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.

A method and system for producing a flat three-dimensional image utilizing acoustic transfer assist. An image is first developed in image bearing material onto the image bearing surface of a rendering device. A three-dimensional plastic sheet can be provided to the transfer section of the rendering device. Transfer of the image can then be accomplished as the plastic sheet comes into contact with the image-bearing surface. The transfer is facilitated by acoustic transfer assist technology associated with the rendering device.

The present disclosure provides a process for the preparation of developer compositions comprising: a first developer comprised of carrier and toner comprised of resin, pigment, polyolefin, compatibilizer, charge control agent, and metal oxide surface additive, and adding thereto a second developer comprised of carrier, and second compatibilizer, charge control agent, and metal oxide surface additive. The second developer can be directly dispensed into a developer housing.

Dispensing toner additives via carrier dispense

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.

Method for assessing transfer pressure uniformity

An apparatus, system and method are provided for causing one or more selectable strip radii associated with stripping a substrate from a belt in a fuser after an image has been fused to the substrate during a printing process. The fuser has a first member having a first surface, and a belt having a first portion that contacts the first surface of the first member. The fuser has a second member having a second surface that contacts a second portion of the belt in a region defining a fusing nip. The fuser has a stripping apparatus, positioned downstream of the fusing nip in a process direction, comprising one or more transducers that cause one or more respective transducer segments to move at a frequency that deflects one or more sections of the first portion of the belt to cause one or more selectable strip radii on demand.

Apparatus, method and system for controlling a strip radius in a printing system

An imaging forming device and a constrained transfer assist blade (CTAB) that provides for faster printing speeds, with an improved image-to-edge border specification is disclosed. An upper blade layer constrains pressure blades towards a lifter assembly in order to prevent the lower lying pressure blades from delaminating and a wear layer is formed around outer edges of the blade. Faster response times and improved trail edge flip defects as well as printing closer to the sheet edges is enabled.

Constrained transfer assist blade (CTAB) for improved print to edge performance

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.

Reusable transfer assist blade assembly for electro-photographic marking devices

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.

Method for automatically correcting transfer pressure non-uniformity using the cross process uniformity

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.

Interlocking fastener design prevents part movement

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&#xb0; 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.

Fast decay ultrasonic driver

Embodiments herein include a transfer assist blade that is adapted to bias media toward a marking device. The transfer assist blade is somewhat flexible and has a media contact edge positioned adjacent the marking device. The shape of the media contact edge comprises a curved shape. More specifically, the transfer assist blade assembly comprises a base and a transfer assist blade operatively connected to (or made an integral part of) the base. The curved media contact edge of the transfer assist blade comprises a center portion and end portions distal to the center portion, and the center portion extends a different distance from the base than the end portions extend from the base. Thus, the shape of the media contact edge can comprise one of a convex shape, a concave shape, and an irregular shape.
