Abstract

In a system in which a host computer performs lifetime management for components of a plurality of copiers, components whose lifetimes are to be managed can be freely selected copier by copier and, as a result, warning reports can be transmitted with a reduced number of communication sessions. The copiers are each equipped with a device for management, so that counting can be performed for their individual components and interlock counts for such counting can be freely specified. The host computer compares a count received through communication with a threshold value to issue a report within the host computer. Within one copier, during a period after a component PM call is issued and before a component is replaced, even if another component becomes a target of a component PM call, the component PM call is not issued. When a component replacement report is received, a report of a component PM call is automatically deleted from an urgency report list. A component whose component PM call has been exceeded is indicated with a mark requesting replacement.
