  • Seal for toner cartridge assembly
    Patent number: 6993265
    Abstract: A recharged toner cartridge assembly is disclosed in which a sealing member is provided between the toner hopper and the feed roller compartment to prevent leakage of the recharged toner powder. In particular, the sealing member is fixed to the bottom surface of the feed roller compartment before the compartment is brought to engage with the toner hopper, thus avoiding any inadvertent messing of the toner powder in the toner hopper.
