ABSTRACT:
In a copier, to execute renewal of a maintenance contract with ease and without fail, a current date is compared with a contract expiry date, and a current total count of copies is compared with a count prescribed by the contract. As long as the contract is valid, the copier is operated in a normal copying mode. Meanwhile, the difference between the current count and the contract count is monitored every time a copying operation takes place. When the contract count is exceeded, the copier displays a message indicating expiry of the contract and requesting renewal of the contract in order to notify its user that the contract count has been exceeded. The copier then switches to a restricted copying operation mode. If the user chooses to renew the contract, the user contacts a service provider, so that the service provider checks the state of the contract for the copier and performs a procedure for renewing the contract.
