Abstract:
An apparatus may include a print head, multiple roller pairs to convey a sheet, a direct sensor, and a control unit. The print head prints on a conveyed sheet. The multiple roller pairs nip the sheet at an upstream side of the print head to convey the sheet, nip the sheet at a downstream side of the print head, and nip the sheet at an upstream side of a first roller pair to convey the sheet. The direct sensor measures a surface of the conveyed sheet at a measurement position between a nip position of the first roller pair and a nip position of a third roller pair to obtain information relating to a movement state of the sheet. The control unit controls to correct at least one of driving control of the print head and conveying control of the sheet, based on the information obtained by the direct sensor.
