Information processing system, non-transitory computer readable medium, and image forming system

A non-transitory computer readable medium storing a program causing a computer to execute a process comprising:

• if a usage contract period has expired, activating a use-prohibited state that prohibits use of at least some functions of a system;
• outputting, as first printed material, inquiry information containing at least one piece of information from among identification information for the system and identification information for a user who uses the system;
• and
• releasing the use-prohibited state of the system according to use-prohibited state release instruction information outputted in response to the inquiry information outputted as the first printed material.

An image forming system comprising:

• a first image forming apparatus provided with a first communication unit, a first image reading unit, a first image printing unit, and a first processor;
• and
• a second image forming apparatus provided with a second communication unit, a second image reading unit, a second image printing unit, and a second processor, wherein if a usage contract period has expired, the first processor is configured to activate a use-prohibited state that prohibits use of at least some functions of the first image forming apparatus,
• the first processor is configured to output, as first printed material from the first image printing unit, inquiry information containing identification information for the first image forming apparatus,
• the second processor is configured to use the second communication unit to transmit, to a management server that manages usage contract periods, inquiry information acquired by using the second image reading unit to read the first printed material,
• the second processor is configured to output, as second printed material from the second image printing unit, use-prohibited state release instruction information transmitted from the management server in response to the transmitted inquiry information, and
• the first processor is configured to release the use-prohibited state of the first image forming apparatus according to the use-prohibited state release instruction information acquired by using the first image forming unit to read the second printed material.
