Remote control method of a facsimile device

Abstract

A method for interactively diagnosing and controlling a state of a remote facsimile device which communicates with a center facsimile device of an after-service center by using non-standard format by writing or reading data into or from memory includes the steps of: requesting entry of a telephone number of the remote facsimile device after determining a remote control mode exists when a function key is pressed; checking whether a memory reading or writing mode is selected and determining whether a remote diagnosis process, a name registration process, a telephone number registration process and an option reading process are selected. When the above processes are selected respectively, each process is performed and results are printed. If, however, the option reading process was not selected, the method proceeds to a memory reading process for repeatedly performing the foregoing steps.
