Replaceable unit for an electrophotographic image forming device having a magnetic sensor

A replaceable unit for an electrophotographic image forming device, comprising:

• a housing having a top, a bottom, a front and a rear positioned between a first side and a second side of the housing, the housing has a reservoir for holding toner;
• a magnet movably positioned on the housing;
• and
• an electrical connector on the first side of the housing, the electrical connector includes an electrical contact for contacting a corresponding electrical contact in the image forming device, the electrical connector includes a magnetic sensor, the electrical contact of the replaceable unit is electrically connected to the magnetic sensor, the electrical connector is movable between a first position and a second position,
• wherein when the electrical connector moves from the first position to the second position the electrical contact of the replaceable unit moves from a retracted position to an operative position, the electrical contact of the replaceable unit is unobstructed to contact the corresponding electrical contact in the image forming device when the electrical contact of the replaceable unit is in the operative position,
• wherein when the electrical connector moves from the first position to the second position the magnetic sensor moves from a misaligned position to an aligned position with a point in a path of movement of the magnet for sensing a magnetic field of the magnet when the magnet passes the magnetic sensor.

A replaceable unit for an electrophotographic image forming device, comprising:

• a housing having a top, a bottom, a front and a rear positioned between a first side and a second side of the housing, the housing has a reservoir for holding toner;
• an outlet in fluid communication with the reservoir positioned on the front of the housing for exiting toner from the replaceable unit;
• a rotatable shaft positioned in the reservoir;
• a magnet movable in response to rotation of the shaft;
• and
• an electrical connector on the first side of the housing, the electrical connector includes an electrical contact for contacting a corresponding electrical contact in the image forming device, the electrical connector includes a magnetic sensor, the electrical contact of the replaceable unit is electrically connected to the magnetic sensor, the electrical connector is pivotable about a pivot axis between a retracted position and an operative position, the electrical contact of the replaceable unit faces downward and is unobstructed from below when the electrical connector is in the operative position permitting the corresponding electrical contact in the image forming device to contact the electrical contact of the replaceable unit from below, the magnetic sensor faces inward toward the first side of the housing and is aligned with a point in a path of movement of the magnet when the electrical connector is in the operative position for sensing a magnetic field of the magnet when the magnet passes the magnetic sensor.
