  • Patent number: 8938186
    Abstract: A method for aligning a photoconductor cartridge (200) in an electrophotographic device includes providing at least two holes in a first end of the cartridge. At least two pins (251) are provided in a frame of the electrophotographic device which mate with the holes in the first end of the cartridge when the cartridge is inserted in the electrophotographic device. A drive mechanism contacts a spherical bearing of a photoconductor of the cartridge and drives a pair of drive dogs. One drive dog is affixed to a spline on the drive mechanism and a second drive dog is affixed to the spherical bearing. At least one hole is provided in a second end of the cartridge. At least one pin is provided in a frame of the electrophotographic device which mate with the hole in the second end of the cartridge when the cartridge is inserted in the electrophotographic device.

  • Patent number: 8401454
    Abstract: A system for collecting waste toner or developer in an electrophotographic printer includes a waste collection tube for collecting waste toner or developer in an electrophotographic module. An auger transports waste toner or developer from the collection tube through a transport tube to a waste container. A spring has a first end in the collection tube and a second end fixed within the transport tube of the auger. An elbow of the spring rides on the auger and the motion of the auger causes the spring to oscillate in the collection tube.

  • Patent number: 8301061
    Abstract: The adjustment method aligns printing engines in a print assembly that is capable of printing on a receiver to form one or more final prints and includes corrections for cross-track misregistration. These adjustments are made in one embodiment by aligning two or more printing engines in an x and y direction relative to a paper path cross track reference and then aligning each printing engines in a cross track direction (z direction) relative to the paper path cross track reference based on measurements in the cross track direction (z direction) relative to the paper path cross track reference.

  • Patent number: 8139981
    Abstract: A cleaning station for removing particulate material from a moving web in an electrographic printer/copier includes a customer-replaceable web-cleaner device with a support bracket/backup shoe assembly. A quick disconnect feature enables the cleaner cover to be de-coupled from the cleaner body to allow the debris to be easily removed with replacing the web-cleaner. The cleaner has a cleaner sump that is spring loaded to force contact of four strategically placed stops in the sump with a stationary back up shoe assembly allowing for higher precision of blade engagement with a transport web or a photoconductor. The web-cleaner has two wiper blades, each having each having a distinguishment such that the distinguishment distinguishes one wiper blade from the other wiper blade when the blades are locked into the cleaner sump by springs, to facilitate material removed from the web. The wiper cleaning blades and the cover assembly are easily replaceable by the operator in the correct order.
