Abstract

An office machine monitoring device (31) includes an interface unit (32) that couples to a main logic board (50) and a front panel display circuit (52) of an office machine (30). The interface unit (32) intercepts data exchanged between the main logic board (50) and the front panel display circuit (52). The interface unit (32) provides the intercepted data to a microcontroller unit (34) for processing. The microcontroller unit (34) processes the intercepted data and provides a wireless message to a transceiver unit (36). The transceiver unit (36) transmits the wireless message to a supervisory transceiver base unit (28) to allow for remote monitoring and control of the office machine (30).

Claims

1. A device for monitoring an office machine, comprising:

an interface unit coupled to a main logic board and a display circuit of the office machine, the interface unit being directly connected to the main logic board to receive data generated by the main logic board, the interface unit providing the data to the display circuit;

a microcontroller unit operable to process the data provided by the interface unit; and

a transceiver unit operable to transmit the data processed by the microcontroller unit through a wireless transmission technique.

2. The device of claim 1, wherein the interface unit intercepts the data without affecting communications between the main logic board and the display circuit.

3. The device of claim 1, wherein the interface unit connects to a display connection of the main logic board and couples to a logic board connection of the display circuit through a display cable.

4. The device of claim 1, wherein the interface unit is inserted between the display connection of the main logic board and an existing display cable of the office machine extending to the display circuit.

5. The device of claim 1, wherein the office machine is a laser printer.

6. The device of claim 1, wherein the transceiver unit operates at a frequency of 913.5 MHz.

7. A system for monitoring an office machine, comprising:

an office machine monitoring device coupled to the office machine, the office machine monitoring device including;

an interface unit coupled to a main logic board and a display circuit of the office machine, the interface unit being directly connected to the main logic board to receive data generated by the main logic board, the interface unit providing the data to the display circuit;

a microcontroller unit operable to process the data received by the interface unit;

a transceiver unit operable to transmit the data processed by the microcontroller unit through a wireless transmission technique;

a supervisory transceiver base unit operable to receive the data transmitted by the transmitter unit; and

a base microprocessor unit operable to process the data received by the supervisory transceiver base unit.

8. The system of claim 7, further comprising:

a monitoring computer operable to record the data processed by the base microprocessor unit.

9. The system of claim 8, wherein the microprocessor unit sends processed data to the monitoring computer through a DTMF to ASCII converter.

10. The system of claim 8, wherein the monitoring computer is operable to generate control messages for transmission to the office machine, the control messages providing operational instructions for the office machine.

11. The system of claim 7, wherein the office machine is a laser printer.

12. The system of claim 7, wherein the transceiver unit and the supervisory transceiver base unit exchange messages at a frequency of 913.5 MHz.
