  • Patent number: 10197944
    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.

  • Publication number: 20180246439
    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.

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.

  • Patent number: 9709928
    Abstract: An intermediate transfer member (ITM) module including a frame; a backup roll and a drive roll rotatably disposed along a first end portion of the frame. A tension roll is rotatably disposed along a second end portion of the frame. An ITM belt forms an endless loop around the backup roll, the drive roll and the tension roll such that rotation of the drive roll causes the ITM belt to translate and the tension roll and the backup roll to rotate. The drive roll and the backup roll form a transfer nip with a transfer roll. A drive mechanism is coupled between the drive roll and the backup roll and includes a plurality of gears. The drive mechanism overdrives the backup roll relative to the drive roll while limiting an amount of tension of the ITM belt in the second transfer nip.

  • Patent number: 9709925
    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.
