Service call system

A method of managing a printing device via a network, the method comprising:

• storing information that is transmitted from the printing device;
• receiving a specified notification, wherein the specified notification includes printing device identification information that identifies the printing device;
• extracting information correlating to the printing device identification information from the stored information;
• creating a failure inference information based on the extracted information, wherein the failure inference information indicates a deterioration of printing quality of the printing device,
• creating reply information including the failure inference information in relation to the specified notification based on the extracted information, and
• sending the reply information to a specified transmission destination.

A service call system comprising a printing device and a management system that manages the printing device are connected to a network,

• wherein the printing device comprises:
• a transmission unit that transmits specified information relating to the usage status of the printing device to the management system;
• a detection unit that detects a specified operation in relation to the printing device;
• and
• a notification unit that, when this detection is made, notifies the management system of a specified notification that includes printing device identification information that identifies the printing device;
• and wherein the management system comprises:
• an information storage unit that stores information transmitted from the printing device;
• a receiving unit that receives the specified notification;
• an extraction unit that extracts information correlating to the printer device identification information from the stored information;
• and
• a processing unit that performs a specified process in relation to the specified notification based on the extracted information,
• an inference information creation unit that creates a failure inference information based on the extracted information, wherein the failure inference information indicates a deterioration of printing quality of the printing device,
• a reply creating unit that creates reply information including the failure inference information in relation to the specified notification based on the extracted information, and
• a sending unit that sends the reply information to a specified transmission destination.
