摘要： The driving signal generation section is able to generate a first ejection drive pulse for ejecting the first liquid and a second ejection drive pulse for ejecting the second liquid. The control section forms a pre-dot group in advance on a landing target area of the first liquid in the ejection target by ejecting the second liquid on the basis of the second ejection drive pulse, and subsequently forms a pattern dot on the landing target area, on which the pre-dot group is formed, by ejecting the first liquid on the basis of the first ejection drive pulse. In the apparatus, a total length of the pre-dot group in a direction of the relative movement is longer than a total length of the pattern dot in the direction of the relative movement.

摘要： In an ink jet recording apparatus and method recording is performed by using a replaceable ink cartridge mounted in the ink jet recording apparatus, and includes a recording head for delivering ink therefrom. Cleaning of the recording head is carried out by sucking ink from the recording head. A cartridge absence time period is detected over which continues a cartridge-unmounted state of the ink jet recording apparatus in which the ink cartridge is removed from the ink jet recording apparatus. An amount of ink to be sucked for the cleaning is set, based on the cartridge absence time period, when the ink cartridge is mounted in the ink jet recording apparatus.

摘要： A timing signal generator generates an ejection timing signal each time a printing paper travels a predetermined distance relative to a head, and a driving signal generator inputs a driving signal based on writing data to the head each time an ejection timing signal is generated. In the course of printing, when an interval between two continuous ejection timing signals is equal to or longer than twice a basic time period of input of driving signal which is fixed for a head, a non-ejection driving signal which is a driving signal indicating a non-ejecting operation is input to the head between two driving signals respectively associated the two continuous ejection timing signals. Accordingly, it is possible to reliably and properly perform ejection of ink based on writing data with a time period equal to or longer than the basic time period.

摘要： A liquid ejecting apparatus according to the invention includes a liquid ejecting head capable of ejecting liquid from nozzle openings provided in a nozzle-forming surface, a nozzle-forming-surface visual-inspection unit for enabling a visual inspection of the nozzle-forming surface, and a liquid receptacle for receiving liquid discharged as waste liquid from the nozzle openings in the liquid ejecting head. The liquid receptacle is movable between a receiving position, where the liquid receptacle is positioned adjacent to the nozzle-forming surface, and a non-receiving position, where the liquid receptacle is positioned away from the receiving position. The liquid receptacle covers the nozzle-forming-surface visual-inspection unit when the liquid receptacle is positioned at the receiving position. The nozzle-forming-surface visual-inspection unit allows the nozzle-forming surface to be visually inspected when the liquid receptacle is positioned at the non-receiving position.

摘要： There is provided a printing apparatus which is capable of increasing the printing speed by employing a multi-head structure while maintaining or enhancing print quality. The printing apparatus prints on a print medium by using N print heads, where N is an integer equal to or larger than 2, assuming that two axes orthogonal to each other on a two-dimensional rectangular coordinate system are set to an X axis and a Y axis, each of the print heads being capable of printing M dots in a direction along the Y axis simultaneously, where M is an integer equal to or larger than 3, and at the same capable of printing M dot lines each extending in a direction along the X axis, by relative scan on the print medium in the direction along the X axis, the M dot lines being arranged side by side in the direction along the Y axis. At least two print heads of the N print heads are arranged in a manner such that selected ones of the M dot lines that can be printed by one of the at least two print heads overlap selected ones of the M dot lines that can be printed by another of the at least two print heads.
