A scan processing system is provided that includes a processor configured to execute a program stored in a memory to implement processes of accepting, from a terminal apparatus, a registration of a scan setting for a scan process to be executed by the input/output device; issuing code information for the scan setting and sending the issued code information to the terminal apparatus in response to the registration of the scan setting; storing the scan setting that has been accepted from the terminal apparatus in association with the code information that has been sent to the terminal apparatus in response to the registration; and upon receiving the code information from the input/output device, sending the scan setting that is stored in association with the code information to the input/output device and controlling the input/output device to execute the scan process based on the scan setting.

An image reading apparatus is configured to: control a scanner unit to optically scans a document and generate scanned data; provide an input screen for allowing a user to input format information defining a particular file format of transmission data that contains the scanned data, wherein the format information includes additional information and wherein the input screen includes a first field for inputting item name of the additional information to be included in the transmission data and a second field for inputting a value of the additional information corresponding to the item name of the additional information; receive the format information input by the user; generate the transmission data, wherein the generated transmission data contains the scanned data and has the format according to the format information received in the receiving processing; and transmit the transmission data to the server through the communication interface.

An example image forming apparatus includes a scan unit to output digital image data of a scanned document, a user interface unit to receive an input of a first destination and a second destination for sending the scanned document, a processor to generate a first file having a first size based on the digital image data, and to generate a second file having a second size, the second size being smaller than the first size, based on the digital image data, a storage unit to store the first file and the second file, and a communication unit to transmit the first file to the first destination and the second file to the second destination.
