Scanner, scanning system, and non-transitory computer-readable recording medium for scanner

A non-transitory computer-readable recording medium for a scanner provided with a scanning engine configured to scan an image on an original document and generate scan data representing the image on the original document, a memory, a user interface provided with an operation key, and a controller, the recording medium containing computer-executable instructions which cause, when executed by the controller, the scanner to perform:

• storing destination information in the memory, the destination information corresponding to a destination to which the scan data is to be transmitted;
• determining whether the destination information is stored in the memory;
• when it is determined, in the determining, that the destination information is not stored in the memory, disabling the operation key;
• when it is determined, in the determining, that the destination information is stored in the memory, enabling the operation key;
• and
• when the enabled operation key is operated in a state where the operation key is enabled, transmitting the scan data as generated to the destination indicated by the destination information.

A scanning system comprising a server and a scanner,

• wherein the server comprises a first memory that stores destination information corresponding to a destination to which the scan data is to be transmitted, a first communication interface, and a first controller,
• wherein the first controller is configured to perform:
• receiving an instruction to add or delete the destination information to or from a terminal,
• updating the destination information stored in the first memory in accordance with the instruction as received, and
• transmitting the updated destination information to the scanner via the first communication interface,
• wherein the scanner comprises a second communication interface, a second memory, a second controller, and a user interface having an operation key, and
• wherein the second controller is configured to perform:
• receiving the updated destination information from the server;
• storing the updated destination information in the second memory;
• determining whether the destination information is stored in the second memory;
• disabling the operation key when determining that the destination information is not stored in the second memory in the determining;
• enabling the operation key when determining that the destination information is stored in the second memory in the determining;
• and
• transmitting the generated scan data to a destination indicated by the destination information when the enabled operation key is operated.
