Image reading apparatus having sensor for detecting shape of fed documents, control method for controlling image reading apparatus, and storage medium having stored therein control method

A control method for an image processing apparatus, the control method comprising:

• reading an image on a document sheet conveyed by a conveyor, the conveyor including a separation portion configured to separate the document sheet from a plurality of document sheets, a sensor being provided on an upstream side of the separation portion in a conveyance direction by the conveyor, the sensor detecting a position in a height direction of the document sheet conveyed by the conveyor;
• performing a function for causing, if the position in the height direction of the document sheet detected by the sensor reaches an abnormal position, the conveyor to stop conveyance of the document sheet;
• and
• displaying, on a condition that the position in the height direction of the document sheet detected by the sensor reaches the abnormal position, information recommending that a user disables the function.

A non-transitory computer readable storage medium for storing a computer program for causing an image processing apparatus to execute a method, the method comprising:

• reading an image on a document sheet conveyed by a conveyor, the conveyor including a separation portion configured to separate the document sheet from a plurality of document sheets, a sensor being provided on an upstream side of the separation portion in a conveyance direction by the conveyor, the sensor detecting a position in a height direction of the document sheet conveyed by the conveyor;
• performing a function for causing, if the position in the height direction of the document sheet detected by the sensor reaches an abnormal position, the conveyor to stop conveyance of the document sheet;
• and
• displaying, on a condition that the position in the height direction of the document sheet detected by the sensor reaches the abnormal position, information recommending that a user disables the function.

An image processing apparatus comprising:

• a reader;
• a controller configured to perform, in accordance with operation of a start key, a copy job for reading an image on a document sheet conveyed by a conveyor from a plurality of document sheets placed on a document sheet placement unit and printing the image;
• a conveyance controller configured to cause, if stapled document sheets placed on the document sheet placement unit are conveyed, the conveyor to stop conveyance of the document sheets;
• and
• a display configured to display, if the stapled document sheets placed on the document sheet placement unit are conveyed, information for recommending that a user operates the start key after the document sheets are returned.
