Claims (6)

1 . An image forming apparatus comprising: a detection unit configured to detect a feature value of a sheet being conveyed; and a selection unit configured to select a sheet type corresponding to the feature value detected by the detection unit, wherein in a case where a plurality of sheet types correspond to the feature value detected by the detection unit, the plurality of sheet types including a first sheet type having an attribution indicating a default sheet type and a second sheet type having an attribution indicating a sheet type registered by a user, the selection unit automatically selects, based on an attribution of a sheet type included in the plurality of sheet types, the first sheet type from the plurality of sheet types; and a printing unit configured to print on the conveyed sheet using a print control parameter corresponding to the first sheet type selected by the selection unit.
2 . The image forming apparatus according to claim 1 , further comprising: a display processing unit configured to cause a display unit to display information indicating the sheet type selected by the selection unit, wherein the information is an icon indicating the sheet type selected by the selection unit.
3 . The image forming apparatus according to claim 2 , wherein the information is displayed in at least part of a time period in which processing for printing using the print control parameter corresponding to the type of sheet is performed after selection of the sheet type.
4 . The image forming apparatus according to claim 1 , further comprising: a determination unit configured to determine whether a plurality of types of sheets correspond to the feature value detected by the detection unit are registered.
5 . A method for controlling an image forming apparatus, comprising: detecting a feature value of a sheet being conveyed; selecting a sheet type corresponding to the detected feature value, wherein in a case where a plurality of sheet types correspond to the detected feature value, the plurality of sheet types including a first sheet type having an attribution indicating a default sheet type and a second sheet type having an attribution indicating a sheet type registered by a user, the first sheet type is automatically selected, based on an attribution of a sheet type included in the plurality of sheet types, from the plurality of sheet types; and printing on the conveyed sheet using a print control parameter corresponding to the selected first sheet type.
6 . A non-transitory computer readable storage medium storing a program causing an image forming apparatus to perform a method, the method comprising: detecting a feature value of a sheet being conveyed; selecting a sheet type corresponding to the detected feature value, wherein in a case where a plurality of sheet types correspond to the detected feature value, the plurality of sheet types including a first sheet type having an attribution indicating a default sheet type and a second sheet type having an attribution indicating a sheet type registered by a user, the first sheet type is automatically selected, based on an attribution of a sheet type included in the plurality of sheet types, from the plurality of sheet types; and printing on the conveyed sheet using a print control parameter corresponding to the selected first sheet type.

Description

BACKGROUND Field of the Disclosure The present disclosure relates to an image forming apparatus, a method for controlling an image forming apparatus, and a storage medium. Description of the Related Art An image forming apparatus including a sensor (media sensor) that measures feature values, such as the surface property and the basis weight, of a sheet on a sheet feeding path has been developed. Such an image forming apparatus uses the media sensor to measure the feature values of a sheet being conveyed on the basis of a print job and identifies the type of the sheet from a prestored sheet database (media library) on the basis of the measured feature values of the sheet. The image forming apparatus then prints on the sheet using print control parameters corresponding to the identified type of sheet. Japanese Patent Laid-Open No. 2022-26815 describes that a user sets the print control parameters for a user define paper (the type of paper set uniquely by the user) by duplicating the print control parameters for basic paper that is prepared in advance and changing the duplicate print control parameters. Japanese Patent Laid-Open No. 2022-26815 also describes that the user define paper is defined by measuring and identifying the type of basic paper that serves as the source of duplication for the user define paper using a media sensor and enabling the user to set the print control parameters of the basic paper. However, according to the technique described in Japanese Patent Laid-Open No. 2022-26815, the image forming apparatus may not determine the sheet type at the time of printing, since the user uniquely sets the sheet type. SUMMARY Accordingly, the present disclosure prevents the happening of the occasion where an image forming apparatus cannot determine the type of sheet at the time of printing. According to an aspect of the present disclosure, an image forming apparatus includes a detection unit configured to detect a feature value of a sheet being conveyed and a selection unit configured to select the type of sheet corresponding to the feature value detected by the detection unit, wherein when a plurality of types of sheets correspond to the feature value detected by the detection unit, the selection unit automatically selects one of the plurality of types of sheets. Further features of the present disclosure will become apparent from the following description of exemplary embodiments with reference to the attached drawings. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic illustration of an image forming apparatus. FIG. 2 illustrates the internal configuration of the image forming apparatus. FIG. 3 illustrates the configuration of a media sensor. FIGS. 4A and 4B illustrate paper setting screens. FIGS. 5A and 5B illustrate paper type list screens. FIG. 6 is a flowchart of a print control process. FIG. 7 illustrates the correspondence between the feature value and the type of paper. FIGS. 8A to 8C illustrate examples of a job status display screen. DESCRIPTION OF THE EMBODIMENTS An embodiment of the present disclosure is described below with reference to the accompanying drawings. The embodiment described below is only an example, and the present disclosure is not limited to the embodiment described below. In the embodiment described below, the same reference numeral is used to identify the same configuration. First Embodiment The first embodiment is first described. Description of Image Forming Apparatus FIG. 1 schematically illustrates an example of the configuration of an image forming apparatus 100. In FIG. 1, a central processing unit (CPU) 110 is an example of a control unit that performs overall control of the image forming apparatus 100. The image forming apparatus 100 may have one or more dedicated hardware units different than the CPU 110, and the dedicated hardware units may perform at least some of the processes to be performed by the CPU 110. The dedicated hardware unit is, for example, an ASIC (application-specific integrated circuit), an FPGA (field programmable gate array), or a DSP (digital signal processor). The image forming apparatus 100 may have a hardware processor other than a CPU (for example, a GPU) instead of or in addition to the CPU 110. An HDD (hard disk drive) 120 stores, for example, a control program and initial values of various setting values according to the present embodiment. The CPU 110 executes the control program according to the present embodiment read from the HDD 120 to perform the procedures for image formation and the procedure for the steps of each of flowcharts described below. The image forming apparatus 100 may include a nonvolatile storage medium other than the HDD 120 (for example, a ROM (read-only memory) and an SSD (solid-state drive)) in addition to or instead of the HDD 120. The RAM 130 stores a variety of types of information under the control of the CPU 110. According to the present embodiment, the case in which a sheet to be printed is pap
