摘要： An electrophotographic printing machine in which extraneous liquid developer material on a photoconductive belt is substantially removed therefrom by a cleaning roller. A backup roller is rotatively coupled to the cleaning roller with the photoconductive belt being interposed therebetween. The rollers are pressed into contact with the photoconductive belt. Either the photoconductive belt or backup roller are moved with movement of one frictionally moving the other. In this way, the cleaning roller and the belt move with the extraneous liquid material being removed fom the belt.

摘要： An optical scanning system for a variable-magnification electrophotographic copier includes a first scanning carriage reciprocated along a path by endless bands attached to the carriage at transversely spaced locations and driven purely by friction. Pulleys mounted on a second scanning carriage at transversely spaced locations roll between the drive bands and stationary guides to move the second carriage at half the speed of the first carriage. The second carriage may be shifted relative to the first carriage by moving it to a location at which arms lift the pulleys from the guides. A flywheel rotating at the desired scanning speed is coupled to the scanner drive train after the drive train has been smoothly accelerated to the desired scanning speed, and is uncoupled from the scanner drive train before the drive train is decelerated at the end of the scanning stroke. Misalignments between the separately driven ends of the first carriage are corrected by intercepting the carriage ends to induce differential slippage in the portions of the drive train coupled to the respective carriage ends. Similar misalignments between the separately driven ends of the second carriage are corrected by commonly rotating gears at the respective carriage ends that mesh with fixed teeth at one end of the scanning path. Misalignments between the first and second carriages are corrected by a gear, carried by one of the pulleys of the second carriage, which meshes with a normally immobilized gear as the second carriage moves past the same location.
摘要翻译：用于可变放大型电子照相复印机的光学扫描系统包括沿着路径往复运动的第一扫描托架，该第一扫描托架通过在横向间隔开的位置处附接到托架的环形带，并且完全由摩擦驱动。安装在第二扫描托架上的横向间隔位置的皮带轮在驱动带和固定引导件之间滚动以使第二托架以第一托架的一半的速度移动。通过将第二滑架移动到臂从引导件提起滑轮的位置，第二滑架可以相对于第一滑架移动。在驱动系统已经平稳地加速到期望的扫描速度之后，以期望的扫描速度旋转的飞轮被联接到扫描器传动系，并且在驱动系在扫描行程结束之前被减速之前与扫描器传动系分离。通过拦截滑架末端来校正第一滑架的单独驱动的端部之间的对准，以在连接到相应滑架端部的传动系的部分中引起差速滑动。通过在与扫描路径的一端处的固定齿啮合的相应滑架端部处的共同旋转的齿轮来校正第二滑架的单独驱动的端部之间的类似的对准。第一和第二托架之间的对准通过由第二托架的一个滑轮承载的齿轮来校正，该齿轮与第二托架移动通过相同位置时与正常固定的齿轮啮合。

摘要： Apparatus for repositioning the lens of a variable-magnification electrophotographic copier to change the image-side path length for a different magnification ratio and for concomitantly adjusting the shutter to compensate for the changed image-side path length. Actuation of a stepper motor rotates a pulley to tension a cable coupled to the lens, pulling the lens to the desired position of a linear track. A portion of the cable extends around a pulley having an axially projecting circumferentially extending ramp on one face. A follower engaging the ramp is coupled to slit-forming members adjacent to the photoconductor so that movement of the cable to reposition the lens produces a concomitant adjustment of the width of the slit to equalize exposure of the photoconductor over a substantially continous range of selected magnifications.

摘要： A copier in which a processing unit carrying a photoconductor drum, an exposure system, a liquid developer applicator, an excess liquid removal member, and a cleaning member is mounted for reciprocating movement with a forward stroke and a return stroke below a platen supporting the original document and in which a drive translates the unit while rotating the drum in synchronism with the translatory movement of the unit. A paper handling unit carrying a pair of registration rolls, a transfer corona, a copy paper pick-off, and a pair of delivery rolls, is mounted for reciprocating movement between a registration position at which its registration rolls receive a sheet from a supply of copy material and a position adjacent to the delivery end of the machine. In operation, the processing unit moves from its home position toward the registration position as the initial part of the image of the original is formed and developed. As it moves through the registration location, the processing unit picks up the paper handling unit and automatically provides a drive for the rollers thereof as the two units move together toward the delivery end of the machine. As the leading edge of the copy reaches its terminal location in the tray, movement of the units reverses and the copy delivery operation is completed during this reverse movement, before the paper handling unit returns to the registration position.

摘要： A novel liquid composition for developing latent electrostatic images whereby to form a gap between the developed image and the carrier sheet to which the developed image is to be transferred. The composition is such that it contains both charged and uncharged spacer particles. The spacer particles are of larger diameter than the toner particles so as to form a gap between the developed image and the carrier sheet to which they are transferred. The spacer particles, furthermore, have a specific gravity lower than the specific gravity of the carrier liquid, which may be a low-boiling hydrocarbon. This is accomplished by having a gas bubble enclosed in a portion of the material of which the spacer particles are formed, which material is preferably glass. The charged spacer particles may be coated with a polymer of which the toner particles are formed. Both the coated spacer particles and the toner particles bear the same charge. The remainder of the spacer particles are substantially uncharged. The uncharged spacer particles will remain on the background areas of the developed image and prevent the carrier sheet from absorbing liquid present in the developing composition. The charged spacer particles will go to the image areas and become agglomerated with the toner.
