Abstract:
1. A reprographic device that provides controlled velocity decoupling for copy sheet hand-off between a registration drive nip and a photoreceptor, comprising: a controller that receives an image signal representing an image to be printed; a single charge retentive surface; a charging station that charges the charge retentive surface to a relatively high potential; an exposure station that receives images signals from the controller and records an electrostatic latent image on said charge retentive surface; a development station that deposits toner over the electrostatic latent image on said charge retentive surface to form a toner image; a single transfer station including a single transfer member that transfers the toner image directly from said charge retentive surface to a copy sheet; and a registration system for registering copy sheets with said charge retentive surface without forming a buckle within the copy sheets in close proximity to a non-intermittently driven driver roll and idler roll nip of said registration system prior to reaching said charge retentive surface, said registration system including a decoupling device configured to eliminate artifacts associated with any velocity mismatch while simultaneously allowing control to be maintained over said copy sheets during the hand-off from said registration system while tacking directly to said charge retentive surface prior to reaching said transfer station without using a buckle sensor in close proximity to said decoupling device, said decoupling device including a one-way clutch mounted with respect to said driver roll such that it allows said driver roll to rotate freely at an increased speed while said copy sheets are being pulled solely by said charge retentive surface once they are tacked to said charge retentive surface.
