Abstract: A toner cartridge according to one example embodiment includes a housing having a toner reservoir. An outlet port faces downward on a front of the housing near a first side of the housing. A linkage is positioned on the first side of the housing and has an engagement surface that is accessible at the rear of the housing. A projection is positioned on the first side of the housing and is movable between a first position and a second position. The projection is operatively connected to the linkage such that the projection moves upward from the first position to the second position when the engagement surface receives a forward force that is toward the front of the housing. The projection extends outward sideways from the first side when the projection is in the second position.

Abstract: A replaceable unit for an electrophotographic image forming device according to one example embodiment includes a housing having a reservoir for storing toner. A rotatable shaft is positioned within the reservoir and has an axis of rotation. A first magnet and a second magnet are connected to the shaft and rotatable around the axis of rotation in response to rotation of the shaft. The first magnet and the second magnet pass near at least a portion of an inner wall of the housing forming the reservoir during rotation of the first and second magnets. An amount of angular offset between the first magnet and the second magnet varies depending on an amount of toner in the reservoir.

Abstract: A toner cartridge according to one example embodiment includes a housing having a toner reservoir. An outlet port faces downward on a front of the housing near a first side of the housing. A shutter is movable between a closed position blocking the outlet port and an open position unblocking the outlet port. A flag on the first side of the housing is movable between a first position and a second position. The flag extends outward sideways from the first side when the flag is in the second position. The flag is operatively connected to the shutter such that when the shutter moves from the closed position to the open position the flag moves from the first position to the second position to change a state of a sensor in the image forming device when the toner cartridge is installed in the image forming device.

Abstract: A replaceable unit for an electrophotographic image forming device according to one example embodiment includes a housing having a reservoir for storing toner. A rotatable shaft is positioned within the reservoir and has an axis of rotation. A first magnet and a second magnet are connected to the shaft and rotatable around the axis of rotation in response to rotation of the shaft. The first magnet and the second magnet are detectable by a magnetic sensor when the replaceable unit is installed in the image forming device. A polarity of the first magnet is oriented opposite a polarity of the second magnet relative to the shaft. An amount of angular offset between the first magnet and the second magnet varies depending on an amount of toner in the reservoir.

Abstract: An electrophotographic image forming device according to one example embodiment includes a replaceable unit having a reservoir for storing toner and a rotatable shaft positioned within the reservoir. The replaceable unit has a first magnet and a second magnet connected to the shaft and rotatable around an axis of rotation of the shaft in response to rotation of the shaft. An amount of angular offset between the first magnet and the second magnet varies depending on an amount of toner in the reservoir. A sensor is positioned to sense the first magnet and the second magnet at a point in their rotational paths. A processor is in electronic communication with the sensor and configured to determine an angular offset between the first magnet and the second magnet and to adjust an estimate of the amount of toner remaining in the reservoir based on the determined angular.
