In accordance with one aspect of the present exemplary embodiment, a printing system comprises a media feeder that receives and stores asymmetrically thick media from an outside source and outputs such media to the printing system via a feed mechanism. A conveyer system transports the asymmetrically thick media from the media feeder utilizing at least one linear belt wherein a sensor is employed to determine the presence of the asymmetrically thick piece of stock. A controller coupled to the conveyer determines the location and orientation of an image on a piece of the asymmetrically thick stock. An imaging system receives the asymmetrically thick media from the conveyer system and places an image on the media in the proper location and orientation based at least in part on information from the controller.

Systems, methods, and programs for adjusting an output orientation of multi-thickness media input marking data, determine a number of sheets of the multi-thickness media that is to be alternated within an output stack, and adjust the output orientation of at least one sheet of multi-thickness media to be output based on the determined number of sheets of the multi-thickness media to be alternated.

System, method, and program for stacking multi-thickness sheets of media

Systems, methods, and programs for adjusting marking data for use with alternately stacked multi-thickness media. The systems, methods, and programs input marking data and determine an orientation of sheets of the multi-thickness media that is alternated within a stack. The systems, methods, and programs adjust, for each sheet whose orientation is not consistent with the marking data, the marking data for that sheet such that the marking data for that sheet is consistent with the orientation of that sheet.

A toner of toner particles containing at least one binder, at least one color ant, and an external additive package comprised of zinc stearate and at. least one of silicon dioxide or titanium dioxide, wherein the amount of zinc stearate is limited to about 0.10 percent by weight or less of the toner. It has been surprisingly found that when the amount of zinc stearate is so limited, a developer formed from the toner exhibits excellent triboelectric charging and stability and excellent developer flow. When the developer is used in a magnetic brush development system, consistent, high quality copy images are formed substantially without any depletion defects over time.

At least three differently colored toners, designed for use together in forming a color image in an image developing device, have substantially the same melt flow index value. By substantially matching the melt flow index values of at least three toners of a set of toners, it has been found that the resultant color image has an overall excellent image quality, i.e., an excellent overall gloss level without any gloss banding. The toners may be made to have substantially the same melt flow index value in a carefully controlled process that includes forming a single toner by feeding at least one binder and at least one colorant into a mixing device to form a mixture, upon exit of the mixture from the mixing device, measuring a rheology property of the mixture with at least one monitoring device, and comparing the measured rheology property to a target property range that the measured rheology property must be within in order for the single toner to achieve the desired melt flow index value, wherein if the measuring indicates that the rheology property is outside of the target property range, feed amounts of the at least one binder or of the at least one colorant into the mixing device are adjusted, grinding the mixture, optionally together with a portion of one or more external additives to be added to the mixture, classifying the ground mixture, mixing the classified mixture with one or more external surface additives to obtain the single toner having the desired melt flow index value, and repeating the steps for each additional differently colored toner.

An assembly for use in a development unit including a mechanism and a member. A mechanism translates the member in a direction along the free edge. The member cooperates with a development roll and the mechanism cooperates with the roll and translates the member simultaneously with the rotation of the roll.

A drum supporting hub including a disk shaped member having a circular periphery, a hole extending axially through the center of the disk shaped member, and at least one long thin electrically conductive resilient member secured to the disk shaped member, the resilient member having a central section adjacent the hole and having opposite ends, each of the ends terminating into at least one pointed tip adjacent the circular periphery of the disk shaped member, and the resilient member having a major plane substantially parallel to the axis of the disk shaped member. This hub may be inserted in at least one end of a cylindrical electrostatographic imaging member to produce an imaging member assembly.
