摘要： This invention relates to a printing apparatus and a conveyance control method capable of allowing even an arrangement having a plurality of conveyance rollers in a printing medium conveyance path to accurately control conveyance of a printing medium. According to this invention, a first encoder detects a conveyance amount by a first conveyance roller, provided in a conveyance path, for conveying a printing medium. A second encoder detects a conveyance amount by a second conveyance roller provided in the conveyance path in the conveyance direction of the printing medium at the downstream side of the first conveyance roller for conveying the printing medium. On the other hand, a signal output from the first or second encoder is selected on the basis of the position of the printing medium on the conveyance path. Conveyance of the printing medium is controlled on the basis of the selected output signal.

摘要： This invention relates to a printing apparatus and a conveyance control method capable of simultaneously operating plural encoder sensors and executing more accurate printing medium conveyance control. A first encoder sensor provided adjacent to a first conveyance roller detects the conveyance amount of a printing medium by the first conveyance roller provided in the conveyance path of the printing medium. A second encoder sensor provided adjacent to a second conveyance roller detects the conveyance amount of the printing medium by the second conveyance roller provided in the conveyance path of the printing medium at the downstream side from the first conveyance roller in the conveyance direction of the printing medium. For example, conveyance of the printing medium is controlled on the basis of the output signals from the first and second encoder sensors when a tail end of the printing medium is located adjacent to the first conveyance roller.

摘要： A recording apparatus for forming images using a recording head includes a feeding roller, a conveying roller, a conveyance control unit, and a recording control unit. The conveyance control unit performs a conveying operation a number of times after the trailing end of a sheet reaches a predetermined position defined between the feeding roller and the conveying roller such that the trailing end of the sheet is disposed in a predetermined range upstream of the conveying roller in a sheet conveying direction after the conveying operations. At least one of the conveying operations performed a number of times is performed based on a distance from the position of the trailing end of the sheet to the position of the conveying roller.

摘要： A control system for an internal combustion engine is disclosed. The engine has an exhaust gas recirculation device which includes an exhaust gas recirculation passage for recirculating exhaust gases from the engine to an intake system of the engine, and an exhaust gas recirculation control valve provided in the exhaust gas recirculation passage, for controlling a flow rate of the exhaust gases. An air-fuel ratio control amount is calculated based on an output of the air-fuel ratio sensor provided in the exhaust system of the engine. The air-fuel ratio of the air-fuel mixture supplied to the engine is controlled with the air-fuel ratio control amount. A failure of the exhaust gas recirculation device is determined based on a changing component of the air-fuel ratio control amount when changing an opening of the exhaust gas recirculation control valve in a predetermined cycle.
