A toner cartridge, 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 port in fluid communication with the reservoir and facing downward on the front of the housing near the first side of the housing for exiting toner from the toner cartridge;
• a linkage on the first side of the housing, the linkage has an engagement surface that is accessible from the rear of the housing to receive an actuation force;
• and
• a projection on the first side of the housing, the projection is movable between a first position and a second position, the projection is operatively connected to the linkage such that the actuation force on the linkage causes the projection to move from the first position to the second position to change a state of a sensor in an image forming device that is positioned next to the first side of the housing when the toner cartridge is installed in the image forming device.
