Patent ID: 8311440

Claim:
A reprographic device, comprising: an apparatus that receives an image signal representing an image to be printed; a charge retentive surface; a charging station that charges the charge retentive surface to a relatively high potential; an exposure station that receives images signals from said apparatus and records an electrostatic latent image on said charge retentive surface, said exposure station including a raster output scanner with a light exit aperture; a development station including a developer customer replacement unit that deposits developer over the electrostatic latent image on said charge retentive surface to form a developed image; a transfer station that transfers the developed image from said charge retentive surface to a recording media; and a cleaning member that is a part of and fixedly attached against independent movement to said developer customer replacement unit and adapted to be moved only when said developer customer replacement unit is moved and positioned to be in continual contact with said light exit aperture such that insertion of said developer customer replacement unit into said reprographic device cleans said light exit aperture a first time and removal of said developer customer replacement unit from said reprographic device cleans said light exit aperture of said raster output scanner a second time.
