Abstract

In an image forming device, a first transmitting unit periodically transmits a regular message, indicating a state information of the device, to a central management equipment by connecting the device to the management equipment via a communication line when a timing of dispatch of the regular message is detected. A second transmitting unit transmits an irregular message, indicating a malfunction information of the device, to the management equipment by connecting the device to the management equipment via the communication line when a malfunction in the device is detected. A transmission judgment unit determines, immediately before the regular message transmission is started, whether the irregular message has been transmitted within a preset period prior to a timing of the regular message transmission, based on a stored newest malfunction information.

Claims

1. An image forming device equipped with a communication unit which connects the image forming device to a central management equipment via a communication line in order to allow the central management equipment to remotely perform maintenance of the image forming device, the image forming device comprising:

a first transmitting unit periodically transmitting a regular message, indicating a state information of the device, to the management equipment by connecting the device to the management equipment via the communication line when a timing of dispatch of the regular message is detected;

a second transmitting unit transmitting an irregular message, indicating a malfunction information of the device, to the management equipment by connecting the device to the management equipment via the communication line when a malfunction in the device is detected; and

a transmission judgment unit determining, immediately before the regular message transmission is started, whether the irregular message has been transmitted within a preset period prior to a timing of the regular message transmission, based on a stored newest malfunction information, the transmission judgment unit allowing the first transmitting unit to transmit the regular message only when it is determined that the irregular message has not been transmitted within the preset period.

2. The image forming device according to claim 1, further comprising a preset period changing unit which changes the preset period of the transmission judgment unit to an arbitrarily selected period in response to a preset period changing command.

3. The image forming device according to claim 1, wherein the first transmitting unit is configured to transmit the regular message to the management equipment when a predetermined date and time of regular message transmission is reached.

4. The image forming device according to claim 1, wherein the first transmitting unit is configured to transmit the regular message to the management equipment when a total number of copy sheets used exceeds a predetermined number.

5. The image forming device according to claim 1, wherein the first transmitting unit is configured to transmit the regular message to the management equipment when a period of use of the image forming device exceeds a predetermined period.

6. The image forming device according to claim 1, further comprising a control operation inhibiting unit which cancels, when a control operation inhibiting command is inputted, the judgment operation of the transmission judgment unit as to whether the regular message transmission is allowed or not.

7. The image forming device according to claim 1, further comprising a malfunction information memory that stores the newest malfunction information which is received from the second transmitting unit as a result of the irregular message transmission, wherein the transmission judgment unit reads the newest malfunction information from said memory before the determination is performed.

8. The image forming device according to claim 1, wherein the transmission judgment unit inhibits the transmission of the regular message by the first transmitting unit when it is determined that the irregular message has been transmitted within the preset period.

9. The image forming device according to claim 1, further comprising a dispatch detecting unit which detects the timing of dispatch of the regular message depending on whether a predetermined date and time of regular message transmission is reached.

10. The image forming device according to claim 1, further comprising a dispatch detecting unit which detects the timing of dispatch of the regular message depending on whether a total number of copy sheets used by the image forming device exceeds a predetermined number.

11. The image forming device according to claim 1, further comprising a dispatch detecting unit which detects the timing of dispatch of the regular message depending on whether a period of use of the image forming device exceeds a predetermined period.
