摘要： A sensor and associated method is disclosed for detecting presence of a sheet which is being advanced on a photoreceptor of an electrophotographic printing device. The sensor includes a vibratory member which is configured to be positioned in contact with the photoreceptor. The sensor further includes a drive circuit operable to generate an input signal on a signal line which is coupled to the vibratory member. In addition, the sensor includes a sensing circuit operable to (i) determine if a current level of the input signal falls below a threshold value, and (ii) generate a control signal in response thereto. The control signal may be used to stop advancement of the photoreceptor such as in the case where the control signal indicates that the sheet is improperly being advanced on the photoreceptor such as into a cleaning station. Alternatively, the control signal may be used to commence operation of a machine component such as in the case where the control signal indicates that the sheet has advanced to a particular position along the path of advancement of the photoreceptor.

摘要： Acoustic Transfer Assist (ATA) systems are used in media printing devices to help transfer toner to paper by use of ultrasonic vibrations. The transducer is driven at its resonant frequency, though somewhat dampened. To shorten the decay time of the transducer when its vibration is not desired, a compensating signal is used. A reverse drive voltage is used during transducer shut-off. The reverse drive causes the transducer to vibrate at its normal resonant frequency, but at a 180° phase shift, causing the transducer to stop vibrating significantly faster than without a reverse drive. An open phase-locked loop system drives the transducer from resonance to rest. When the transducer stops vibrating, current to the reverse drive loop is cut off.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： An electrophotographic marking apparatus and 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, which are analyzed for 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.
