  • Coupling mechanism for a two piece printer cartridge
    Publication number: 20040184834
    Abstract: In a two piece toner cartridge assembly, as typically used in a computer and/or facsimile printing device, comprising separable photoconductor and developer units a unique coupling device is provided whereby the cartridge assembly may be removed from the printing device without the photoconductor unit separating from the developer unit for paper jam clearance or unit replacement. However, if desired the developer unit may be separately removed from the printing device for servicing or replacement without removal of the photoconductor unit.
