Image processing apparatus, and function executed method and function executed program in the apparatus

A function execution method implemented in an image processing apparatus, the method comprising the steps of:

• a) identifying a user of the image processing apparatus;
• b) determining whether settings required for using a function of the image processing apparatus are registered in a user registration unit when a user issues an instruction to execute the function, the settings being related to the user having issued the instruction to execute the function, the user registration unit being capable of registering settings for each user with respect to setting items including items required for using the function and arbitrary items;
• c) executing the function when it is determined that the settings required for using the function are registered in step b);
• and
• d) performing a predetermined operation other than execution of the function when it is determined that the settings required for using the function are not registered in step b).

A non-transitory recording medium storing a computer readable function execution program to be executed by a computer of an image processing apparatus,

• the program causing the computer to carry out the steps of:
• a) identifying a user of the image processing apparatus;
• b) determining whether settings required for using a function of the image processing apparatus are registered in a user registration unit when a user issues an instruction to execute the function, the settings being related to the user having issued the instruction to execute the function, the user registration unit being capable of registering settings for each user with respect to setting items including items required for using the function and arbitrary items;
• c) executing the function when it is determined that the settings required for using the function are registered in step b);
• and
• d) performing a predetermined operation other than execution of the function when it is determined that the settings required for using the function are not registered in step b).
