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 |
20120163869 | Secure document printing method and system - A method and system for printing documents with one or more embedded security features is provided. Security features are embedded in the document by co-printing magnetic and non-magnetic toner on a receiver before fixation by a fixing station. The combination of magnetic and non-magnetic toners in the image results in image elements that easily show alteration or are undetectable by visual means. | 06-28-2012 |
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 |
