver (16) when positioned for depositing the liquid or ink droplets thereon, respectively.

Abstract: The spacing between the printhead of an inkjet printer cartridge and the print medium is dynamically controlled by an apparatus that slightly rotates the carriage that holds the cartridge. In one embodiment, the rotation is effected by actuation of a cam that resides between the rotatable carriage and a fixed part of the printer. The printhead-to-paper spacing is thus optimized for highest print quality.

Abstract: The recording apparatus and the recording method of the invention are provided with a recording head for ejecting ink onto a recording medium, a scanning section for moving the recording head in a predetermined direction to scan the recording medium and a correction section for controlling an ejection timing of the ink according to a discrepancy information on the recording medium to correct landing positions of the ink droplet on the recording medium. The discrepancy information on the recording medium represents a deviation of a paper-nozzle distance from a reference value. The paper-nozzle distance represents a distance from a nozzle portion of the recording head to the opposing recording medium. The recording apparatus and the recording method of the invention can correct the droplet landing position on the surface of the paper in the scan direction and produce an image with little dot position deviation.
