  • Waste toner solidification apparatus for a printing device
    Patent number: 7778586
    Abstract: A waste toner solidification apparatus for a printing device includes a nozzle configured to receive waste toner from a hopper. A heater is configured to heat the waste toner in a manner sufficient to liquefy the waste toner within the nozzle. Substantially when exiting the nozzle, the liquefied waste toner solidifies and forms a plurality of solid waste toner pellets.

  • Printing device cartridge having position in which rollers are separated from photoconductor
    Patent number: 7221888
    Abstract: A cartridge for a printing device includes first and second portions coupled to one another and capable of moving relative to each other, one or more rollers situated at the first portion, a photoconductor situated at the second portion, and a lock mechanism. The rollers are in contact with the photoconductor in a first position of the first and the second portions. The lock mechanism maintains the first and the second portions in a second position in which the rollers are separated from the photoconductor.

  • System for and method of preventing toner leakage past developer seals using static charge
    Patent number: 6681087
    Abstract: The present invention includes a method of sealing a toner supply to a developer sleeve including the steps of introducing a static-electric charge on toner particles to create charged toner particles and inducing an attractive charge onto each end of the developer sleeve. The static-electric charge and the attractive charge result in toner particles being attracted to the ends of the developer sleeve which create a barrier of charged toner particles to prevent leakage of the charged toner particles.
