20100044947 | RECORDING APPARATUS AND RECORDING METHOD - A recording apparatus includes a conveying roller and an ejection roller for conveying a recording medium. The recording apparatus also includes a controller which controls the conveying roller and the ejection roller. The controller selectively performs a conveyance control process for the rollers when the recording medium leaves the conveying roller. | 02-25-2010 |
20100045725 | APPARATUS AND METHOD FOR RECORDING - A recording apparatus has a controller that controls a conveying roller and a discharge roller for conveying a recording medium. The controller controls the rotation phases of the conveying roller and the discharge roller when the recording medium leaves the conveying roller before the recording medium enters the conveying roller. | 02-25-2010 |
20120268516 | APPARATUS AND METHOD FOR RECORDING - A recording apparatus has a controller that controls a conveying roller and a discharge roller for conveying a recording medium. The controller controls the rotation phases of the conveying roller and the discharge roller when the recording medium leaves the conveying roller before the recording medium enters the conveying roller. | 10-25-2012 |
20130010026 | RECORDING APPARATUS AND RECORDING METHOD - A recording apparatus to record an image on a recording medium using a recording head includes a first conveying roller, a second conveying roller, and a controller. The first conveying roller is positioned upstream of the recording head in a conveying direction and the second conveying roller is positioned downstream of the recording head in the conveying direction. In response to a first conveying mode being selected, the controller performs a rotational phase control in which the controller controls rotational phases of the first conveying roller and the second conveying roller such that the recording medium is conveyed by predetermined sections of circumferences of the first conveying roller and the second conveying roller when a trailing end of the recording medium passes the first conveying roller. In response to the second conveying mode being selected, the controller does not perform the rotational phase control. | 01-10-2013 |
20140078206 | PRINTING APPARATUS, CONVEYING APPARATUS, AND CONTROL METHOD - A printing apparatus includes a printing unit, first and second conveying units conveying a printing medium, a driving unit driving the first and second conveying units, and a control unit controlling the driving unit. The conveyance state of the printing medium makes transition from a first conveyance state in which the printing medium is conveyed only by the first conveying unit to a second conveyance state in which the printing medium is conveyed by both the first and second conveying units. The control unit controls the driving unit based on a fluctuation in a load that mutually acts between the first and second conveying units through the printing medium to suppress a fluctuation in a conveyance amount at the time of the transition of the conveyance state from the first conveyance state to the second conveyance state. | 03-20-2014 |
20140078207 | PRINTING APPARATUS AND CONTROL METHOD - A printing apparatus includes a printing unit, a first and second conveying units conveying a printing medium, a driving unit driving the conveying units and a control unit controlling the driving unit. A load mutually acting on the conveying units through the medium in a conveyance state by the conveying units is recursively calculated for each predetermined conveyance unit while setting the initial value to 0. The driving unit is controlled based on the calculation result at the time of the transition to suppress a fluctuation in a conveyance amount at the time of the transition of the conveyance state of the medium from the conveyance state by the conveying units to a conveyance state only by the second conveying unit. | 03-20-2014 |
20140078210 | CONVEYANCE APPARATUS AND RECORDING APPARATUS - The conveyance apparatus includes a first conveyance unit configured to convey a sheet in a conveyance direction, and a second conveyance unit disposed on a downstream side of the first conveyance unit in the conveyance direction and configured to convey the sheet in the conveyance direction. The conveyance apparatus corrects a rotational amount of each conveyance unit using a correction value dedicated to each rotational phase of each conveyance unit for each conveyance state, in a first conveyance state in which the first conveyance unit is operative to convey the sheet, a second conveyance state in which the first and second conveyance units are cooperative to convey the sheet, and a third conveyance state in which the second conveyance unit is operative to convey the sheet. | 03-20-2014 |
20150097890 | APPARATUS AND METHOD FOR RECORDING - A recording apparatus has a controller that controls a conveying roller and a discharge roller for conveying a recording medium. The controller controls the rotation phases of the conveying roller and the discharge roller when the recording medium leaves the conveying roller before the recording medium enters the conveying roller. | 04-09-2015 |
