Abstract
Abstract A copying-machine management system for effecting centralized management of a plurality of copying machines in such a manner that data about problems developed during the maintenance of each copying machine is not counted as data about the problem occurring in each copying machine. A control CPU incorporated into a copying machine on the user side is electrically connected to a management CPU on the service station side through a communication line. Thus, a signal indicative of the state of the copying machine on the user side is sent to the management CPU on the service station, where each of the copying machines is managed. When a serviceman is sent to repair the copy machine, a serviceman mode is set. When the serviceman mode is set, the data indicating a problem is prohibited from being transmitted to the management CPU. Therefore, the data about a problem developed due to a reproduction test is not counted as the data about the problem occurring in each copying machine. Thus, since the data developed during the maintenance of each copying machine is not counted, each of the copying machines can be accurately managed.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
106 words
An image forming apparatus connected to an information management apparatus through a communication line, said image forming apparatus including: detecting means for detecting a problem in the image forming apparatus; sending means for sending data indicating an occurrence of the problem to the information management apparatus when the problem is detected by said detecting means; setting means for setting a mode in which the image forming apparatus is in a test operation state to repair the problem; and prohibiting means for prohibiting the data indicating an occurrence of a problem from being sent by said sending means while said mode is set by said setting means.
Claim 2
Dependent Claim
106 words
An image forming apparatus connected to an information management apparatus through a communication line, said image forming apparatus including: detecting means for detecting a problem in the image forming apparatus; sending means for sending data indicating an occurrence of the problem to the information management apparatus when the problem is detected by said detecting means; setting means for setting a mode in which the image forming apparatus is in a test operation state to repair the problem; and prohibiting means for prohibiting the data indicating an occurrence of a problem from being sent by said sending means while said mode is set by said setting means.
Claim 3
Dependent Claim
29 words
The image forming apparatus as claimed in claim 1, wherein said setting means is a card which sets said mode by the insertion thereof into the image forming apparatus.
Claim 4
Dependent Claim
69 words
The image forming apparatus as claimed in claim 1 further comprising a second sending means for sending data concerning the image forming apparatus to the information management apparatus by manual operation thereof and counting means for counting a number of times of the manual operation of said second sending means, wherein said setting means sets said mode when the manual operation of said-second sending means is executed odd-numbered times.
Claim 5
Dependent Claim
32 words
The image forming apparatus as claimed in claim 3, wherein said mode set by said setting means is cancelled when the manual operation of said second sending means is executed even-numbered times.
Claim 6
Dependent Claim
78 words
The image forming apparatus as claimed in claim 1 further comprising second sending means for sending data concerning the image forming apparatus to the information management apparatus by manual operation thereof and timing means for timing a predetermined time, wherein said setting means sets said mode when the manual operation of the second sending means is executed and cancels said mode when the predetermined time is timed by the timing means from the execution of the manual operation.
Claim 7
Dependent Claim
35 words
The image forming apparatus as claimed in claim 1, wherein said setting means includes a mode setting switch and said mode is set by operating the mode setting switch prior to repair of the apparatus.
Claim 8
Dependent Claim
41 words
The image forming apparatus as claimed in claim 1 further comprising inputting means for inputting an identification code, wherein said setting means sets said mode when the identification code is inputted by the inputting means prior to repair of the apparatus.
Claim 9
Dependent Claim
122 words
An image forming apparatus connected to an information management apparatus through a communication line, said image forming apparatus including: detecting means for detecting a problem in the image forming apparatus; first sending means for automatically sending data indicating an occurrence of the problem to the information management apparatus when the problem is detected by said detecting means; second sending means for manually sending data concerning the image forming apparatus to the information management apparatus; timing means for timing a predetermined time; and prohibiting means for prohibiting the data indicating an occurrence of a problem from being sent by said first sending means until the predetermined time is timed by said timing means after the data is sent by said second timing means.
Claim 10
Dependent Claim
122 words
An image forming apparatus connected to an information management apparatus through a communication line, said image forming apparatus including: detecting means for detecting a problem in the image forming apparatus; first sending means for automatically sending data indicating an occurrence of the problem to the information management apparatus when the problem is detected by said detecting means; second sending means for manually sending data concerning the image forming apparatus to the information management apparatus; timing means for timing a predetermined time; and prohibiting means for prohibiting the data indicating an occurrence of a problem from being sent by said first sending means until the predetermined time is timed by said timing means after the data is sent by said second timing means.
Claim 11
Dependent Claim
131 words
A management system for managing maintenance information of an image forming apparatus by an information management apparatus through a communication line, comprising: detecting means for detecting a problem in the image forming apparatus; sending means for sending data indicating an occurrence of the problem to the information management apparatus when the problem is detected by said detecting means; setting means provided for setting a mode in which the image forming apparatus is in a test operation state to repair the problem; counting means for counting the data indicating an occurrence of a problem sent to the information management apparatus unit from said sending means; and prohibiting means for prohibiting said counting means from counting the data indicating an occurrence of a problem while said mode is set by the setting means.
Claim 12
Dependent Claim
131 words
A management system for managing maintenance information of an image forming apparatus by an information management apparatus through a communication line, comprising: detecting means for detecting a problem in the image forming apparatus; sending means for sending data indicating an occurrence of the problem to the information management apparatus when the problem is detected by said detecting means; setting means provided for setting a mode in which the image forming apparatus is in a test operation state to repair the problem; counting means for counting the data indicating an occurrence of a problem sent to the information management apparatus unit from said sending means; and prohibiting means for prohibiting said counting means from counting the data indicating an occurrence of a problem while said mode is set by the setting means.
Claim 13
Dependent Claim
67 words
The management system as claimed in claim 9 further comprising a second sending means for sending data concerning the image forming apparatus to the information management apparatus by manual operation thereof and means for counting a number of times of the manual operation of said second sending means, wherein said setting means sets said mode when the manual operation of said sending means is executed odd-numbered times.
Claim 14
Dependent Claim
