Disclosed is an improvement to transfer assist blades, such as disclosed in United States Patent No. 4,947,214, to Baxendell et al., which have been used in printing systems. Typically, the blade is placed adjacent to an image transfer device, such as a corotron, to contact the backside of a copy sheet to substantially eliminate spaces between the copy sheet and a developed image on a photoreceptor. The blade comprises a Mylar film with a predetermined width corresponding to a selected size of the copy sheet. The Mylar film is supported on the shield of the corotron, and is actuated by a solenoid system mechanically engaged to a metal plate, which is, in turn, moved by the solenoid to move the Mylar film to the backside of the copy sheet.
