Techniques are disclosed for supporting objects in a tray and moving different portions of the objects at different rates for inputting or outputting from an objects processor. These techniques may be applied to stacking objects that has a thickness at one end greater than the thickness at another end, for example, resulting in stacking height of the thicker end increasing faster than the stacking height of the other thinner end.

Tray for non-uniform thickness objects

A leveling device assists in support of stackable objects having a non-uniform thickness, such as DocuCards, in a stackable tray. The stackable tray includes a pivoting tray that can be pivoted from a full sheet stack position to an empty sheet stack position. A valley removal mechanism is provided on the pivoting tray to variably support an intermediate portion of the bottom of the stack to compensate for and remove a valley created intermediate ends of the stack due to an aggregate effect of stack media of non-uniform thickness. The valley removal mechanism preferably includes a support surface that contacts a bottom of the stack, a ramp defining a ramp profile, and a ramp follower that guides the support surface to a variable orientation that compensates for the valley as the stack height changes.

Leveling device for removing valleys in stacked objects

A method for monitoring filming levels on a photoreceptor surface of a printing machine includes the use of an enhanced toner area coverage sensor to measure level of filming of substantially the entire photoreceptor surface, the sensor being located at a point downstream from a cleaning station of the printing machine. When the measurement indicates that the filming is unacceptably high on a portion of the photoreceptor surface, corrective action is implemented, for example filming removal. The sensor is preferably mounted in a manner such that it may be moved over substantially the entire surface of the photoreceptor. Also, an electrostatic voltmeter is preferably mounted along with the sensor in order to monitor the charging of the photoreceptor surface.

An electrostatic copying machine including a drum that supports a photoreceptor belt. The drum includes a mechanism for reducing the drum perimeter, allowing a user to replace the photoreceptor belt.

A reservoir wick system in an apparatus for fixing a toner image on image supporting members including a first and second roller for conveying the image supporting member therebetween and fixing the toner image on the image supporting member, an applicator in contact with the first roller for applying offset preventing liquid to the first roller and forming a nip for receiving said image supporting member, the applicator disposed underneath the first roller and including a woven cloth for retaining the offset preventing liquid, the flow offset prevention liquid to the first roller being drawn up by capillary action and controlled by the weave of the woven cloth.
