Image reading apparatus having error specification and control method of image reading apparatus

An image reading apparatus connectable to an information processing apparatus comprising predetermined software, the image reading apparatus comprising:

• at least a processor and at least a memory coupled to the processor and having stored thereon instructions, wherein the instructions are executed by the processor to act as:
• a reading unit configured to perform scan processing for a document in a case where a read command transmitted from the information processing apparatus by user operation to the predetermined software is received;
• a detection unit configured to detect an error in the image reading apparatus;
• and
• a transmission unit configured to execute image data transmission processing for transmitting image data corresponding to the detected error in a case where the detected error is a first error, and execute error transmission processing different from the image data transmission processing in a case where the detected error is a second error.
