Problems solved by technology
If the toner cartridge is misaligned, the discharge port on the toner cartridge may not seal the port that receives toner from the cartridge, potentially causing a serious toner leak that can lead to mechanical and print quality defects
Also, if the toner cartridge is misaligned, the drive gear on the toner cartridge may not achieve proper gear engagement with the corresponding drive gear in the image forming device, potentially causing gear cogging

A replaceable unit for an electrophotographic image forming apparatus according to an example embodiment includes an elongate body extending along a longitudinal dimension and having a reservoir for holding toner. The latch catch on the main body is positioned to receive a corresponding latch to restrict forward movement of the main body along the longitudinal dimension when the replaceable unit is installed in the image forming apparatus. A latch actuator at the front of the body is movable relative to the body between a home position and a release position. A release handle at the front of the body provides unobstructed grip for the user and is operatively connected to the latch actuator such that actuation of the release handle causes the latch actuator to move from the home position to the release position to The subject is unlocked from the image forming apparatus.
Description
technical field [0001] The present disclosure relates generally to image forming apparatuses, and more particularly to replaceable units for electrophotographic image forming apparatuses having a latch mechanism. Background technique [0002] To reduce premature replacement of components traditionally housed in toner cartridges for image forming apparatuses, toner cartridge manufacturers have begun to separate longer-lived components from shorter-lived components into separate replaceable units. Relatively long-lived components are located in a replaceable unit (imaging unit). The toner supply of the image forming apparatus, which is consumed relatively quickly compared to the components housed in the imaging unit, is provided in a reservoir in a separate replaceable unit in the form of a toner cartridge which supplies toner to the imaging unit . In this configuration, the number of parts housed in the toner cartridge is reduced as compared with conventional toner cartridg...
