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 time point at which a predetermined period elapses since the start of use of a copying machine as a detection subject after factory shipment or repair is obtained. Pieces of set information, which are combinations of various types of information until the time point is reached are sequentially stored to construct a normal set information group. After the time point is reached, presence of abnormality in the copying machine is determined based on the normal set information group and the various types of information obtained.

摘要： In a print head having arrays of large nozzles and small nozzles with different ink ejection volumes that are connected to a common ink chamber, the preliminary ejection operation is performed 29,000 times first on only the large nozzles at an ejection frequency of 10 kHz to discharge viscous or mixed color ink from ink chambers. After the preliminary ejection operation of the large nozzles is finished, only the small nozzles are made to perform the preliminary ejection operation 2,000 times at an ejection frequency of 10 kHz. Reducing the number of preliminary ejections from the small nozzles in this manner can minimize the generation of stray mist. Further, by performing the preliminary ejection operation on the large nozzles first, it is possible to discharge enough viscous ink from the ink chamber.

摘要： A necessary amount of suppression ink is applied to each portion of an ink absorber in a short time and in an efficient manner. For that end, carriage scan is performed while changing an ejection condition of suppression ink so as to change an application amount of suppression ink according to a position of an ink absorber. This makes it possible to appropriately apply suppression ink, which suppresses accumulation of ink, to the entire area of the ink absorber by carriage scan in a short time even if an application amount of accumulation ink differs from part to part of the ink absorber.

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.
