Abstract
In the present invention, a conveying operation of a recording medium is controlled on the basis of a first correction value and a second correction value. The first correction value is used for correcting a conveying amount when the recording medium disengages from a first conveying roller, and the second correction value is used for correcting the phase of the first conveying roller and a second conveying roller when the recording medium disengages from the first conveying roller before the recording medium is nipped by the first conveying roller.
Claims9
A recording apparatus that performs recording by using an ink-discharging recording head, the recording apparatus comprising:
- a first conveying roller disposed upstream relative to the recording head in a conveying direction of a recording medium and configured to convey the recording medium;
- a second conveying roller disposed downstream in the conveying direction and configured to convey the recording medium;
- and
- a controller configured to control a conveying operation of the recording medium on the basis of a first correction value and a second correction value, the first correction value being used for correcting a conveying amount when the recording medium disengages from the first conveying roller, the second correction value being used for correcting the phase of the first conveying roller and the second conveying roller when the recording medium disengages from the first conveying roller before the recording medium is nipped by the first conveying roller,
- wherein the controller switches the use of the first correction value and the second correction value in accordance with a conveyance path of the recording medium.
A recording method for performing recording by using an ink-discharging recording head, the method comprising:
- a conveying step of conveying a recording medium by using a first conveying roller disposed upstream relative to the recording head in a conveying direction of the recording medium and configured to convey the recording medium and by also using a second conveying roller disposed downstream in the conveying direction and configured to convey the recording medium;
- and
- a controlling step of controlling a conveying operation of the recording medium on the basis of a first correction value and a second correction value, the first correction value being used for correcting a conveying amount when the recording medium disengages from the first conveying roller, the second correction value being used for correcting the phase of the first conveying roller and the second conveying roller when the recording medium disengages from the first conveying roller before the recording medium is nipped by the first conveying roller,
- wherein the controlling step includes switching the use of the first correction value and the second correction value in accordance with a conveyance path of the recording medium.
