摘要:
There is disclosed a dot forming method and a recording apparatus, suitable for unprocessed recording medium, such as plain paper having fluctuation in its ink absorbing ability, or a plastic sheet with low ink absorbing ability. At the formation of each pixel with plural dots, the dots are so distributed that they are not continuous but are mutually complementary in the transverse and longitudinal directions of the pixel and also at least in the boundary area of adjacent pixels.
摘要:
In a recording apparatus for recording on a recording medium by a plurality of recording heads, a scan unit has a carriage capable of mounting the recording heads at a predetermined interval and causes the recording heads to scan corresponding divided recording areas. A record control unit causes the recording heads to conduct a first record mode to record an area of a first recording width in a direction of scan by shared recording by the recording heads of the corresponding recording areas and a second record mode to record an area of a second recording width smaller than the recording width of the first recording width by causing at least one of the recording heads to record in the corresponding divided recording area when the corresponding divided recording areas are scanned. A distance between two recording apparatus mounted at outermost positions in the arrangement of the recording heads on the carriage is not larger than a difference between the first recording width and the second recording width.
摘要:
The present invention provides a recording apparatus which can determine a position of a carriage on which a recording head is mounted with high accuracy without enhancing positional accuracy of a carriage position detecting system. In this recording apparatus, a rod-like member is moved upwardly to be engaged by a recessed portion formed in the carriage. A deviation amount of the carriage generated by such engagement is detected by a linear encoder and is used as a correction value when the carriage is moved next time.

A recording apparatus is provided with a paper supply stacker on which sheets are stacked and held, a recording head for effecting recording on the sheets fed out from the paper supply stacker, a flat support device for supporting the sheets during the recording by the recording head, and a discharged paper stacker onto which the sheets recorded by the recording head are discharged.
摘要:
Ink jet recording encounters deviations in the position at which a recorded dot is applied due to changes in the distance from the recording head to a recording medium, the carriage movement speed and the ink discharge speed or the like. When bidirectional recording is performed while moving the carriage having the recording head mounted thereon, deviations of the recorded dot may occur in the forward and rearward recording operations. The present invention is arranged in such a manner that values for correcting the deviations occurring in bidirectional recording and corresponding to the changes of the distance from the recording head to a recording medium, the carriage movement speed and the ink discharge speed or the like are previously stored. A drive signal, the timing of which has been corrected with the correction value, is used to operate the apparatus so that high-quality recordings free from deviations occurring in the bidirectional recording operation are obtained. The present invention disclosed a recording apparatus having a plurality of recording heads mounted on a carriage thereof, the recording apparatus being arranged in such a manner that the carriage movement speed is detected to determine the recording timing of the plural recording heads to prevent the deviation of dots formed by the plural recording heads due to the changes in the moving speed caused by changes in the environment of the apparatus to record high quality images.
