Method and apparatus for a connection sensing apparatus

1. A system comprising:

a device; and

an apparatus for connecting a transmission line to the device, the transmission line having a connector at one end of the transmission line, the apparatus being part of, or being connected to the device, the apparatus including:

(a) a receptacle for receiving the connector; and

(b) a sensor associated with the receptacle for detecting the presence of the connector within the receptacle;

the device including:

a controller that determines whether a signal indicating availability of the transmission line has been detected, wherein, when the controller determines that the signal indicating availability of the transmission line has not been detected, the controller issues an inquiry as to whether the presence of the connector within the receptacle has been detected by the sensor.

2. The system of claim 1 , wherein the signal indicating availability of the transmission line is a telephone dial tone.

3. The system of claim 1 , wherein, in response to a signal from the sensor indicating that the connector is present within the receptacle, the controller determines whether signals are being communicated through the transmission line.

4. The system of claim 1 , wherein the controller controls the sensor to determine whether the connector is present within the receptacle when the device is activated.

5. The system of claim 1 , wherein the controller determines, at times other than on device activation, whether signals are being communicated through the transmission line.

6. The system of claim 1 , wherein the device further comprises a control panel that displays the inquiry issued from the controller.

7. The system of claim 6 , wherein the control panel displays a message indicating that no signals communicated through the transmission line have been detected, and suggesting inspection of physical connection of the connector within the receptacle.

8. A system comprising:

a device; and

an apparatus for connecting a transmission line to the device, the transmission line having a connector at one end of the transmission line, the apparatus being part of, or being connected to the device, the apparatus including:

(a) a receptacle for receiving the connector; and

(b) a sensor associated with the receptacle for detecting the presence of the connector within the receptacle;

the device including:

a controller that determines whether a signal indicating availability of the transmission line has been detected, wherein, when the controller determines that the signal indicating availability of the transmission line has not been detected, the controller issues an inquiry as to whether the presence of the connector within the receptacle has been detected by the sensor,

wherein the sensor comprises a pressure switch within the receptacle.

9. The system of claim 8 , wherein the device further comprises a control panel that displays the inquiry issued from the controller.

10. The system of claim 9 , wherein the control panel displays a message indicating that no signals communicated through the transmission line have been detected, and suggesting inspection of physical connection of the connector within the receptacle.

11. A system comprising:

a device; and

an apparatus for connecting a transmission line to the device, the transmission line having a connector at one end of the transmission line, the apparatus being part of, or being connected to the device, the apparatus including:

(a) a receptacle for receiving the connector; and

(b) a sensor associated with the receptacle for detecting the presence of the connector within the receptacle, wherein the sensor comprises an optical sensor within the receptacle,

the optical sensor comprising:

a light emitting device;

a light sensor; and

a mirror,

wherein:

when the connector is not present within the receptacle, the light sensor receives the light emitted from the light emitting device that has been reflected by the mirror; and

when the connector is present with in the receptacle, the connector blocks light passages between the light emitting device and the mirror, and between the mirror and the light sensor,

the device including:

a controller that determines whether a signal indicating availability of the transmission line has been detected, wherein, when the controller determines that the signal indicating availability of the transmission line has not been detected, the controller issues an inquiry as to whether the presence of the connector within the receptacle has been detected by the sensor.

12. A printing machine capable of communicating with a network through a transmission line, the transmission line having a connector at one end of the transmission line, the printing machine comprising:

(a) a receptacle for receiving the connector;

(b) a sensor associated with the receptacle for detecting the presence of the connector within the receptacle;

(c) a sensor circuit, communicating with the detecting sensor, for transmitting a signal indicating whether the detecting sensor detects the presence of the connector; and

(d) a controller that determines whether a signal indicating availability of the transmission line has been detected, wherein, when the controller determines that the signal indicating availability of the transmission line has not been detected by the signal detector, the controller issues an inquiry as to whether the presence of the connector within the receptacle has been detected by the sensor.

13. The printing machine of claim 12 , further comprising a control panel that displays the inquiry issued from the controller.

14. The printing machine of claim 13 , wherein the control panel displays a message indicating that no signals communicated through the transmission line have been detected, and suggesting inspection of physical connection of the connector within the receptacle.
