Abstract
Abstract A control system for collectively supervising a plurality of copiers or similar image forming apparatuses connected to a control device by communication lines with or without the intermediary of communication control units. To down-load data relating to image formation, the control device determines whether or not a copier of interest is an inoperative state and, if it is in an inoperative state, automatically sends the data to the copier via a telephone line, an exchange, and a communication control unit. This data is written to storing means built in the copier. To up-load data relating to image formation, the control device causes each copier to automatically send the data stored in the storing means thereof and stores the data in memory means thereof. Up-loading is effected at an optimal time other than the time when the copier is performing an automatic adjustment, in use, or quite likely to be used.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
129 words
A system for controlling image formation, comprising: a plurality of image forming apparatuses each having a storage device containing data; a communication control unit connected to said plurality of image forming apparatuses; a control device connected to said communication control unit over a communication line, said control device interchanging said data stored in said storage devices with said image forming apparatuses; said communication control unit further including a parameter storing device having an interchanging control parameter outputting said data and outputting a signal designating any one of said image forming apparatuses to be connected to said communication control unit; and communication control device receiving and sending communication between said designated image forming apparatus and said control device on the basis of the parameter stored in said parameter storing device.
Claim 2
Independent Claim
129 words
A system for controlling image formation, comprising: a plurality of image forming apparatuses each having a storage device containing data; a communication control unit connected to said plurality of image forming apparatuses; a control device connected to said communication control unit over a communication line, said control device interchanging said data stored in said storage devices with said image forming apparatuses; said communication control unit further including a parameter storing device having an interchanging control parameter outputting said data and outputting a signal designating any one of said image forming apparatuses to be connected to said communication control unit; and communication control device receiving and sending communication between said designated image forming apparatus and said control device on the basis of the parameter stored in said parameter storing device.
Claim 3
Dependent Claim
26 words
A system as claimed in claim 1, wherein said parameter is written to said parameter storing device from said control device via a public telephone network.
Claim 4
Dependent Claim
33 words
A system as claimed in claim 1, further comprising a parameter setting device removably mounted to said communication control unit and allowing the parameter to be written to said parameter storing device thereon.
Claim 5
Dependent Claim
40 words
A system as claimed in claim 1, wherein interchange of data between said control device and said communication control unit and interchange of said data between said communication control device and said image forming apparatuses are independent of each other.
Claim 6
Dependent Claim
18 words
A system as claimed in claim 4, wherein said communication control unit comprises a memory containing said data.
Claim 7
Dependent Claim
23 words
A system as claimed in claim 5, wherein said control device reads said data out of said memory of said communication control unit.
Claim 8
Dependent Claim
45 words
A system as claimed in claim 5, wherein said control device sends data, including a parameter designating any one of said image forming apparatuses, to said communication control device, while said communication control device accesses said designated one image forming apparatus designated by said parameter.
Claim 9
Dependent Claim
23 words
A system as claimed in claim 1, wherein the parameter stored in said parameter storing device is a number of times of redialing.
Claim 10
Dependent Claim
29 words
A system as claimed in claim 1, wherein the parameter stored in said parameter storing device determine whether or not said data should be sent to said control device.
Claim 11
Dependent Claim
14 words
A system as claimed in claim 1, wherein said image forming apparatuses are copiers.
