A tension and detensioning assembly includes a frame and a moveable tensioning roll for tensioning the continious loop belt. The moveable tensioning roll has an axis, a first end, a second end, a first position for tensioning the continous loop belt, and a second position when the continous loop belt is detensioned. When the moveable tensioning roll is in the second position, the first end is spaced a first distance from the first position, and the second end is spaced (from the first position) a second distance that is different from the first distance in order to enable safe, efficient and controlled, non-slipping removal and reinstallation of the flexible closed loop photoreceptor belt. The tensioning and detensioning assembly also includes a first moving apparatus for moving the moveable tensioning roll into the first position, and a second moving apparatus including a release device in the form of an elongate member having a first end and a second end, a first edge and a second edge having a first cam surface at the first end and a second cam surface at the second end for moving the first end through the first distance, and the second end through the second distance, thus moving the moveable tensioning roll into the second position, and thereby enabling controlled and non-slipping removal and reinstallation of the belt or photoreceptor.

A method and printing device positions a conductive film applicator adjacent a printing media transport within a printing device. The conductive film applicator is positioned between the printing media input and the marking station. As the printing media moves by the conductive film applicator, the conductive film applicator applies a conductive film to the printing media. After the conductive film has been applied to the printing media, the printing media is moved to the marking station and printing operations are performed on the printing media. After printing is complete, the printing media can be output from the printing device.

340687

An apparatus and method for accurately establishing a predetermined gap between two surfaces, and in particular, between a corona generating device and a photoreceptive member in an electrostatographic printing machine, comprising a first conductive member for being mounted on a first of the two surfaces, a second conductive member for being placed on a second of the two surfaces, the combined thickness of the first and second conductive members being substantially equal to the predetermined gap. A device is coupled between the first and second conductive members, for sensing electrical continuity therebetween.

355221

An adjustable support assembly for adjustably supporting a corona generating device at a selected distance from a photoreceptive surface, wherein a fixedly mounted support bracket and an adjustable support bracket are mounted in a cooperatively nested relationship such that reciprocating movement can be affected between the adjustable support bracket and the fixedly mounted support bracket. The adjustable support assembly is provided with support blocks for adjusting the gap between the corona generating device and the photoreceptive surface from a single general location.

355274

An apparatus which transfers a developed image from a photoconductive surface to a copy sheet. The apparatus includes a corona generating device arranged to charge the copy sheet. This establishes a transfer field that is effective to attract the developed image from the photoconductive surface to the copy sheet. A blade is moved from a nonoperative position spaced from the copy sheet, to an operative position, in contact therewith. The blade presses the copy sheet into contact with at least the developed image on the photoconductive surface to substantially eliminate any spaces between the copy sheet and the developed image during transfer of the developed image from the photoconductive surface to the copy sheet.

355212

An electrophotographic printing machine in which a moving photoconductive belt is supported in the region of the processing stations thereof. The photoconductive belt is guided in an endless path of movement. The region of the photoconductive belt opposed from at least one of the processing stations is maintained substantially planar with photoconductive belt flutter being substantially dampened.
