Abstract
In the host computer of a multiple photocopier management system, a maintenance supervising system is provided for supervising maintenance job contents on routinely serviced photocopier components. Stored in the host computer RAM are maintenance tables for retaining in routine maintenance sequences job items for periodic maintenance on the photocopier components. After completing routine maintenance on a photocopier, a service engineer inputs maintenance reporting data which is accepted in job store areas of the RAM. The maintenance reporting data categorizes a maintenance job, in particular as to whether a component has been repaired, and indicates actual job content, component-by-component. The routine maintenance sequences each constitute an order of ranking numbers each assigned to a job item, and the rank order in the sequence is updated according to the ranking number corresponding to the content of the reported job. Based on the maintenance reporting data accepted by the RAM, and on the updated job rank orders in the routine maintenance sequences, the host computer sets job items component-by-component for the next-scheduled routine maintenance from the job items stored in t…
