    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 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： 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： An apparatus for advancing a sheet in a predetermined path is described. The apparatus includes a mechanism for advancing the sheet in the path. The apparatus further includes a first mechanism for controlling movement of the sheet while it is being advanced in the path, the first controlling mechanism being in contact with the sheet in a first mode of operation and being spaced apart from the sheet in a second mode of operation. Moreover, the apparatus includes a second mechanism for controlling movement of the sheet while it is being advanced in the path, the second controlling mechanism being in contact with the sheet in a first mode of operation and being spaced apart from the sheet in a second mode of operation. The apparatus additionally includes an intermediate member movable between a first location and a second location, each of the controlling mechanisms being positioned in one of its respective modes of operation in response to the intermediate member being positioned at its first location and being positioned in the other of its respective modes of operation in response to the intermediate member being positioned at its second location.

    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.
