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： There are provided a waste ink reservoir and an ink jet printer incorporating the waste ink reservoir. A waste ink absorber has a top surface, for receiving waste ink from the print head at the top surface, and then absorbing the waste ink for storage therein. The waste ink absorber has a plurality of ink absorbent boards arranged in a vertically layered structure and formed with respective through holes vertically extending therethrough, such that adjacent through holes of absorbent boards at each pair of respective adjacent layers are displaced from each other, thereby allowing the adjacent through holes to partially communicate with each other. A waste ink container accommodates the waste ink absorber.

摘要： An ink jet recording apparatus and a method of flushing a recording head of the same are provided. A recording medium is fed along a predetermined feeding passage in a predetermined feeding direction. An ink jet recording head is arranged in a manner movable along a with of the recording medium, in directions orthogonal to the predetermined feeding direction, for effecting printing on the recording medium while moving within a range of printing motion which is larger than a width of the recording medium. Further, the ink jet recording head is controlled such that the ink jet recording head ejects ink droplets toward an area aside from the recording medium within the range of printing motion to carry out a flushing operation of ejecting ink droplets regardless of contents to be printed during a printing process.

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： 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.
