Abstract
A device and method of enhancing contact between a photoconductive member of a electrophotographic printing machine and the paper to which an electrostatic latent image is to be transferred uses an array of wiper blade segments mounted on a common shaft. Each segment is attached to the shaft for limited rotational movement on the shaft in opposition to a torsion spring. The torsion spring biases the blade segment towards the paper. Some of the blade segments are operatively associated with a stop mechanism to control the length of the wiper blade array in accordance with the size of the paper being processed. The stop mechanism prevents movement of the blade segment into engagement with the paper by restraining movement of the segment against its torsion spring.
