Provide herein is a description of a bias charging member that includes a conductive core, and an outer surface layer disposed on the conductive core. The outer surface layer includes carbon black and acrylonitrile-butadiene-styrene.

Bias charging overcoat

Provided are media vacuum transport systems including media vacuum transport members, methods of making media vacuum transport members, and method of transporting media. In accordance with various embodiments, there is a media vacuum transport system including a vacuum plenum one or more transport members configured to rotate around the vacuum plenum and wherein at least one of the one or more transport members can include a substrate, the substrate comprising a plurality of holes extending from a first side proximate to the vacuum plenum to a second side proximate to the media, and a top coat layer disposed over the substrate, wherein the top coat layer can include a plurality of particles dispersed in a resin to provide an average surface roughness Ra of about 2 &#x3bc;m to about 100 &#x3bc;m.

Vacuum transport belts

Provide herein is a bias charging member that includes a conductive core, and an outer surface layer disposed on the conductive core. The outer surface layer includes carbon black and polycarbonate.

There is described a bias charging member that includes a conductive core and an outer surface layer on the conductive core. The outer surface layer includes a resin of aminoplast and one of polyol or nylon, a conductive additive and p-toluene sulfonic acid. There is also described a method of refurbishing bias charging members.

The presently disclosed embodiments are directed to charge transport layers useful in electrostatography. More particularly, the embodiments pertain to an improved electrostatographic imaging member having a charge transport layer that is dual-dopant, wherein operating life improvement is achieved by incorporating a small amount of compatible thermalsetting resin and polyhedral oligomeric silsesquioxane into the layer. Incorporation of these resins have been shown to increase charge transport life.

Imaging member

A photoconductor containing a photogenerating layer, and at least one charge transport layer, and a top polymeric overcoat layer in contact with, and contiguous to the charge transport layer, and which overcoat layer includes an indium tin oxide.

Metal oxide overcoated photoconductors

A ghost removing device for a marking apparatus includes a photoreceptor, a primary charging device, an erase light generating device to generate an erase light when activated, a voltage source to supply a charge voltage to the primary charging device, and a controller configured to control the at least one voltage source to supply the charge voltage to the primary charging device and to activate the erase light generating device substantially simultaneously after transfer of a toned image within a marking cycle. A ghost removing method for a marking device with a photoreceptor, including performing a partial print cycle, applying an erase light to the photoreceptor, and applying a charge voltage to the photoreceptor, wherein the erase light and the charge voltage are applied to the photoreceptor substantially simultaneously after completion of the partial cycle.

Methods and devices for removing latent image ghosts photoreceptors

A method for determining the approximate surface conductivity of a photoreceptor surface. The method involves forming a latent image of a series of lines of different widths on the surface, developing the image, and then printing the image. Based on which lines print, the surface conductivity can be computed once the developability of isolated lines is established through a calibration procedure.

Effective surface resistivity through image analysis

A mandrel for transporting hollow cylinders including an elongated arm having a first end and a second end, an expandable disk supported at the first end and means supported at the second end to expand the expandable disk, the mandrel arm comprising an elongated body having an imaginary axis and at least three fins extending substantially radially from the arm, each of the fins having an alignment shoulder adjacent the first end adapted to receive an end of a hollow cylinder and to coaxially align the cylinder with the elongated arm.

Low energy transfer mandrel and process for using mandrel

A mandrel for transporting a hollow cylinder including an elongated arm, a dish shaped disk adjacent one end of the elongated arm, the dish shaped disk having a flexible lip flared inclined away from the elongated arm, the flared flexible lip having a circular outermost edge, and a reciprocable presser means adapted to partially flatten at least a portion of the flexible lip adjacent to and including the outermost edge of the lip toward the elongated arm to increase the length of the circumference of the circular outermost edge of the lip. This mandrel is used in a process for coating hollow cylinders.

Mandrel with flared, dish shaped disk and process for using mandrel

A mandrel including an elongated arm having a first end and a second end, a reciprocatable shaft coaxially aligned with and extending through the arm, a first end of the shaft extending beyond the first end of the arm and a second end of the shaft extending beyond the second end of the arm, a presser means mounted at the first end of the shaft, an expandable disk shaped member coaxially aligned with and slidably mounted on the shaft between the presser means and the first end of the arm, a compression means mounted on the second end of the shaft, and a resilient helical spring coaxially aligned with and slidably mounted on the shaft between the presser means and the compression means, the compression means adopted to apply compression pressure to the disk shaped member and to the helical spring. This mandrel is used in a process for coating hollow cylinders.
