Slidably mounted wiper system

An electrophotographic printing machine of a type in which a light source is employed to discharge selected portions of a charged photoconductive member adapted to have successive electrostatic latent images of original documents recorded thereon, comprising:

• a slidable photoreceptor module for supporting said photoconductive member, said slidable module being movable relative to the light source such that said photoconductive member is slidably displaceable with respect to the light source;
• wiper means for engaging with a light emitting surface of the light source;
• and
• means for mounting said wiper means on said slidable photoreceptor module such that said wiper means is slidably engaged with the light emitting surface of the light source to provide cleaning action thereagainst in accordance with sliding movement of said slidable photoreceptor module.
