摘要： A media alignment method includes printing a calibration pattern on a media in a print one by a printhead including forming a first corner identification marker at a first corner of a reference edge of the media, a second corner identification marker at a second corner of the reference edge, and a linear identification marker. The method also includes capturing the calibration pattern by an image capturing unit. The method also includes determining a printhead axis based on the linear identification marker, determining a default printhead origin based on the printhead axis and the linear identification marker, and determining a media origin based on the printhead axis, the first corner identification marker, and the second corner identification marker. The method also includes determining an offset compensation parameter by the determination module corresponding to a distance between the default printhead origin and the media origin.

摘要： An apparatus includes an acquisition unit and a controller. The acquisition unit is configured to, in a case of a recording medium having different thicknesses along a direction crossing a feeding direction in which the recording medium is fed by a feeding unit, acquire correction information that is set on the basis of an orientation of the recording medium in a case where the recording medium is fed by the feeding unit. The controller is configured to move a print start position of a print unit in the direction crossing the feeding direction on the basis of the correction information acquired by the acquisition unit.

摘要： Sub-pixel alignment is performed for dots from multiple printheads. In order to align, output from a first printhead is aligned with output from a second printhead, dot data is generated for the first printhead and for the second printhead. The dot data is generated from data input. The dot data indicates location of dots on a print medium. Dot shift data is used in order to make sub-pixel shifts in locations of first dots placed on the print medium by the first printhead in order to align the first dots placed on the print medium by the first printhead with second dots placed on the print medium by the second printhead. The first dots and the second dots are then placed on the print medium.

摘要： A liquid ink printer, depositing ink drops to form an image, including a pagewidth printbar, movable to print a complete image when defective nozzles of the printbar are identified. A positioning device, coupled to the pagewidth printbar, positions the printbar at a plurality of discrete locations, to move a functioning nozzle to the location in the image where the defective nozzle should deposit drops of ink. Defective nozzles are identified by the printer control mechanism and a user is given the option to fix the image through a user interface where the printer is directed to fill in the missing information of the image. Defective nozzles can also be identified by printing a test pattern which identifies to a user which of the nozzles are non-functioning. The user then inputs this information to the printer.

摘要： In a printing apparatus for performing a print operation by scanning a print head having a plurality of printing elements in a direction perpendicular to the convey direction of a recording medium, a divisional print operation is performed by using the print head upon setting print timing differences for a plurality of blocks obtained by dividing the plurality of printing elements. In this case, a command to finely change the print timing differences is input through an input unit, and the print operation is controlled to perform a divisional print operation by finely adjusting the print timing differences on the basis of the command.

摘要： Using a recording head with 8 nozzles, and feeding paper or recording medium by an amount equal to 2 nozzles at each recording scan, recording is made with respect to first and second rasters in a first recording scan by #7 and #8 nozzles. At this moment, the #7 nozzle has a SMS printing rate of 1/3, and the #8 nozzle has a printing rate of 1/4. Initial values of a context memory are both 0. After the paper is fed by 2 nozzle distance, in a second recording scan, first--fourth rasters are recorded by #5-#8 nozzles. Rasters to be recorded are increased by 2 at every paper feed by 2 nozzle distance, and after 8 rasters, the rasters to be recorded are decreased by 2. Since the printing rate of the odd number nozzle is larger than that of the even number nozzle, an odd numbered raster is recorded partly two times by the odd number nozzle, thereby making emphasis printing uniformly over the entire image.

摘要翻译： 使用具有8个喷嘴的记录头，并且在每次记录扫描时将纸或记录介质送入等于2个喷嘴的数量，在＃7和＃8喷嘴的第一次记录扫描中对第一和第二光栅进行记录。 此时，＃7喷嘴具有+ E，1/3 + EE的SMS打印速率，＃8喷嘴的打印率为+ E，为1/4 + EE。 上下文存储器的初始值都为0。在纸张以2个喷嘴距离馈送纸张之后，在第二次记录扫描中，＃5＃8喷嘴记录第一至第四个光栅。 要记录的光栅在每个进纸处增加2个喷嘴距离，在8个光栅之后，要记录的光栅减少2.由于奇数喷嘴的打印率大于偶数喷嘴的打印速率 ，奇数编号的光栅被奇数喷嘴部分地记录两次，从而在整个图像上均匀地印刷。
