摘要:
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 a storage device 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 device thereof and stores the data in a memory 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.

摘要:
A communication control device connected between an image forming apparatus and a communication line in an image forming apparatus supervising system which connects the image forming apparatus and a host machine by the communication line. Assume that particular data of an image forming apparatus which is updated day by day should be read periodically. Then, even when the power supply to the image forming apparatus is shut off, a host machine can access the apparatus to read the data which should be read periodically, and receive it. In addition, the data can be preserved until the next time for reading. The data is stored in a first memory until the data is ready for transfer to the host machine, at which time the data is transferred to a second memory and then to the host machine.

摘要:
In an image forming apparatus, an operating section accessible for entering various information and commands is implemented as a plurality of key units. The key units are each removably connected to the body of the operating section via cooperative connectors. When any one of the key units is damaged or or the life thereof expires, only the defective unit is replaced while the other units are continuously used.
摘要:
An image forming device management system includes a plurality of image forming devices, a central service station which provides a maintenance service for the image forming devices, and a communication control unit which is connected to each of the image forming devices by a signal line, the communication control unit connecting one of the image forming devices to the central service station via a communication network. In the system, each of the image forming devices includes a message unit which outputs a signal line separation message when the image forming device has no signal from the central service station or the communication control unit over a predetermined period.
