  • Patent number: 11639068
    Abstract: An information processing apparatus includes a type reception unit, a notification unit, a mode reception unit, and a determination unit. The mode reception unit receives a mode selected from among a plurality of modes for determining a determined type of recording medium for use in a recording apparatus, wherein the information processing apparatus is configured to perform operations including determining, in a designation mode, a selected type of recording medium indicated by information received by the type reception unit, and determining, in an automatic determination mode, an automatically determined type of recording medium for use in the recording apparatus without receiving input user information indicating the recording medium type. In response to the determination unit determining that the mode is able to be changed from the designation mode to the automatic determination mode, the notification unit issues a prompting notification to prompt a user to change the mode.

  • Patent number: 11577927
    Abstract: A sheet supplying apparatus, which is capable of winding a sheet tightly, includes a driving unit configured to cause a roll including a wound consecutive sheet to rotate in a first direction for feeding the sheet or a second direction opposite to the first direction, a sensor that detects a leading end portion of the sheet separated from an outer circumferential surface of the roll, and a contact body that presses the outer circumferential surface. Before the sheet is fed, in a state in which the contact body presses the outer circumferential surface, the driving unit causes the roll to continuously rotate in the second direction until a detection cycle of the leading end portion by the sensor is less than a predetermined value.

  • Publication number: 20210354483
    Abstract: There is provided a printing apparatus. A first roller nips and conveys, in a conveyance direction, a printing medium. A second roller nips and conveys a printing medium at a downstream side of the first roller in the conveyance direction. A print unit prints an image on a printing medium conveyed by the second roller. A control unit, until printing by the print unit reaches a vicinity of a trailing end of a print length, sets a nip pressure of the first roller to a first pressure, and when printing by the print unit reaches the vicinity of the trailing end of the print length, sets the nip pressure of the first roller to a second pressure that is greater than the first pressure.

  • Patent number: 10926558
    Abstract: A print apparatus includes a holding unit to hold a roll sheet obtained by winding a sheet, a driving unit, a separation flapper, a pressure contact roller, a print unit, a displacement sensor, and a control unit. The driving unit rotates the held roll sheet. The separation flapper follows a roll sheet surface to separate the sheet from the roll sheet. The pressure contact roller comes into pressure contact with the roll sheet surface. The print unit prints an image on the sheet supplied by rotating the roll sheet in pressure contact with the pressure contact roller in a forward direction. The displacement sensor detects a separation flapper displacement amount according to separation flapper rotation when the sheet is supplied to the print unit after a roll sheet front end is detected. The control unit stops the roll sheet rotation when the amount of displacement exceeds a threshold.

  • Publication number: 20200369049
    Abstract: A roll sheet, in which a continuous sheet is wound in a roll form, is caused to rotate in a forward direction to supply the sheet to a printing unit. First and second sensors are arranged at positions facing an outer circumferential surface of the roll sheet and deviated in an axis line direction of the roll sheet. Outputs of the first and second sensors are changed in accordance with a distance to a sheet of the roll sheet. A rotation direction of the roll sheet is switched from a forward direction to a reverse direction on the basis of the outputs of the first and second sensors while the roll sheet is being rotated in the reverse direction.

  • Patent number: 10597247
    Abstract: Automatic sheet feeding of an installed roll is performed more reliably. To this end, a leading end of a sheet is detected on the basis of a change in an output value of a sensor while causing a roll to rotate in a winding direction using a sensor capable of detecting a distance to the sheet separated from the roll. After the detection, the roll is caused to rotate in a feeding direction, and a feeding state of the sheet is determined on the basis of a change in the output value of the sensor.

  • Patent number: 10421299
    Abstract: In a sheet supply apparatus, a type of sheet to be used can be specified using a sensor that detects a sheet separated from a roll at the time of automatic sheet feeding. The sheet supplying apparatus includes a driving unit configured to cause a roll including a wound consecutive sheet to rotate in a first direction for feeding the sheet or a second direction opposite to the first direction, a sensor that detects the sheet separated from an outer circumferential surface of the roll, and a specifying unit. In a case in which the sensor detects a leading end portion of the sheet while the roll is being rotated in the second direction, the driving unit changes a rotation direction of the roll from the second direction to the first direction and feeds the sheet, and the specifying unit is configured to specify a type of the sheet on the basis of an output of the sensor while the roll is being rotated in the second direction.
