摘要： A liquid detection method and a liquid discharging device to detect whether or not a liquid can be supplied in a state in which a liquid channel from a tank for accommodating the liquid to each discharging port of a recording head is not disconnected by a bubble. A detection-signal input terminal is provided at a position where it contacts the liquid. A detection terminal is provided at a position where it does not electrically contact the liquid and is isolated from the liquid within the tank via a lower wall of the tank, made of an insulating plastic material, and the air. An electrical signal is input from a recording apparatus to the detection-signal input terminal via a connection terminal. The input electrical signal is transmitted through the ink within the recording head, the liquid channel within a joint, and the liquid within the tank. The detection terminal, comprising a conductive metal plate provided at a position corresponding to the entire lower surface of the tank, detects the waveform of a voltage. By comparing the detected voltage with a predetermined threshold, it is determined whether or not the liquid can be normally supplied.

摘要： Provided is a print position control method whereby displacement of a print position in a wide range can be corrected very accurately, without reducing a printing speed or increasing a manufacturing cost. Thus, a printing apparatus includes: a first correction unit, for correcting a print position at accuracy equal to the resolution of the printing apparatus; and a second correction unit, for correcting the print position at accuracy higher than the resolution and in the range of an area that corresponds to one pixel of the resolution. With this arrangement, the print position displacement in a wide range equal to or greater than one pixel can be corrected by the first correction unit, and a print position displacement smaller than one pixel can be corrected by the second correction unit. Therefore, correction of a print position displacement in a wide range is enabled at a higher accuracy.

摘要： In a printing apparatus which performs printing by scanning a printhead having printing elements arrayed in a predetermined direction on a printing medium in a direction crossing to the array direction on the basis of information transmitted from a host apparatus, stores print data transmitted from the host apparatus, and has a buffer smaller in capacity than a print data amount printed on the printing medium by one scanning of the printhead, the buffer is divided into a plurality of blocks corresponding to rectangular regions printed by scanning. The use order of the blocks is so managed as to circularly store print data in the blocks along with the progress of printing. When print data representing non-driving of the printing elements successively exist in a predetermined amount, the predetermined amount of print data is represented by specific control data without storing the predetermined amount of print data in the blocks. High-speed, high-quality printing can be achieved with a low-cost arrangement having a memory smaller in capacity than a data amount printed by one main scanning.

摘要： Image deterioration is suppressed as much as possible which is complexly generated by variations of printing positions respectively of printing elements in a printing element row and by displacement of printing positions among printing element rows. To this end, a first adjustment value for adjusting printing positions among a plurality of printing elements included in a printing element row is obtained. Next, printing positions among a plurality of printing elements are adjusted based on the first adjustment value. Then a second adjustment value for adjusting printing positions among not less than two of the printing element rows is obtained. Thereby variations of printing positions in a discharge port row and displacement of printing positions among discharge port rows are properly adjusted in different phases, and adverse effects generated by two kinds of different causes are collectively suppressed.

摘要： A recording device drives a recording head mounted on a carriage while main-scanning by moving the carriage in a direction generally orthogonal to the sheet-feeding direction of a sheet. The recording device drives a first nozzle of the recording head at an upstream side in the sheet-feeding direction of the sheet to form a first dot pattern while scanning the carriage and drives a second nozzle at a downstream side in the sheet-feeding direction of the sheet to form a second dot pattern. The recording device feeds a region where the first dot pattern is recorded to a position facing the second nozzle. The second dot pattern is recorded in a region where the first dot pattern is not recorded.
