Abstract
A waste toner removal system for an image forming device. The invention includes a mechanism for removing the waste toner from the cartridge and transporting it through a toner chute to a waste toner tank. One or more actuators within the device allow for the connection between the various elements to seal the waste toner path and prevent toner leakage. Methods of moving waste toner are also disclosed that include moving the waste toner through the cartridge and into a waste toner chute. The waste toner is moved through the chute and into a waste toner tank where it may be removed from the device.
