Image forming apparatus, control method for image forming apparatus, and non-transitory computer-readable storage medium

An image forming apparatus comprising:

• a sheet support portion configured to support a sheet;
• a size detection unit configured to detect a size of a sheet supported on the sheet support portion;
• a user interface configured to be inputted a size and a type of a sheet supported on the sheet support portion and to display an image;
• and
• a control unit configured to control the user interface such that
• if the control unit acquires a detection result of a size of a sheet supported on the sheet support portion by the size detection unit in a state where a size and a type of a sheet supported on the sheet support portion has been inputted through the user interface, and
• if a combination of the type of the sheet having been inputted through the user interface and the detection result of the size of the sheet detect by the size detection unit corresponds to a predetermined prohibited combination,
• the user interface displays a set screen on which a type of a sheet supported on the sheet support portion is inputted,
• wherein the control unit is implemented by one or more processor.

• the user interface displays an image making a notification that a setting of a type of a sheet has been changed in accordance with a predetermined rule,
• wherein the control unit is implemented by one or more processor.

A control method for an image forming apparatus comprising:

• storing a first information related to a size of a sheet supported on a sheet support portion into a storage portion;
• storing a second information related to a type of a sheet supported on the sheet support portion into the storage portion;
• and
• determining whether a detection result of a size of a sheet supported on the sheet support portion satisfies a predetermined combination condition with respect to the second information stored in the storage portion, the determining step being executed if a size of a sheet supported on the sheet support portion is detected by a size detection unit in a state where the first information and the second information that satisfy a predetermined combination condition is stored in the storage portion.
