A printing apparatus includes a fixing unit configured to fix an image onto a printing medium by heating the printing medium on which the image is printed, a measuring unit configured to measure each of a length of the printing medium at a first temperature, a length of the printing medium after heating of the printing medium in the fixing unit at a second temperature being a glass transition point of a material of the printing medium, and a length of the printing medium after heating of the printing medium in the fixing unit at a third temperature, and a determining unit configured to determine a fixation temperature to be used for the printing medium, based on the measured lengths.

Printing apparatus and control method of printing apparatus

A sheet feeding device includes a drive unit that rotates a roll of a wound sheet in a first direction and in a second direction, a sensor having an output which changes according to a distance between a detecting position facing a peripheral surface of the roll and the peripheral surface of the roll, and a control unit that determines an amplification factor of the sensor on the basis of data. The data is acquired by changing the amplification factor while the roll is rotated once in the second direction and includes a plurality of the output values acquired at different rotation angles.

Sheet feeding device and printing apparatus

A roll sheet with a continuous sheet wound in a roll form is rotated in a forward direction to supply the sheet to a printing unit. A sensor whose output is changed in accordance with a distance between the sensor and the sheet is used. A rotation direction of the roll sheet is switched from an opposite direction to the forward direction on the basis of the output of the sensor during rotation of the roll sheet in the opposite direction.

Printing apparatus

An object of the present disclosure is to implement, at a low cost, highly accurate color calibration in a printing apparatus that performs printing using fluorescent ink. One embodiment of the present invention is an image processing apparatus that includes: a processing unit configured to perform processing relating to color calibration in a printing apparatus that prints an image on a printing medium using fluorescent printing material; and an execution unit configured to perform calibration processing of the printing apparatus based on a measured value that is obtained by measuring a patch chart for obtaining information on an amount of application of the fluorescent printing material in the printing apparatus, wherein a patch included in the patch chart is printed with the fluorescent printing material and subtractive color mixture printing material and at least one dot of the subtractive color mixture printing material covers a dot of the fluorescent printing material.

Image processing apparatus, image processing method, and storage medium

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.

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.

Sheet supplying apparatus and printing apparatus

An information processing apparatus includes an acquisition unit configured to acquire a measurement result obtained by a measurement unit that measures a characteristic of a print medium to be used in a printing apparatus, a notification control unit configured to cause a notification unit to provide notification of information indicating a print media type, and a storage unit configured to store information on a predetermined characteristic of each of a plurality of print media types, wherein, based on the measurement result acquired by the acquisition unit and usage history information indicating print media types used in the printing apparatus, the notification control unit causes the notification unit to provide notification of information indicating a print media type for which information on the predetermined characteristic stored in the storage unit corresponds to a characteristic indicated in the measurement result and which has a usage history indicated in the usage history information.

Information processing apparatus, printing apparatus, and method of determining print media type

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.

Information processing apparatus, printing apparatus, and information processing method

A membrane electrode assembly includes a polyelectrolyte membrane having a first surface and a second surface facing away from the first surface; a fuel-electrode-side electrocatalyst layer bonded to the first surface and containing a first catalytic material, a first electrically conductive carrier, and a first polyelectrolyte, the first electrically conductive carrier carrying the first catalytic material; and an oxygen-electrode-side electrocatalyst layer bonded to the second surface and containing a second catalytic material, a second electrically conductive carrier, a second polyelectrolyte, and a fibrous material, the second electrically conductive carrier carrying the second catalytic material. The membrane electrode assembly contains voids, the voids including pores each having a size in a range of 3 nm or more and 5.5 &#x3bc;m or less.

Membrane electrode assembly and polymer electrolyte fuel cell

An information processing apparatus includes an acquisition unit, notification control unit, input unit, and extension unit. The acquisition unit acquires a measurement result obtained by measuring a printing medium characteristic and acquires a characteristic reference range of each of printing media types set in advance to identify a type of a measured printing medium. Extracting, as a candidate printing medium and based on the acquired measurement result and the acquired characteristic reference range, a type of printing medium using the characteristic reference range including the measurement result and notifying information indicating the type of the candidate printing medium are performed. The input unit inputs information, wherein a type of printing medium on which recording is to be performed by the recording unit has a first reference range which is the characteristic reference range of the type and corresponds to the input information. The extension unit extends the first reference range.
