摘要： In order to stabilize a performance of a pump employed for processing in an inkjet printing apparatus such as sucking ink from a printing head with a low cost configuration and without the need of using any specific detecting unit, the following configuration is employed. Namely, a tube pump having a member with a curved surface aligned with a flexible tube for supporting the tube and a roller which moves while pressing (squeezing) the flexible tube is driven with a DC motor. To keep revolutions always constant, a current PWM control is employed for changing a power applied to the motor according to load fluctuations, and a phase of the roller is determined based on the current PWM value to manage a pressure generated by the pump and a discharge rate.

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： 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. A pattern having a predetermined uniform density is printed on a printing medium a plurality of number of times by using a printhead while conveying the printing medium and changing the conveyance amount by a small amount. A conveyance correction amount obtained on the basis of the conveyance amount upon printing a pattern selected from a plurality of printed pattern is stored in a storage medium. Conveyance of the printing medium is controlled while correcting the conveyance amount of the printing medium by the conveyance means on the basis of the conveyance correction amount stored in the storage means.

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.
