20090185825 | SPRING-LOADED WEB CLEANING APPARATUS FOR ELECTROGRAPHIC PRINTER - 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. | 07-23-2009 |
20100329739 | METHOD AND APPARATUS FOR ALIGNING COUPLED DIGITAL PRINT ENGINES - 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. | 12-30-2010 |

20120070209 | SYSTEM FOR COLLECTING WASTE TONER - 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. | 03-22-2012 |
20120070210 | METHOD FOR COLLECTING WASTE TONER - A method for collecting waste toner or developer in an electrophotographic printer includes 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. | 03-22-2012 |
20120099894 | METHOD FOR PREVENTING DAMAGE TO A PHOTOCONDUCTOR - A method for in situ replacement of a cartridge for an electrophotographic printer includes providing a photoreceptive member enclosed in a housing where the housing includes a retractable shield. The housing and photoreceptive member is inserted into the printer and the shield is retracted. | 04-26-2012 |
20120099895 | APPARATUS FOR PREVENTING DAMAGE TO A PHOTOCONDUCTOR - A system for in situ replacement of a cartridge for an electrophotographic printer includes a photoreceptive member in the cartridge; a retractable shield enclosing the photoreceptive member; and a retraction mechanism in the cartridge for retracting the retractable shield when the cartridge is inserted into the printer. | 04-26-2012 |
20120132311 | WASTE COLLECTION TUBE HAVING A LIVING HINGE - A waste collection tube for a dry electrophotographic printer is a molded, open construction. The molded open construction has mirror symmetry, and a first half and a second half connected by a flexible hinge. The first half and the second half open construction waste tubes have edges and labyrinth seals on the edges. A fastening device attaches the first half to the second half in a removable manner. | 05-31-2012 |
20120133074 | METHOD FOR MAKING WASTE COLLECTION TUBE - A method for making a waste collection tube for a dry electrophotographic printer includes molding an open construction waste tube which has mirror construction symmetry. A first half and a second half of the open construction waste tube are joined by a flexible hinge. The first half and the second half of the open construction waste tube is folded together along the hinge which joins the first half and the second half together. | 05-31-2012 |
20120141163 | DISENGAGING AN IMAGING MEMBER FROM A PHOTOCONDUCTOR - A method for engaging and disengaging an imaging member from a photoconductor includes enclosing the photoconductor in a shield; using a portion of the shield to maintain a space between the imaging member and the photoconductor; inserting the photoconductor and shield into an electrophotographic apparatus; and removing the shield which allows the imaging member to move into contact with the photoconductor. | 06-07-2012 |
20120177396 | EMISSION CONTROL FOR AN ELECTROPHOTOGRAPHIC PRINTER - An electrophotographic apparatus includes a photoconductor; a charging device for placing a uniform charge on the photoconductor; an image writer for writing an image on the charged photoconductor; a developer station for developing the image with toner; a transfer station for transferring the toned image to a receiver; a fixing unit for fusing the image to the receiver; environmental control system for removing airborne contaminants from the electrophotographic apparatus; the environmental control system includes a catalytic filter; and ozone is added prior to the catalytic filter when the contaminant is formaldehyde. | 07-12-2012 |
20120177397 | METHOD OF CONTROLLING EMISSIONS IN AN ELECTROPHOTOGRAPHIC PRINTER - A method for removing contaminants generated by an electrophotographic apparatus includes placing a uniform charge on a photoconductor; writing an image on the charged photoconductor; developing the image with toner; transferring the toned image to a receiver; fusing the image to the receiver; and removing airborne contaminants from the electrophotographic apparatus. | 07-12-2012 |
