20090080951 | Interlocking fastener design prevents part movement - When a TAB assembly is used in the transfer station of an electrostatic marking system, the blade used in the TABs becomes deformed or improperly aligned due to lateral movement of the clamp, held by rivets, which is used to maintain proper blade alignment. Provided herein is a simple, yet effective, way to secure this clamp with embedded burrs so that the useful life of the TAB is more than doubled over prior art TABs. | 03-26-2009 |
20090080956 | IN-LINE PRINTING MEDIA TREATMENT FOR PRINTING ON NON-PAPER PRINTING MEDIA AND THICK PRINTING MEDIA - A method and printing device positions a conductive film applicator adjacent a printing media transport within a printing device. The conductive film applicator is positioned between the printing media input and the marking station. As the printing media moves by the conductive film applicator, the conductive film applicator applies a conductive film to the printing media. After the conductive film has been applied to the printing media, the printing media is moved to the marking station and printing operations are performed on the printing media. After printing is complete, the printing media can be output from the printing device. | 03-26-2009 |
20100046992 | Reversible Eccentric Actuator Widens Optical Sensor Setting Latitude - An improved flag-actuator (actuator) is provided for use in an electrophotographic marking system. This actuator is reversible providing sides | 02-25-2010 |
20110150514 | METHOD FOR AUTOMATICALLY CORRECTING TRANSFER PRESSURE NON-UNIFORMITY USING THE CROSS PROCESS UNIFORMITY - This invention relates to an electrophotographic marking apparatus and provides an automatic method for automatically scanning and correcting TAB pressure non-uniformity using a cross-process uniformity controller and a closed loop system. The TAB is contacted with an image on a photoreceptor surface to leave its imprint or footprint on the image. Sensing said footprint and marking indicated changes in the TAB performance and pressure. This method uses a CPUC full width array in conjunction with a software version for assessing TAB performance. This method continuously monitors the TAB performance during the running of a marking apparatus. | 06-23-2011 |
20110188903 | APPARATUSES INCLUDING A VIBRATING STRIPPING DEVICE FOR STRIPPING PRINT MEDIA FROM A BELT AND METHODS OF STRIPPING PRINT MEDIA FROM BELTS - Apparatuses useful in printing onto media and methods for stripping print media from belts are disclosed. An exemplary apparatus useful in printing onto media includes a first member including a first surface; a second member; a fixing belt supported on the second member, the fixing belt including an inner surface and an outer surface, the first surface and the second surface forming a nip at which media are received; and a vibrating stripping device disposed between the second member and the inner surface of the fixing belt. The vibrating stripping device includes a stripping member including a stripping surface and a drive mechanism. The drive mechanism produces vibration of the stripping surface and the fixing belt, and the vibration of the fixing belt assists separation of media passed through the nip from the outer surface of the fixing belt adjacent to the stripping surface of the stripping member. | 08-04-2011 |
20120070203 | REUSABLE TRANSFER ASSIST BLADE ASSEMBLY FOR ELECTRO-PHOTOGRAPHIC MARKING DEVICES - As set forth herein, a reusable transfer assist blade (TAB) assembly includes a replaceable blade assembly that is locked into position between a clamp assembly and an extruded portion of the TAB assembly. When the blade assembly requires replacement, spring tables on the clam assembly are biased upward to release the clamp assembly from the extruded portion, and the clamp assembly is rotated about a clamp tab-clamp pocket interface at the top of the TAB assembly. The blade assembly is removed and replaced, the clamp assembly is rotated back into position against the extruded portion, and the spring tabs re-engage interlocking features on the extruded portion to lock the replacement blade in position. The expensive extruded portion and clamp assembly are thus reused and the inexpensive blade assembly is discarded or recycled. | 03-22-2012 |
20120120429 | SYSTEM AND METHOD FOR AUTOMATICALLY RENDERING LABELING SERVICE PRINTS WITH PRINT ENGINE PARAMETERS - A system and method for automatically rendering labeling service prints with print engine parameters. An auto-labeling application can be configured in association with a print engine controller for labeling the service prints with the print engine parameters via a built-in marker integrated with a fault multi-function device. A portable inline marker can also be separately attached to a baffle assembly of the fault device and connected to the print engine controller via a connector in order to receive the print engine parameters from the print engine controller. A setup routine configured with the auto-labeling application can be employed to customize the service print labels in a modular format and the parameters can be appended to each other based on the information required to troubleshoot the fault multi-function device. Such an approach effectively provides labeling of the service prints with enhanced service proficiency and customer satisfaction and reduces service time with respect to the fault multi-function device. | 05-17-2012 |
20120180573 | PIEZOELECTRIC SENSORS FOR AUTOMATIC MEASUREMENT OF NIP WIDTH FOR FUSER MEMBER CONTROL - According to aspects of the embodiments, an apparatus and method is proposed to detect nip width by use of at least one piezoelectric (PZT) crystal embedded into a roll at both the inboard and outboard ends. A piezoelectric (PZT) crystal generates a charge when subjected to a load and when the load is released. The PZT generate signal is channeled to the ends of the roller such as with a brush contact to be processed and used within machine control. The duration measure from application and released of the load is indicative of the dwell time and the amplitude PZT generate signal is a function of the pressure. The time and amplitude of the PZT signal can be calibrated to correlate directly to nip width or pressure and tracked in machine control. | 07-19-2012 |
20120237239 | METHOD FOR ASSESSING TRANSFER PRESSURE UNIFORMITY - Systems and methods are described that facilitate automatically and uniformly depositing a marking material on transfer assist blade (TAB) petals to improve TAB pressure profile accuracy. A TAB liftoff timing value is adjusted in non-volatile memory (NVM) to delay TAB liftoff beyond a trailing edge of a page on which an oversized (in the process direction) image being printed. Toner deposited on a photoreceptor belt beyond the trailing edge of the page is picked up by the TAB petals once the trailing edge of the page has passed the TAB. The TAB is then disengaged and re-engaged against a backside of a next page, where the TAB petals deposit the uniformly acquired toner to generate the TAB pressure profile. | 09-20-2012 |
20120281045 | Latching Assembly For A Printhead - A latching assembly for mounting a printhead to a plate assembly of a printing machine includes a first elongated actuator and a second elongated actuator defining a bore to slidably receive the first actuator. A first spring is disposed between the heads of the first and second actuators, while a second spring is disposed between the second actuator and the printhead to exert a clamping force. A cam mechanism is defined between the plate assembly and the ends of the actuators that is configured to draw the head of the first actuator toward the plate assembly upon rotation of the first actuator and to independently draw the head of the second actuator toward the plate assembly upon rotation of said second actuator. Movement of said first actuator exerts an initial clamping force while movement of the second actuator produces a final clamping force on the printhead. | 11-08-2012 |
