First Claim
Patent Images
1. A monitor system for monitoring a state of an image forming device, comprising:
- detector means for detecting the state of the image forming device; and
transmitter means for transmitting status data representing the state to a monitor device upon a state change being detected by said detector means, said transmitter means including holding means for holding the status data in accordance with a failure of transmission of the status data, wherein said transmitter means transmits the status data held by said holding means in accordance with a new state change detected by said detector means.

Abstract
A monitor system comprises a detector unit for detecting the state of an image forming device, and a transmitter unit for transmitting the status data representing the state to a monitor device upon a state change being detected by the detector unit. If the transmitter unit fails to transmit the status data, it stores the status data and transmits the status data stored upon the new state change being detected by the detector unit. This allows for the secure transmission of the status data of the image forming device which has not been transmitted to the monitor device due to a temporary malfunction of the line.
