Abstract

A system for an image forming device includes a first replaceable unit including a first electrical connector and a second replaceable unit including a second electrical connector. An electrical connector in the image forming device is movable between a disengaged position and an engaged position. In the disengaged position the electrical connector in the image forming device is disengaged from the first electrical connector of the first replaceable unit and the second electrical connector of the second replaceable unit when the first and second replaceable units are installed in the image forming device. In the engaged position the electrical connector in the image forming device is engaged with the first electrical connector of the first replaceable unit and the second electrical connector of the second replaceable unit when the first and second replaceable units are installed in the image forming device.

5. The system of claim 4 , wherein the first electrical contact of the electrical connector in the image forming device has a first contact surface that engages the first corresponding electrical contact of the first electrical connector of the first replaceable unit and the second electrical contact of the electrical connector in the image forming device has a second contact surface that engages the second corresponding electrical contact of the second electrical connector of the second replaceable unit when the electrical connector in the image forming device is in the extended position and the first and second replaceable units are installed in the image forming device, the first contact surface of the first electrical contact and the second contact surface of the second electrical contact face away from each other.

6. The system of claim 4 , wherein the first and second electrical contacts of the electrical connector in the image forming device are electrically connected to each other.

7. The system of claim 4 , wherein the first and second electrical contacts of the electrical connector in the image forming device move away from each other when the electrical connector in the image forming device moves from the disengaged position to the engaged position.

8. The system of claim 4 , wherein the first and second electrical contacts of the electrical connector in the image forming device move toward each other when the electrical connector in the image forming device moves from the engaged position to the disengaged position.

9. A system for an electrophotographic image forming device, comprising;

a first replaceable unit and a second replaceable unit matable with the first replaceable unit, the first replaceable unit includes a reservoir for storing toner and the second replaceable unit is configured to receive toner from the first replaceable unit when the first and second replaceable units are mated, the first and second replaceable units are removably installable in the image forming device;

a first electrical connector on the first replaceable unit and a second electrical connector on the second replaceable unit, the first electrical connector and the second electrical connector are spaced from each other such that a gap exists between the first electrical connector and the second electrical connector when the first and second replaceable units are mated; and

an electrical connector mounted in the image forming device, the electrical connector in the image forming device is movable between an engaged position and a disengaged position, in the engaged position the electrical connector in the image forming device is positioned within the gap such that electrical contacts of the electrical connector in the image forming device contact corresponding electrical contacts of the first and second electrical connectors when the first and second replaceable units are installed in the image forming device, in the disengaged position the electrical connector in the image forming device is removed from the gap such that the electrical contacts of the electrical connector in the image forming device are disengaged from the corresponding electrical contacts of the first and second electrical connectors when the first and second replaceable units are installed in the image forming device.

10. The system of claim 9 , wherein the electrical connector in the image forming device includes a first electrical contact and a second electrical contact, the first electrical contact of the electrical connector in the image forming device contacts a first corresponding electrical contact of the first electrical connector of the first replaceable unit and the second electrical contact of the electrical connector in the image forming device contacts a second corresponding electrical contact of the second electrical connector of the second replaceable unit when the electrical connector in the image forming device is in the engaged position and the first and second replaceable units are installed in the image forming device.

11. The system of claim 10 , wherein the first and second electrical contacts of the electrical connector in the image forming device are electrically connected to each other.

12. The system of claim 10 , wherein the first and second electrical contacts of the electrical connector in the image forming device move away from each other when the electrical connector in the image forming device moves from the disengaged position to the engaged position.

13. The system of claim 10 , wherein the first and second electrical contacts of the electrical connector in the image forming device move toward each other when the electrical connector in the image forming device moves from the engaged position to the disengaged position.

14.
