Abstract: According to an ink replacement method in an ink-jet recording apparatus that includes a recording head having an ink ejection face in which a plurality of nozzles for ejecting ink onto a recording medium are arranged, a sub-tank that temporarily stores the ink fed from an ink container, and an ink flow passage through which the ink circulates from the sub-tank via the recording head to the sub-tank, gas is inserted between first ink present in the ink flow passage and second ink newly supplied to the recording head via the ink flow passage to form a gas-liquid interface between the first and second ink and gas, and then the first ink is replaced with the second ink.

Abstract: The inkjet recording apparatus includes a plurality of line heads each including a recording head, a plurality of waste ink collection containers, a display portion that indicates states of the line heads and the waste ink collection containers, and a control portion that detects the states of the line heads and the waste ink collection containers and controls display portion. In a case where an unused line head or an unused waste ink collection container exists and where a recording head in one of the line heads in use or one of the waste ink collection containers in use needs to be replaced, the control portion indicates, on the display portion, the recording head in the unused line head or the unused waste ink collection container as a recording head available for replacement or a waste ink collection container available for replacement.

Abstract: An image forming apparatus has a sheet feed portion, a conveying portion, a control portion, a first sensor having the detection position at a first position in the sheet conveying passage, and a second sensor having the detection position at a second position downstream of the first position in the sheet conveying direction. The control portion performs first sensing to sense whether the sheet's rear end has passed the first position within a first time of the start of the feeding and second sensing to sense whether the sheet's rear end has passed the second position within a second time of the start of the feeding, Even if the control portion is unable to sense passage of the sheet's rear end in the first sensing, when it senses passage of the sheet's rear end in the second sensing, it makes the conveying portion continue feeding the sheet.

Abstract: Provided is a sheet conveying device capable of suppressing the recurrence of overlapped feeding in accordance with the detection of overlapped feeding. The sheet conveying device includes a paper-supply roller and a conveying roller. A sheet-detecting unit detects a leading edge position of a sheet. An overlapped-feeding-detecting unit detects overlapped-feeding of sheets. An overlapped-feeding-distance-calculating unit, based on detection results, calculates an overlapped-feeding distance in which sheets are overlapped. A conveyance-control unit causes the paper-supply roller to stop at a timing when a position separated a set length in a sheet-conveyance direction from a sheet trailing edge reaches the paper-supply roller. The conveyance-control unit, in a case where detection of overlapped feeding by the overlapped-feeding-detecting unit occurs a plurality of times, extends the set length based on the overlapped-feeding distance.
