摘要： In an ink jet printing apparatus using many types of inks to execute bidirectional printing, if ejection opening rows for yellow, magenta, and cyan inks are symmetrically arranged, ejection opening rows for a black ink are arranged adjacent to the most inside ejection opening rows for the yellow ink. Thus, a difference in color between forward scanning and backward scanning is determined by a difference in coloring between the black ink and the yellow ink. In this case, a possible color drift attributed to bidirectional printing can be suppressed by selecting the inks so that the difference in coloring between the black ink and the yellow ink is smaller than that between the black ink and the other color inks.

摘要： The present invention provides an inkjet recording apparatus and a recording apparatus capable of reducing wear of a roller for application, even if liquid (for example, application liquid) is insufficient in a case where liquid is applied to recording media. In an embodiment of the present invention, in a case where it is determined that the application liquid is sufficient in a storage tank, the application liquid is filled in a liquid retention space, the application liquid is applied to the recording medium, and thus recording is performed. In a case where it is determined that the liquid application is insufficient in the storage tank, recording with application is prohibited.

摘要： The present invention provides a liquid application device, an inkjet recording apparatus and a recording apparatus, which are capable of performing an adequate application initial operation according to the length of waiting time and power-off time, as well as a method of controlling the liquid application device. In the present invention, information on an end time of the previous processing for collecting liquid is read from a nonvolatile memory, current time information indicating the current time is obtained, and information on a lapse of time from the end time of the previous collection to a start time of the current application. Thereafter, the number of preliminary rotations R of an application roller is decided based on the information on the lapse of time with reference to a look-up table. Sequentially, the application roller is rotated by the decided number of preliminary rotations R to perform preprocessing operation.

摘要： An inkjet printing apparatus is provided which minimizes the amount of inks consumed for preventing the sedimentation of ejected inks on the platen ink absorber and which can effectively prevent the sedimentation of inks. To this end, a comparison is made between the ejected volume of easily sedimenting inks and the ejected volume of sedimentation restraining inks in terms of ink components. If the ejected volume of the sedimentation restraining inks is found not enough, a required amount of sedimentation restraining ink is additionally ejected.

摘要： A liquid applying apparatus can prevent an applying roller from being degraded while contacting with an application liquid for a long time. Specifically, once an applying operation has been completely executed on an applying medium, the apparatus stands by for 60 seconds while holding the application liquid in a liquid holding member. When an applying instruction is not given during this period, the apparatus performs an application liquid collecting operation of discharging the application liquid from the liquid holding member. Thus, upon determining that no applying operation has been performed for a certain period after one applying operation has finished, the apparatus collects the application liquid from the liquid holding member. This avoids immersing the applying roller in the application liquid for a long time. Therefore, the applying roller is prevented from being degraded by the application liquid.

摘要翻译： 液体涂布装置可以防止涂布辊在长时间接触涂布液时劣化。 具体地说，一旦在施加介质上完成了涂布操作，则将该涂布液保持在液体保持部件中的状态下，待机60秒钟。 当在此期间没有给出施加指令时，装置执行从液体保持构件排出施用液体的施用液体收集操作。 因此，一旦确定在一次施加操作完成之后一定时间内没有执行施加操作，则装置从液体保持构件收集施用液体。 这样可以避免长时间将涂布辊浸入涂布液中。 因此，防止涂布辊被涂布液劣化。

摘要： An image forming apparatus including a conveyance unit to convey a transfer medium, a first image forming unit to form a monochrome image transferred at a first transfer position onto the transfer medium, and a second image forming unit disposed downstream from the first image forming unit in a direction of conveyance of the transfer medium, including an intermediate transfer body to form a multi-colored toner image on the intermediate transfer body. The multi-colored toner image is transferred onto the transfer medium at a second transfer position. The conveyance unit is separated from the intermediate transfer body at the second transfer position in a monochrome mode to form the monochrome image using only the first image forming unit, and contacts the intermediate transfer body at the second transfer position in a full-color mode to form a full-color image using both the first and second image forming units.

摘要： A liquid application device and an inkjet recording apparatus are capable of reducing nonuniformity in application of liquid onto a recording medium, and thereby forming high-quality images on a steady basis. In the present invention, information indicating the lapse of time after the previous circulation operation is obtained. Subsequently, based on the obtained information indicating the lapse of time, a preliminary circulation sequence is determined. Finally, the preliminary circulation sequence is performed based on the determined preliminary circulation sequence.
