Image forming apparatus and method for controlling image forming apparatus

An image forming apparatus comprising:

• a plurality of feeding decks each containing a recording sheet;
• a display unit configured to display information;
• an image forming unit configured to form an image on the recording sheet conveyed from one of the plurality of feeding decks, the image forming unit including a plurality of parts;
• a scanning unit configured to scan the image formed by the image forming unit;
• one or more processors and one or more memories cooperating to:
• perform control to display information about the plurality of feeding decks on the display unit,
• obtain information about a recording sheet contained in each of the plurality of feeding decks, and
• determine a feeding deck containing a recording sheet appropriate for determination of a defective part in the image forming unit among the plurality of feeding decks based on the obtained information about the recording sheet;
• and
• a diagnosis unit configured to diagnose the defective part in the image forming unit based on the image formed on the recording sheet by the image forming unit, the recording sheet being conveyed from the determined feeding deck, the image being obtained by scanning by the scanning unit.

A method for controlling an image forming apparatus, the image forming apparatus including a plurality of feeding decks each containing a recording sheet, a display unit configured to display information, an image forming unit configured to form an image on the recording sheet conveyed from one of the plurality of feeding decks, the image forming unit including a plurality of parts, and a scanning unit configured to scan the image formed by the image forming unit, the method comprising:
