Patent ID: 8549190

Claim:
An information processing device, to which a peripheral device using a consumable item is connected, comprising: a peripheral device information acquisition unit to acquire peripheral device information including a use amount of the consumable item used on the peripheral device; a cumulative use amount acquisition unit to acquire a cumulative use amount of the consumable item by accumulating the use amount; an event log acquisition unit to acquire an event log including contents of an event that has occurred on the information processing device and an occurrence date/time of the event; a limit value calculation unit to calculate an estimated limit value of the use amount of the consumable item based on the cumulative use amount of the consumable item obtained at the occurrence date/time of the event regarding the event log including the contents regarding the consumable item; a threshold value calculation unit to calculate a threshold value for judging a timing to output a replacement/replenishment prompt notification in comparison with a current cumulative use amount based on a use tendency of the consumable item and the limit value; and a use tendency calculation unit to calculate, as the use tendency of the consumable item, a use amount of the consumable item per unit-time by dividing the cumulative use amount by a use period of the consumable item, and wherein the threshold value calculation unit calculates the threshold value by subtracting, from the limit value, a value obtained by multiplying the use amount of the consumable item per unit-time by a period required for replacement/replenishment of the consumable item.
