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.

A toner cartridge according to one embodiment includes a housing having a toner reservoir. An outlet port in fluid communication with the reservoir is positioned on a front of the housing near a first side of the housing. An interface gear is exposed on the front of the housing near a second side of the housing. A magnet is movable in response to rotation of the interface gear. An engagement member is positioned on an exterior of the top of the housing proximate the second side of the housing. The engagement member is aligned with a point in a path of movement of the magnet. The engagement member has a front surface that is unobstructed to contact and push a magnetic sensor in the image forming device to an operating position of the magnetic sensor during insertion of the toner cartridge into the image forming device.

A method for manufacturing a Z-directed component for insertion into a mounting hole in a printed circuit board according to one example embodiment includes simultaneously extruding a plurality of materials according to the structure of the Z-directed component to form an extruded object and forming the Z-directed component from the extruded object. In one embodiment, the extruded object is divided into individual Z-directed components. In one embodiment, the timing of extrusion between predetermined sections of one of the materials is varied in order to stagger the sections in the extruded object.

A replaceable unit for an electrophotographic image forming device with a housing having a top, a bottom, a front, and a rear positioned between a first side and a second side of the housing as well as a a reservoir for holding toner and a side-to-side dimension that runs from the first side to the second side. An electrical contact is positioned within a pocket on the first side of the housing, with the pocket permitting an electrical connector of the image forming device to enter the pocket and mate with the electrical contact when the replaceable unit is installed in the image forming device. A first guide wall and a second guide wall are each positioned outside the pocket with each including an inclined surface to move the electrical connector of the image forming device along the side-to-side dimension toward the electrical contact during insertion of the replaceable unit into the image forming device.

A sheet processing apparatus includes a punch mechanism disposed along a media path at a punch point at which a hole is to be punched through a punch location on a media sheet advancing along the media path. The punch mechanism includes a rotatable punch arm having a punch head, and a punch motor for rotating the punch arm. As the punch location on the advancing media sheet approaches the punch point, speed of the punch motor is controlled to adjust a rotational speed of the punch arm based on feedback signals associated with each of the punch motor and a media path motor used to advance the media sheet such that the punch head arrives at the punch point at substantially the same time as when the punch location on the media sheet arrives at the punch point.

A method for estimating an amount of toner remaining in a reservoir of a replaceable unit for an image forming device according to one example embodiment includes receiving by processing circuitry pulses from a magnetic sensor. Each pulse is indicative that the magnetic sensor detected a magnet on a moving paddle positioned in the reservoir. The processing circuitry counts the number of the pulses received from the magnetic sensor. Upon receiving a request from a controller of the image forming device, the processing circuitry sends to the controller of the image forming device the count of the pulses received from the magnetic sensor and resets the count of the pulses received from the magnetic sensor.
