Abstract
A printer and method have been developed that vary the force applied by the transfer roller against the imaging member to facilitate the climb of the transfer roller as the media enters the nip and then apply an appropriate force for effective transfer of an image from the imaging member to the media. The printer includes an imaging member, a transfer roller located proximate to the imaging member, a controller being configured to generate signals that control movement of the transfer roller, and a displaceable linkage coupled to the controller to receive signals from the controller that control movement of the transfer roller and coupled to the transfer roller to move the transfer roller into and out of contact with the imaging member, the displaceable linkage applying a first move of the transfer roller into contact with the imaging member to form a transfer nip at a commanded first force, the displaceable linkage applying a second move to the transfer roller at a commanded second force, and the displaceable linkage applying a third move to the transfer roller at a commanded third force.
