  • Publication number: 20220016907
    Abstract: An information processing apparatus includes an acquisition unit, a decision unit, a determination unit, and a change unit. The acquisition unit acquires a measurement result regarding a printing medium characteristic value. The decision unit decides a candidate for a printing medium type based on the acquired measurement result, and a reference characteristic value of each of printing media types set in advance to identify a type of the measured printing medium. Information associated with the printing medium type to be printed is input. The determination unit determines whether to change the reference characteristic value of the printing medium type associated with the input information based on the measurement result and the printing medium type associated with the input information. Wherein, when the determination unit determines to change the reference characteristic value, the change unit changes the reference characteristic value of the printing medium type based on the measurement result.

  • Patent number: 11025791
    Abstract: An information processing apparatus is configured to control an operation to determine a type of a printing medium to be printed by a printing unit, determine a type of printing medium indicated by information input by an input unit as the type of the printing medium to be printed, and be capable of executing a measurement mode and a designation mode. In the measurement mode, the type of the printing medium to be printed is determined by using a measurement result and a reference characteristic values set in advance. In the designation mode, the type of the printing medium to be printed is determined without using the measurement result. The information processing apparatus is configured to, even in the designation mode, change the reference characteristic value set in advance for the type of printing medium indicated by the information input by the input unit based on the measurement result.

  • Publication number: 20210024315
    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.

  • 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.
