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： When it is determined that an end process flag is not stored in memory, there is a possibility that the recovery operation was not executed normally and the viscosity increased or fixed coating liquid exist in a liquid holding member and liquid flow paths. Therefore, a filling operation for generating stronger fluidization than a normal filling operation is carried out as a filling operation also acting as a restoration operation. That is, a pump is operated at a predetermined rotating speed for a specified time, which is longer than the specified time for the normal filling operation. By this, the viscosity increased coating liquid existing in the liquid holding space and the respective liquid flow paths is re-fluidized to an extent that will not interfere with circulation, and normal filling of the coating liquid is carried out.

摘要： The present invention provides a liquid applying apparatus that prevents 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 been 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： 本发明提供一种液体涂布装置，其防止施胶辊长时间与涂布液接触而劣化。 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已经完成之后，在一段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： For a serial color ink jet printing apparatus that forms an image using a symmetric printing head that ejects large dots and small dots, the configuration of a printing head is provided for suppressing, to the extent possible, a cyclic fluctuation in the main scanning direction. According to the present invention, individual nozzle arrays are arranged so that two nozzle arrays, i.e., a cyan nozzle array c1 and a magenta nozzle array m1, that are located nearer each other, form dots on adjacent scan lines. With this arrangement, a high quality image, having neither an uneven density nor an uneven color, can be formed when a printing head is inclined, or when a cyclic shift in printing positions occurs, depending on the position of the main scanning direction.

摘要： A liquid applying apparatus can prevent an applying liquid from evaporating while an applying operation is stopped and can reliably prevent the liquid from leaking even when, for example, the posture of the apparatus is tilted. An abutting member of a holding member is abutted, under an urging force of a spring, against an applying surface of an applying roller. Thus, a liquid holding space is formed between the applying roller and a holding member to hold the applying liquid. The abutting member is annularly formed of a single member. The applying roller rotates to cause the applying liquid held in the holding space to adhere to an outer peripheral surface of the applying roller. The applying liquid is then applied to the applying medium.

摘要： A thermal demand priority type cogeneration system, is made operative for obtaining power output without thermal demand. When the temperature in a hot water tank 17 is low, a heat request is output from a heat request generator 42 and thereby an engine 11 is driven. When the temperature T higher than a predetermined temperature T1, a first water supply instructing unit 44 opens a valve 39 and supplies water to the tank 17 to decrease the water temperature T. When the water temperature goes down, thermal demand is generated, the engine 11 is driven according to the heat request. So as to generate thermal demand, a discharge valve 41 may be opened when the water temperature T is at the predetermined temperature or higher. A second water supply instructing unit 46 opens the valve 39 when reserved water level in the tank 17 goes down. When the valve 39 is opened, water is supplied and the water temperature goes down and thermal demand is generated. At a power failure of a commercial electric power system 14, thermal demand is generated forcibly.

摘要： A liquid applying apparatus and an ink jet printing apparatus can reduce evaporation that may occur when an application liquid is left in a liquid holding member for a long time. The liquid holding member forms a space between an elastic member and a roller to hold the application liquid. The apparatuses also are capable of preventing the leakage of the liquid from the liquid holding member regardless of a variation in the posture of the apparatus. In collecting the application liquid from the liquid holding member to a storage tank, the apparatuses switch a selector valve to allow an air communicating port and a tube to communicate with each other. The apparatuses further drive a pump to collect the application liquid from a liquid applying member and channel to the storage tank. Once the collecting is finished, the air communicating valve is closed.

摘要： An image forming apparatus is capable of specifying the type of an occurring abnormality to a certain extent while avoiding the increasingly complicated control that is caused when a plurality of abnormalities is detected individually according to the presence of their respective causes. A normal group data set, which is a collection of normal value combinations relating to grouped information constituted by a plurality of information of differing types, is stored in RAM or ROM serving as information storage device of a control unit. At least two or more sets of grouped information, including first grouped information constituted by a plurality of different types of information, and second grouped information constituted by a plurality of information in a different combination to that of the first grouped information, are obtained from the RAM, the ROM, various sensors, and an operation display unit.
