Mechanism for substantially preventing trail edge smear of an image on a receiver member

摘要

In an electrostatographic reproduction apparatus, a mechanism which substantially prevents trail edge smear of an image on a receiver member. The reproduction apparatus has a flexible dielectric web entrained over at least a pair of support members defining a web travel path. Successive areas of the dielectric web are adapted to respectively carry a marking particle developed image. A marking particle developed image is transferable from the dielectric web to a receiver member brought into contact with the dielectric web. After transfer of the developed image to the receiver member, the receiver member is transported away from the dielectric web. A mechanism is provided for facilitating separation of a receiver member from the dielectric web. The separation mechanism includes an elongated member having a surface adapted to enable the dielectric web to pass thereover. The elongated member is positioned to engage the dielectric web along a line of contact transverse to the direction of travel of the dielectric member along the web travel path, downstream of the transfer means and upstream of the transport means to separate the receiver member from the dielectric web closer to the transfer means, and dampen perturbations in the dielectric web, whereby trail edge smear of an image on a receiver member is substantially prevented.
