A reference value of a characteristic value of an unset recording medium is determined based on correction values for types of recording media stored in an electrically erasable programmable read-only memory (EEPROM) in advance and a result of measurement of the unset recording medium.

System, information processing apparatus, method for determining type of recording medium, and storage medium

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

Information processing apparatus, printing apparatus, information processing method, and storage medium

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.

Information processing apparatus, printing apparatus, information processing method, and program, providing accurate identification of the type of a printing medium by increasing the opportunity to improve the accuracy of determining the type of printing medium based on measurement results

A reading apparatus includes a reader that obtains image data by reading a reading target, a platen on which a document to be read by the reader located at a first position is set, a first member read by the reader located at the first position if there is no document on the platen, a second member read by the reader located at a second position, which is different from the first position, and a determination unit that performs a determination process for determining whether the document is set on the platen on the basis of a first output, which is obtained if the reader located at the first position reads the reading target, and a second output, which is obtained if the reader located at the second position reads the reading target.
