An apparatus may include a transparent platen, a command interface, a scanner unit, a controller and an indicator. The command interface is to receive externally originating instructions including a selected scaling value, other than 100%, for a scanning operation of a document resting against the transparent platen, wherein contents of the document to be scanned are proportionally magnified or shrunk based on the selected scaling value The controller controls a scanner unit to capture a portion of the transparent platen, the portion having borders automatically determined and proportionally changed by the controller based upon the selected scaling value. The indicator provides a visible indication of the portion.

Scan area indication

Various embodiments and methods relating to a scan area indicator are disclosed.

A media feed system includes a roller and a selectively adjustable biasing system operatively connected to the roller, wherein the adjustable biasing system includes a spring coupled to an adjustable mount, the mount being movable to compress or decompress the spring.

Media feed system and method

Disclosed are embodiments for controlling one or more subsystems of an imaging system to manage average power to a fuser.

Controlling average power to a fuser

Systems, methods, and assemblies are provided for focusing light on a photoconductor. In one embodiment, an exposure assembly is provided. The exposure assembly includes an array of light-focusing structures. The light-focusing structures include a plurality of lenses. The individual lenses include a material that is deformable sufficient to focus light upon a photoconductor.

Exposure assemblies, printing systems and related methods

An electrostatic-writing mechanism for an image-formation device having an optical photoconductor (OPC) mechanism of one embodiment of the invention is disclosed that includes a light source and an array of micromirror devices. The light source is to emit light. The array of micromirror devices is to selectively direct the light onto the OPC mechanism in accordance with a portion of an image.

A color shifting composition and method useful as a coating on a surface. The composition comprises a layer of piezoelectric material disposed on the surface and a layer of electrically conductive disposed on the layer of piezoelectric material. A mechanism is included for changing an electromagnetic property of the layer of piezoelectric material. Thus, the surface has a first reflective or refractive property at one setting of the mechanism and another reflective or refractive property at another setting of the mechanism. In the illustrative embodiment, the layer of piezoelectric material and the layer of electrically conductive material are sufficiently thin to be transparent to electromagnetic energy in the frequencies of interest. In the illustrative embodiment, the mechanism for changing an electromagnetic property of the layer of piezoelectric material is a source of the electrical potential.

Piezoelectric coating

The present invention is directed to a fiber optic media thickness sensor used in a print media or document processing device. The invention is further directed to a method for measuring media thickness in a media processing device using a fiber optic sensor.
