摘要： An apparatus for electrically coupling a conductive layer of a photoreceptor to a reference potential, the photoreceptor being positionable between an operative position and a replacement position. The apparatus includes an electrically conductive brush which is electrically coupled to the reference potential. The apparatus further includes a mechanism for moving the conductive brush into electrical contact with the conductive layer in response to the photoreceptor being moved to the operative position and out of electrical contact with the conductive layer in response to the photoreceptor being moved to the replacement position.

摘要： An apparatus which advances a sheet through a transfer zone and into registration with information developed on a moving member. The sheet is advanced to a position wherein a leading portion thereof is immediately ahead of the transfer zone relative to the forward direction of movement of the moving member and a trailing portion thereof is within the transfer zone. The leading portion of the sheet forms a presentation angle of 7-10 degrees with the horizontal. The trailing portion of the sheet is advanced through the transfer zone at a first velocity and the leading edge of the sheet is advanced in a region immediately ahead of the transfer zone at a second velocity, which is less than the first velocity, so as to create a buckle in the leading portion of the sheet positioned immediately ahead of the transfer zone relative to the forward direction of movement of the moving member. The buckle functions to eliminate relative velocity between the photoconductive belt and any portion of sheet within the transfer zone so as to substantially eliminate slip between the sheet and the photoconductive belt.

摘要： Low lateral force rolls used in supporting a photoreceptor belt to minimize lateral belt motion on a multi-pass color copier. Single piece, widely spaced mounting through shafts are used in connection with side support structure of the module drawer to reduce inboard and outboard misalignment. An integral tensions slide/side plate guidance control system is employed to reduce misalignment of the tension roller. Use of these features aid in minimizing undesirable belt movement.

摘要： A registration transport and transfer module is located in a retractable drawer having a camshaft actuated by a lever. Rotation of the lever turns the cam which cooperates with a mounting to enable the transfer module to be lowered beneath a photoconductive belt. The drawer may then be pulled away from the machine and the transfer module pivoted about a point so as to expose portions of the copy sheet path for jam clearance.

摘要： A multiple pitch color registration system is disclosed for registering two images that are not precisely placed on a photoreceptor in an electrophotographic printing machine. The registration system is able to run asynchronously for a period of time and then to resynchronize in two different pitch modes. A two roll transfer loop for transferring the plurality of colors is phase locked to the photoreceptor position so that the two roll transfer loop follows the photoreceptor motion errors for maintaining accurate registration.

摘要： A method and apparatus for manipulating the velocity of a copy sheet in a color reprographic system creates a buckle in the copy sheet to decouple accelerations of the leading edge of the copy sheet from the portion that is in contact with the photoreceptor belt and reduces the buckle on long copy sheets for which the buckle can become large enough that the toner image on the body of the copy sheet can become disrupted by contact with stationary portions of the system. The method and apparatus also accelerates the leading edge of the copy sheet as the trailing edge disengages from the photoreceptor belt to prevent the uncontrolled trailing edge of lightweight copy sheets from contacting stationary portions of the system.
